Biomimetic approaches to complex craniofacial defects |
p. 4 |
Chad M Teven, Sean Fisher, Guillermo A Ameer, Tong-Chuan He, Russell R Reid DOI:10.4103/2231-0746.161044 PMID:26389027The primary goals of craniofacial reconstruction include the restoration of the form, function, and facial esthetics, and in the case of pediatric patients, respect for craniofacial growth. The surgeon, however, faces several challenges when attempting a reconstructive cranioplasty. For that reason, craniofacial defect repair often requires sophisticated treatment strategies and multidisciplinary input. In the ideal situation, autologous tissue similar in structure and function to that which is missing can be utilized for repair. In the context of the craniofacial skeleton, autologous cranial bone, or secondarily rib, iliac crest, or scapular bone, is most favorable. Often, this option is limited by the finite supply of available bone. Therefore, alternative strategies to repair craniofacial defects are necessary. In the field of regenerative medicine, tissue engineering has emerged as a promising concept, and several methods of bone engineering are currently under investigation. A growth factor-based approach utilizing bone morphogenetic proteins (BMPs) has demonstrated stimulatory effects on cranial bone and defect repair. When combined with cell-based and matrix-based models, regenerative goals can be optimized. This manuscript intends to review recent investigations of tissue engineering models used for the repair of craniofacial defects with a focus on the role of BMPs, scaffold materials, and novel cell lines. When sufficient autologous bone is not available, safe and effective strategies to engineer bone would allow the surgeon to meet the reconstructive goals of the craniofacial skeleton. |

Vismodegib hedgehog-signaling inhibition and treatment of basal cell carcinomas as well as keratocystic odontogenic tumors in Gorlin syndrome |
p. 14 |
Patrick Booms, Marc Harth, Robert Sader, Shahram Ghanaati DOI:10.4103/2231-0746.161049 PMID:26389028Vismodegib hedgehog signaling inhibition treatment has potential for reducing the burden of multiple skin basal cell carcinomas and jaw keratocystic odontogenic tumors. They are major criteria for the diagnosis of Gorlin syndrome, also called nevoid basal cell carcinoma syndrome. Clinical features of Gorlin syndrome are reported, and the relevance of hedgehog signaling pathway inhibition by oral vismodegib for maxillofacial surgeons is highlighted. In summary, progressed basal cell carcinoma lesions are virtually inoperable. Keratocystic odontogenic tumors have an aggressive behavior including rapid growth and extension into adjacent tissues. Interestingly, nearly complete regression of multiple Gorlin syndrome-associated keratocystic odontogenic tumors following treatment with vismodegib. Due to radio-hypersensitivity in Gorlin syndrome, avoidance of treatment by radiotherapy is strongly recommended for all affected individuals. Vismodegib can help in those instances where radiation is contra-indicated, or the lesions are inoperable. The effect of vismodegib on basal cell carcinomas was associated with a significant decrease in hedgehog-signaling and tumor proliferation. Vismodegib, a new and approved drug for the treatment of advanced basal cell carcinoma, is a specific oncogene inhibitor. It also seems to be effective for treatment of keratocystic odontogenic tumors and basal cell carcinomas in Gorlin syndrome, rendering the surgical resections less challenging. |

Is it worthy? Removal of level IIB nodes during selective neck dissection (I-III) for oral carcinomas |
p. 20 |
Anirudh Bhattacharya, Dwarkadas Adwani, Nitin Adwani, Vijay Sharma DOI:10.4103/2231-0746.161052 PMID:26389029Aims: The aim was to correlate the incidence of metastasis to Level IIB of neck lymph nodes (LNs) for oral cavity carcinomas with the site, size, and histological grade of tumor. Settings and Design: Total 30 patients of either sex, with biopsy-proven oral squamous cell carcinoma of any site, size or histologic grade, but N0/N1 were taken for selective neck dissection (SND). Materials and Methods: Thirty patients who underwent SND for oral carcinoma were analyzed for the relation of the site, size, and histological grade of malignancy with metastatic involvement to Level IIB nodes. Level IIB nodes were dissected separately and sent for histopathological examination. Statistical Analysis Used: The data were entered in custom written software in Excel (MS office 2007, Windows XP) and the data were analyzed using statistical software STATA version 10.0. The statistical test used for the analysis of the result was Chi-square test. The critical level of statistical significance chosen was P < 0.05. Results: Only 2 of 30 patients (6.6%) had the involvement of Level IIB neck nodes. There was no relation between the site, size, and histologic grade of primary tumor with the metastasis to Level IIB. The Level IIA nodes were positive in both the positive cases of Level IIB. Conclusions: For tumors in oral cavity (N0/N1), while performing elective or therapeutic SND the dissection of Level IIB nodes could be omitted as it will provide significant decrease in operative time and also less of spinal accessory nerve trauma-related complications. |

Long-term quality of life after intensified multi-modality treatment of oral cancer including intra-arterial induction chemotherapy and adjuvant chemoradiation |
p. 26 |
Adorján F Kovács, Ulrich Stefenelli, Gerrit Thorn DOI:10.4103/2231-0746.161055 PMID:26389030Background: Quality of life (QoL) studies are well established when accompanying trials in head and neck cancer, but studies on long-term survivors are rare. Aims: The aim was to evaluate long-term follow-up patients treated with an intensified multi-modality therapy. Setting and Design: Cross-sectional study, tertiary care center. Patients and Methods: A total of 135 oral/oropharyngeal cancer survivors having been treated with an effective four modality treatment (intra-arterial induction chemotherapy, radical surgery, adjuvant radiation, concurrent systemic chemotherapy) filled European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and HN35 questionnaires. Mean distance to treatment was 6.1 (1.3-16.6) years. Results were compared with a reference patient population (EORTC reference manual). In-study group comparison was also carried out. Statistical Analysis: One-sample t-test, Mann-Whitney-test, Kruskal-Wallis analysis. Results: QoL scores of both populations were well comparable. Global health status, cognitive and social functioning, fatigue, social eating, status of teeth, mouth opening and dryness, and sticky saliva were significantly worse in the study population; pain and need for pain killers, cough, need for nutritional support, problems with weight loss and gain were judged to be significantly less. Patients 1-year posttreatment had generally worse scores as compared to patients with two or more years distance to treatment. Complex reconstructive measures and adjuvant (chemo) radiation were main reasons for significant impairment of QoL. Conclusion : Subjective disease status of patients following a maximized multi-modality treatment showed an expectable high degree of limitations, but was generally comparable to a reference group treated less intensively, suggesting that the administration of an intensified multi-modality treatment is feasible in terms of QoL/effectivity ratio. |

Secondary bone grafting of the cleft maxilla following reverse quad-helix expansion in 103 patients |
p. 32 |
Omri Emodi, Dani Noy, Hagai Hazan-Molina, Dror Aizenbud, Adi Rachmiel DOI:10.4103/2231-0746.161056 PMID:26389031Introduction: The main points to consider in secondary alveolar bone grafting (ABG) of cleft patients are age at the time of surgery, the type of bone graft, and pre/postorthodontic expansion of the upper jaw. Purpose: The aim of this study is to evaluate the reverse quad-helix (RQH) expander device. Does RQH improve the surgical procedure before ABG? We will evaluate the outcome of the procedure, duration of the operation, hospitalization time, satisfaction of the surgeon with this procedure and the success of the bone graft in the long-term. Patients and Methods: We reviewed the medical records of 103 cleft patients who underwent secondary bone grafting at our institution between 2001 and 2012. All patients were treated presurgically with a RQH appliance to expand the cleft area. The following data were recorded for each of the patients: Unilateral/bilateral cleft, surgery time, hospital stay, success/failure, and follow-up. Conclusion: Presurgical orthodontic application of the RQH expander in the cleft area enabled improved anterior expansion rather than posterior expansion. This technique improves access for surgery and bone grafting, the use of RQH facilitates the improved manipulation of the nasal mucosa via direct view due to the wide separation of the alveolar segments in the cleft area. Furthermore, this gap enables improved access for the bone grafting procedure, shortens the surgery time and provides stable maxillary transverse correction. |

A single center experience of craniofacial tissue expansion and reconstruction |
p. 37 |
SM Balaji DOI:10.4103/2231-0746.161057 PMID:26389032Introduction: Tissue expansion is a versatile technique for craniofacial soft tissue defects. It has been extremely useful to restore the form and function along with good esthetics that were otherwise unobtainable. Objectives: To review the use of tissue expansion in the craniofacial region, with particular emphasis on indication, site, days, volume of the defect and tissue expansion used along with complications. Materials and Methods: Retrospective review of data on 18 expanded flap reconstructions performed in 14 patients during the period 2008-2013. Tissue expanders were placed on a subcutaneous plane above the fascia and inflated weekly. The expanded skin was used as a transposition flap for the reconstruction. Data were collected from archival records and tabulated in SPSS. Descriptive statistics, Kruskal-Wallis and Mann-Whitney tests were applied as required and a P ≤ 0.05 was taken as significant. Results: Trauma contributed to greater number of defects (57.1%). The most common defect occurs in face/cheek compartment (57.15%) followed by nose (35.71%). Owing to ease of access and better results, more expanders have been placed in cheek (50%), followed by neck (33.33%). The mean defect size was 2983.58 ± 828.27 mm 2 , required 32.14 ± 6.31 days, 335.6 ± 156.51 ml in 5.29 ± 1.5 cycles of tissue expansion. The mean rate of expansion was 59.17 ± 16.27, 69.11 ± 30.19 and 62.6 ± 25.75 for forehead, face/cheek and neck cases respectively (P = 0.873). Discussion: Laxity of skin appears to be a good indicator of the rate of the expansion. The most favorable site for tissue expansion is cheek followed by neck. The study also shows that tissue expansion is an efficient and valuable technique for reconstruction of large craniofacial skin defects. |

Transpalatal distraction for the management of maxillary constriction in pediatric patients |
p. 44 |
Nicolai Adolphs, Nicole Ernst, Bodo Hoffmeister, Jan-Dirk Raguse DOI:10.4103/2231-0746.161058 PMID:26389033Context: The management of severe maxillary constriction can be challenging. For that purpose surgically assisted maxillary expansion by transpalatal distraction (TPD) can typically be recommended after skeletal maturity. However in selected cases bone borne transpalatal distraction devices can contribute to improve maxillary constriction considerably earlier already during mixed dentition. Aims: To assess the possibility of bone borne transpalatal distraction in pediatric patients. Settings and Design: Clinical paper. Materials and Methods: Since 2010 TPD has been applied to six pediatric patients during mixed dentition when severe maxillary constriction was present and conventional orthodontic widening has already failed. Individually selected devices (Surgitec, Belgium) were inserted in general anaesthesia and distraction was performed according to well known parameters. Results: Maxillary constriction could be improved in all six patients without any drawbacks by bone borne devices during mixed dentition. Skeletal conditions were obviously improved for subsequent orthodontic or orthognathic therapy without functional impairment. Follow-up is up to 36 months after device removal. Conclusions: Transpalatal Distraction is recommendable in selected pediatric patients if massive growth disturbance is present or has to be expected. TPD allows for individually adapted maxillary expansion by selection and positioning of appropriate devices in combination with intraoperative testing of maxillary movements and controlled bone removal. |

Evaluation of isoamyl 2-cyanoacrylate tissue adhesive in management of pediatric lacerations: An alternative to suturing  |
p. 49 |
Vishakha N Devrukhkar, Rahul J Hegde, Sumedh S Khare, Tanvi A Saraf DOI:10.4103/2231-0746.161059 PMID:26389034Aims: A study was conducted to evaluate the benefits of cyanoacrylate tissue adhesive as an alternative to suturing in management of pediatric lacerations. Materials and Methods: A total of 7 patients were evaluated and followed for 3-month. The wound was evaluated on 1 st , 3 rd , and 7 th postoperative day for swelling, infection, gaping and pain and at 1 st and 3 rd postoperative month for scar evaluation. The evaluation was based on different superficial facial wound repairs (i.e., low tension) with an average length <3 cm; and if the surgeon subjectively felt that subcuticular sutures were justified to reduce wound tension, then these were used. Isoamyl 2-cyanoacrylate glue was applied over lacerated wound margins after cleaning the wound and holding together for 15 s by means of tissue holding forceps. Statistical Analysis: Statistical analysis was done using Chi-square test after collection of data. Mean and standard error were estimated from the sample. Results: The mean total time taken for skin closure was 1-2.5 min. There was no wound infection in any of the cases; only one case showed wound dehiscence on 3rd postoperative day. The cosmetic was better as there were no suture marks. Conclusion: Isoamyl 2-cyanoacrylate can be considered as excellent "no needle" alternative for closure of selected pediatric lacerations, those that are short, clean and under low tension. |

Developing a visual rating chart for the esthetic outcome of unilateral cleft lip and palate repair |
p. 55 |
A Olusanya Adeola, A Akadiri Oladimeji DOI:10.4103/2231-0746.161060 PMID:26389035Introduction: Aesthetic impairment is a major concern for the cleft lip/palate patient. Thus, auditing of postsurgical esthetic outcome needs to be further explored as till date no universally accepted protocol exists. The study objective was to propose a new visual rating chart (VRC) for the aesthetic outcome of cleft lip and palate (CLP) surgery. Materials and Methods: In a retrospective review of 200 repaired clefts, the common esthetic deficiencies were identified, categorized and ranked in the order of severity. A chart of the illustrative diagram with textual description of the defects was produced and used as a basis for rating outcome by two groups of raters (familiar raters and recruited raters). Intra- and inter-raters reliability was estimated using Cohen's kappa statistics and intra-class correlation coefficient (ICC). Comparison between mean group coefficient was achieved with Kendall's correlation coefficient of concordance. Results: The intra- and inter-rater reliability for familiar raters was found to be strong with kappa values range of 0.80-0.87 (P < 0.001). Similarly, inter-raters' reliability by recruited judges was very strong using ICC at both single (0.768) and average measures (0.982). Conclusion: The VRC is a reliable tool for assessing the esthetic outcome of CLP repairs. |

Postoperative evaluation of the folded pharyngeal flap operation for cleft palate patients with velopharyngeal insufficiency |
p. 62 |
Hidemi Yoshimasu, Yutaka Sato, Takashi Mishimagi, Akihide Negishi DOI:10.4103/2231-0746.161066 PMID:26389036Background: Velopharyngeal function is very important for patients with cleft palate to acquire good speech. For patients with velopharyngeal insufficiency, prosthetic speech appliances and speech therapy are applied first, and then pharyngeal flap surgery to improve velopharyngeal function is performed in our hospital. The folded pharyngeal flap operation was first reported by Isshiki and Morimoto in 1975. We usually use a modification of the original method. Purpose: The purpose of this research was to introduce our method of the folded pharyngeal flap operation and report the results. Materials and Methods: The folded pharyngeal flap operation was performed for 110 patients with velopharyngeal insufficiency from 1982 to 2010. Of these, the 97 whose postoperative speech function was evaluated are reported. The cases included 61 males and 36 females, ranging in age from 7 to 50 years. The time from surgery to speech assessment ranged from 5 months to 6 years. In order to evaluate preoperative velopharyngeal function, assessment of speech by a trained speech pathologist, nasopharyngoscopy, and cephalometric radiography with contrast media were performed before surgery, and then the appropriate surgery was selected and performed. Postoperative velopharyngeal function was assessed by a trained speech pathologist. Results: Of the 97 patients who underwent the folded pharyngeal flap operation, 85 (87.6%) showed velopharyngeal competence, 8 (8.2%) showed marginal velopharyngeal incompetence, and only 2 (2.1%) showed velopharyngeal incompetence; in 2 cases (2.1%), hyponasality was present. Approximately 95% of patients showed improved velopharyngeal function. Conclusions: The folded pharyngeal flap operation based on appropriate preoperative assessment has been shown to be an effective method for the treatment of cleft palate patients with velopharyngeal insufficiency. |

Usability of surgical treatment in cases of bisphosphonate-related osteonecrosis of the jaw stage 2 with sequestrum |
p. 67 |
Yosuke Fukushima, Yuichiro Enoki, Chieri Nakaoka, Masahiko Okubo, Syoichiro Kokabu, Junya Nojima, Tsuyoshi Sato, Tetsuya Yoda DOI:10.4103/2231-0746.161067 PMID:26389037Objective: This retrospective study was conducted to reveal usability of surgical treatment in the cases of bisphosphonate-related osteonecrosis of the jaw (BRONJ) stage 2 with sequestrum. Patients and Methods: Study subjects included 18 patients having BRONJ stage 2 with sequestrum and 12 non-BRONJ patients with nearly equal clinical states of BRONJ stage 2. Patient characteristics, frequency of inciting factors of osteonecrosis, and treatment results were compared between BRONJ group and non-BRONJ groups. In addition, correlation between treatment methods (conservative therapy, sequestrum curettage, and sequestrectomy) and treatment results and correlation between the administration route of bisphosphonates (BPs) (oral or intravenous) and treatment results were examined statistically. The Student's t-test and Fisher's exact test were performed for statistical analysis. Results: Patient characteristics, frequency of inciting factors of osteonecrosis, and treatment results showed no significant differences between the two groups. In the BRONJ group, treatment result of sequestrectomy was significantly better than conservative therapy/sequestrum curettage (P < 0.001), however, no significant difference was observed in the non-BRONJ group. No significant difference was found in correlation between the administration route of BPs and treatment results in the BRONJ group. Conclusion: Treatment outcome of sequestrectomy was better than conservative therapy/sequestrum curettage in BRONJ stage 2 cases with sequestrum. |

The use of autogeneous mandibular bone block grafts for reconstruction of alveolar defects |
p. 71 |
Doğan Dolanmaz, Alparslan Esen, Gülsün Yıldırım, Özgür İnan DOI:10.4103/2231-0746.161070 PMID:26389038Objective: Purpose of this retrospective study was to evaluate outcomes autogenous bone block grafts obtained from mandible for different indications. The healing of the donor and recipient sites in the postoperative period, morbidity and the resorption of the graft were investigated. Patients and Methods: Twenty-nine patients grafted with mandibular bone block graft were participated in the present study. Grafting was applied in these patients for three indications; reconstruction of alveolar cleft, lateral crest augmentation before dental implantation and sinus floor augmentation. All operations were performed under local anesthesia and in some cases sedation was used as well. Results: Minimal exposure of the block graft occurred in three alveolar cleft patients. Secondary epithelization was achieved in all cleft patients with no symptoms of infection. In one patient infection was seen in donor site 1-week after the operation. The region was curetted and antibiotics administrated again. Two patients showed an infection of recipient site, after 4 weeks the grafts were removed. In all the patients, as the screw head became apparent until 1 thread, amount of the resorption were considered <1.5 mm. Conclusion: The usage of mandibular block grafts is a simple and effective treatment modality for reconstruction of different types of alveolar defects and it also reduces cost of treatment. |

Routine removal of the plate after surgical treatment for mandibular angle fracture with a third molar in relation to the fracture line |
p. 77 |
Kazuhiko Yamamoto, Yumiko Matsusue, Satoshi Horita, Kazuhiro Murakami, Tsutomu Sugiura, Tadaaki Kirita DOI:10.4103/2231-0746.161077 PMID:26389039Purpose: The purpose was to analyze the clinical course of surgically treated mandibular angle fractures from the viewpoint of routine removal of the plate because these fractures are associated with high rates of complications and plate removal. Subjects and Methods: The subjects were 40 patients with unilateral mandibular angle fracture, which was intraorally reduced and principally fixed with a single miniplate on the external oblique ridge. The third molar in relation to the fracture line was extracted in seven patients during the surgery. Clinical course was evaluated in terms of removal of the plate, preservation of the third molar and complications. Results: One patient showed a wound infection postoperatively, and two patients developed pericoronitis during the follow-up. These were managed with medication and local irrigation. One patient with a preserved third molar did not make a required visit and was lost from the follow-up. Removal of the plates was performed in 39 patients after confirmation of good fracture healing, mostly within a year. Twenty-four of 32 preserved third molars were simultaneously extracted. These procedures were generally performed under local anesthesia on an outpatient basis, and they did not cause any complications. Conclusions: Routine removal of the plate after surgical treatment for mandibular angle fractures, simultaneously with extraction of the third molar if indicated, may be beneficial to avoid complications related to the plate and the third molar later in life. |

Repair of segmental bone defects in the maxilla by transport disc distraction osteogenesis: Clinical experience with a new device |
p. 85 |
James Boonzaier, George Vicatos, Rushdi Hendricks DOI:10.4103/2231-0746.161087 PMID:26389041The bones of the maxillary complex are vital for normal oro-nasal function and facial cosmetics. Maxillary tumor excision results in large defects that commonly include segments of the alveolar and palatine processes, compromising eating, speech and facial appearance. Unlike the conventional approach to maxillary defect repair by vascularized bone grafting, transport disc distraction osteogenesis (TDDO) stimulates new bone by separating the healing callus, and stimulates growth of surrounding soft tissues as well. Bone formed in this way closely mimics the parent bone in form and internal structure, producing a superior anatomical, functional and cosmetic result. Historically, TDDO has been successfully used to close small horizontal cleft defects in the maxilla, not exceeding 25 mm. Fujioka et al. reported in 2012 that "no bone transporter corresponding to the (large) size of the oro-antral fistula is marketed. The authors report the successful treatment of 4 cases involving alveolar defects of between 25 mm and 80 mm in length. |

Pedro Henrique de Souza Lopes, Diogo de Oliveira Sampaio, Bruno Luiz de Souza Menezes, Daniel Ferreira do Nascimento, Belmino Carlos Amaral Torres DOI:10.4103/2231-0746.161090 PMID:26389042The oroantral fistula (OAF) is an epithelialized communication between the oral cavity and the maxillary sinus. In most of the cases, this communication occurs after molars and premolars extractions, but other factors may be cause of the communication, such as trauma. This article demonstrates an alternative surgical technique illustrated with a case report in which we perform the surgical treatment of OAF with palatal flap rotation combined with the use of titanium mesh in a victim of gunshot projectile wound in oral cavity. |

Management of nasolacrimal duct injuries in mid-facial advancement |
p. 93 |
SM Balaji DOI:10.4103/2231-0746.161092 PMID:26389043Nasolacrimal duct (NLD) may be injured following trauma. During certain surgical procedure, inadvertent damage to the nasolacrimal apparatus may occur as well. Such instances should be immediately managed to prevent any subsequent complications. The management of such inadvertent injuries may be accomplished only with a thorough anatomic comprehension and surgical expertise in the field of operation. It also requires the presence of armamentarium required for its management in situations when complications arise. The case report discusses one such rare complication of NLD injury during Le Fort III osteotomy and advancement effectively managed by bicanalicular stenting. |

Nonsyndromic palate Synechia with floor of mouth |
p. 100 |
Sharan Naidoo, Kurt W Bütow DOI:10.4103/2231-0746.161102 PMID:26389045To discuss the embryological basis, sequela and management of intraoral synechia, and to report on the incidence of this condition at a facial cleft deformity clinic (FCDC), with specific attention to two rare cases of mucosal bands involving the floor of the mouth and palate. Review of the literature and a retrospective analysis of FCDC and case report of two cases. During the period of 30 years (1983-2013), the FCDC - University of Pretoria has managed in excess of 4000 cases. A review of the clinic statistics revealed only six cases in which intraoral synechiae occurred. The rarity of this condition at the FCDC is in keeping with the rare incidence in the international literature. Four syndromic cases were identified. Three cases were cleft palate lateral synechia syndrome, and one was an orofacial digital syndrome. Two nonsyndromic cases were identified, and both cases involved the floor of the mouth and palate. The attending physicians and surgeons should be aware of the most appropriate timing for management of this condition, in order to avoid unwanted sequelae. Supportive care should be provided, and emergency airway protocol should be available for all cases. A differential diagnosis should be considered which includes syndromic conditions. |

Lingual thyroid |
p. 104 |
LK Surej Kumar, Nikhil Mathew Kurien, MM Jacob, P Varun Menon, Sherin A Khalam DOI:10.4103/2231-0746.161103 PMID:26389046Lingual thyroid is an abnormal mass of ectopic thyroid tissue seen in base of tongue caused due to embryological aberrancy in development of thyroid gland. Most of the ectopic tissue is seen in the tongue.
Their identification and proper management is essential since they may be the only functioning thyroid tissue occurring in the body. We report a case of lingual thyroid in a 40 year old female patient who was hypothyroid with posterior swelling of tongue. Tc-99 scintigraphy confirmed the clinical diagnosis and surgical excision of entire tissue was done by midline mandibular split osteotomy and patient was placed under lifelong thyroxine replacement. Follow up showed excellent results with minimum patient discomfort. |

Esthetic and functional rehabilitation in patients with cleft lip and palate |
p. 108 |
Vasilios A Bousdras, Peter R Ayliffe, Mark Barrett, Colin Hopper DOI:10.4103/2231-0746.161109 PMID:26389047Oral rehabilitation of missing teeth in cleft patients has acceptable success rates. A two-stage approach is indicated; however, timing of implant placement in the grafted maxilla varies within existing protocols. This case highlights successful implant osseointegration and esthetic oral rehabilitation following placement of two implants at 5 months after maxillary grafting (alveolar bone grafting) with a corticocancellous block obtained from the iliac crest. A 31-year-old male patient had already undergone repair of his bilateral cleft lip and soft palate according to established guidelines for cleft patients. Initial closure of his alveolar clefts and further correction of the maxillary hypoplasia with a bi-maxillary osteotomy were completed in 2002. However, bone resorption due to infection in 2003 necessitated removal of all maxillary incisors. The patient was not satisfied with the removable partial denture provided. In 2007, he did undergo anterior maxillary augmentation under general anesthesia, and 5 months later two implants were placed. A 3-unit bridge did replace functional and esthetic demands. Postoperative recovery was uneventful, and overall bone loss, and oral health remain within standards 28 months following implant placement. Optimal outcome is achievable when replacing missing teeth in cleft patients when timing does not exceed approximately a 6-month interval from bone grafting to implant placement. This article demonstrates that overall esthetic and functional rehabilitation is feasible in cleft lip and palate patients. In this patient, overall oral treatment was achieved with an implant prosthesis. |

Nasoalveolar molding in a case of incomplete cleft lip: Is it worth doing? |
p. 112 |
Elçin Esenlik, Mustafa Asim Aydin DOI:10.4103/2231-0746.161112 PMID:26389048The purpose of this study was to evaluate the effects of presurgical nasoalveolar molding in an infant with incomplete cleft lip and alveolar notch. The patient was a 15-day-old female infant with a two-thirds vertical separation of the left side of the upper lip, with an intact nasal sill. A modified molding appliance was made to improve nasal esthetics and correct the alveolar notch. Although the nasal and alveolar region abnormalities were not serious, the molding appliance improved the nasal and lip esthetics and was stable during the 4-year follow-up. |

Echinoccocal cyst affecting the mandible |
p. 115 |
Nitin Bhola, Anendd Jadhav, Rajiv Borle, Samarth Shukla DOI:10.4103/2231-0746.161115 PMID:26389049Echinococcosis is a parasitic infection also called as hydatid disease or hydatidosis. Hydatidosis is a cyclo-zoonotic infection of the larvae form of Echinococcus granulosus (canine tapeworm). The majority of hydatid cysts are seen in the liver (65%) as most of the embryos are trapped within it. Infratemporal region is an unusual site for hydatidosis and has been sparsely reported in the literature. To the best of our knowledge, this is the fourth and perhaps the largest case report of hydatidosis involving the mandible in the literature in right infratemporal region involving the ramus condyle unit in a 35-year-old female with chief complaint of pain on right side of temporomandibular joint area on mastication, and opening and closing of mouth. |

Maxillary adenomatoid odontogenic tumor associated with a premolar |
p. 119 |
Vimal Kalia, Geeta Kalra, Nitin Kaushal, Vikas Sharma, Mayank Vermani DOI:10.4103/2231-0746.161118 PMID:26389050The adenomatoid odontogenic tumor (AOT) represents 3-7% of all odontogenic tumors, and over 750 cases have been reported in the literature. This lesion was formerly considered to be a variant of the ameloblastoma and was designated as adenoameloblastoma. These lesions may infrequently produce dentinoid material and rarely enamel matrix. Consequently, the WHO (2005) classification of odontogenic lesions considered this process to represent a mixed odontogenic neoplasm. We present a case of a 12-year-old female patient with an AOT of diameter 5 cm × 5 cm located in the anterolateral region of the maxilla in association with an impacted premolar tooth. The rarity of AOT, association of this lesion with regards to maxillary premolar, the exaggerated size at presentation, the eruption of the displaced canine postoperatively and uneventful healing of the bony defect without adjunctive therapy makes this case unique. |

Giant complex odontoma in maxillary sinus |
p. 123 |
Adriano Rossini Carvalho Visioli, Cléverson de Oliveira e Silva, Fabiano Carlos Marson, Wilton Mitsunari Takeshita DOI:10.4103/2231-0746.161131 PMID:26389051In this manuscript, we present a rare case report of giant complex odontoma in the maxillary sinus, where the applied therapy included complete excision of the lesion with a conservative approach. Odontomas are also called benign growth abnormalities or hamartomas. They represent a more common type of odontogenic tumor and are related to various disorders such as bad dental placements, expansion, increased volumetric bone, and no eruption of permanent teeth. Usually they have an asymptomatic evolutionary course. The etiologic factors, although obscure, are related to local trauma, infection, and genetic factor. The structural composition of an odontoma consists of mature dental tissues. Odontomas can be differentiated according to their anatomical presentations: Compound odontoma-clusters of several denticles and complex odontoma-well defined tumefaction mass. The diagnosis can be performed by radiographic examination. |

Cementoblastoma of posterior maxilla involving the maxillary sinus |
p. 127 |
Anuj S Dadhich, Kumar Nilesh DOI:10.4103/2231-0746.161135 PMID:26389052Cementoblastoma is a rare neoplasm, representing <1% of all odontogenic tumors. It usually occurs in the posterior mandible and is associated with roots of a mandibular first molar or second premolar. This paper presents a rare case of cementoblastoma in the maxillary posterior region involving the maxillary sinus, in a young female patient. The clinical, radiological, and histopathological features of the lesion are discussed along with a review of previously reported cases in the literature. |

Psammous desmo-osteoblastoma with concomitant aneurysmal bone cyst of mandible |
p. 130 |
SK Shruthi, VV Kamath, Satish Hegde, B Sreevidya DOI:10.4103/2231-0746.161136 PMID:26389053Juvenile psammomatoid ossifying fibroma is a gradually progressive, aggressive extragnathic craniofacial tumor of bone. Due to its complex histogenesis, biological behavior, histology, and classification, its nomenclature has always been the focus of debate among pathologists. Based on the clinical behavior and histology, the term psammous desmo-osteoblastoma (PDO) is an apt expression for this lesion. Immunohistochemical investigation with anti-osteonectin shows positivity for spindle cells whereas psammoma bodies are negative. These results shore up the hypothesis of osteogenic differentiation of the undifferentiated mesenchymal cells of the periodontal ligament that may be responsible for the aggressive behavior of the lesion. Aneurysmal bone cysts (ABCs) are known to be secondarily associated with primary osseous neoplasms like ossifying fibroma, giant cell granuloma, etc. We report a rare case of PDO with concomitant ABC in the mandible of a 30-year-old male patient. The present lesion had recurred at the same site of an osteolytic lesion diagnosed 7 years ago as a benign fibro-osseous lesion and treated by conservative surgical curettage. The histological presentation substantiated by special stains and immunohistochemistry point to the diagnosis of psammous desmo-osteoblastoma with a concomitant ABC. Review of the literature revealed the presentation to be rare with very few cases reported till date. |
