The role of distraction osteogenesis in the management of craniofacial syndromes |
p. 4 |
Andrew A Heggie, Ricky Kumar, Jocelyn M Shand DOI:10.4103/2231-0746.110063 PMID:23662252Distraction osteogenesis (DO) has been established as a useful technique in the correction of skeletal anomalies of the long bones for several decades. However, the use of DO in the management of craniofacial deformities has been evolving over the past 20 years, with initial experience in the mandible, followed by the mid-face and subsequently, the cranium. This review aims to provide an overview of the current role of DO in the treatment of patients with craniofacial anomalies. |

Premaxillary characteristics in complete bilateral cleft lip and palate: A predictor for treatment outcome |
p. 11 |
Marwa Abdelwahab El Kassaby, Noha Ibrahim Abdelrahman, Islam Islam Abbass DOI:10.4103/2231-0746.110064 PMID:23662253Objectives: The aim of the current study was to investigate how bilateral cleft lip and palate (BCLP) cases responded differently to presurgical orthopedics (PSO) and primary lip repair (LR) based on premaxillary characteristics. We suggest a clinically oriented descriptive classification for BCLP based on premaxillary characteristics. Design and Setting: A retrospective longitudinal comparative study where available records of all non-syndromic patients with complete BCLP attending the Cleft Clinic, affiliated to the Oral and Maxillofacial Surgery department, Ain-Shams University, Cairo, Egypt were assessed. Sample Population and Methodology: Twenty-two cases were collected over a 4-years period from 2008 to 2011 (15 boys and 7 girls). Model assessment was performed for serial models representing four stages of treatment; M1: Prior to start of PSO, M2: At the end of PSO, M3: One month after LR, M4: Three months after LR. The premaxillary and vomerine widths were measured on M1. Models (M1-M4) were assessed for changes in anteroposterior projection, anterior arch width, intercanine width and posterior arch width and results were statistically analyzed. Intra-and postoperative surgical findings during and after primary LR were recorded. The sample was divided into two groups based on the premaxillary size and characteristics; Group R: Rudimentary premaxilla and Group P: Prominent premaxilla. Results: There was a highly significant difference in premaxillary width between the two groups ( P = 0.00), changes in anteroposterior projection of the premaxilla were significant one and three months after LR. Changes in maxillary anterior arch width, intercanine and posterior arch widths were non-significant between groups. Mean age difference between the two groups was only statistically significant at the stage of LR. Surgical differences were noted between the two groups. Postoperatively as compared to group R; group P showed more premaxillary bulge and show at rest, as well as more prolabial stretching. In addition, facial profile was more convex in group P. Conclusion: The two types of BCLP outlined in this study are different from several aspects, and hence management should be modified according to each case. This descriptive classification provides a useful tool for evaluation and planning of patients with BCLP. |

Costal cartilage nasal augmentation rhinoplasty: Study on warping |
p. 20 |
SM Balaji DOI:10.4103/2231-0746.110070 PMID:23662254Background: To retrospectively study the costochondral graft (CCG) based nasal dorsum augmentation failures due to warping. Materials and Methods: All patients fulfilling inclusion and exclusion criteria between January 2008 and December 2011 were included in the study. The details of the dorsal nasal length (DNL) immediate postoperative and 1 week postoperative period as well as the degree of divergence from midline by warping noted down in mm along with age, gender, and nature of graft. Statistics: Data analyzed using Statistical Package for the Social Sciences version 17. Descriptive statistics, Chi-square test and one-way analysis of variance are presented. P value ≤0.05 was considered significant. Result: One hundred and fifty seven cases fulfilled the criteria. Of these, 44 (28%) were males and rest were females. The mean age of the patients was 24.41 ± 4.9 years with a range of 17-37 years. In 102 cases (65%) had soft CCG while 55 (35%) were identified to be gritty type of CCG. Of the 157 cases, warping was identified in 41 cases (26.1%) and required revision of the surgery. Age group was significantly associated with presence of warping ( P = 0.000). Discussion: With increase in age, the number of patients with gritty CCG was higher. Older patients had lesser incidence of warping while younger patients had more incidence of warping. The incidence was not significantly related to gender or the DNL. The grafts that were relatively straight had less incidence of warping. |

Fixation of zygomatic and mandibular fractures with biodegradable plates |
p. 25 |
Saikrishna Degala, Sujeeth Shetty, S Ramya DOI:10.4103/2231-0746.110072 PMID:23662255Context: In this prospective study, 13 randomly selected patients underwent treatment for zygomatic-complex fractures (2 site fractures) and mandibular fractures using 1.5 / 2 / 2.5-mm INION CPS biodegradable plates and screws. Aims: To assess the fixation of zygomatic-complex and mandibular fractures with biodegradable copolymer osteosynthesis system. Materials and Methods: In randomly selected 13 patients, zygomatic-complex and mandibular fractures were plated using resorbable plates and screws using Champy's principle. All the cases were evaluated clinically and radiologically for the type of fracture, need for the intermaxillary fixation (IMF) and its duration, duration of surgery, fixation at operation, state of reduction at operation, state of bone union after operation, anatomic reduction, paresthesia, occlusal discrepancies, soft tissue infection, immediate and late inflammatory reactions related to biodegradation process, and any need for the removal of the plates. Statistical Analysis Used: Descriptives, Frequencies, and Chi-square test were used. Results: In our study, the age group range was 5 to 55 years. Road traffic accidents accounted for the majority of patients six, (46.2%). Postoperative occlusal discrepancies were found in seven patients as mild to moderate, which resolved with IMF for 1-8 weeks. There were minimal complications seen and only as soft tissue infection. Conclusions: Use of biodegradable osteosynthesis system is a reliable alternative method for the fixation of zygomatic-complex and mandibular fractures. The biodegradable system still needs to be refined in material quality and handling to match the stability achieved with metal system. Biodegradable plates and screws is an ideal system for pediatric fractures with favorable outcome. |

p. 31 |
Santosh S Gudi, Jagadish Sarvadnya, Neelakamal Hallur, BC Sikkerimath DOI:10.4103/2231-0746.110074 PMID:23662256Background and Objectives: The objective of this study was to evaluate the usefulness of ultrasound guided surgical drainage in submasseteric space abscess of odontogenic origin without incision. Materials and Methods : Eleven patients (4 males and 7 females) aged 18 to 36 years were included in this study. Each patient had clinically and radiologically diagnosed submasseteric space abscesses of odontogenic origin. All the patients underwent ultrasound guided drainage by using 5.7 MHz B-mode, gray scale, ultrasound scanner. The aspirated pus was sent for microbiological culture and sensitivity tests. All the patients were given a prescription of antibiotics like Amoxicillin with Clavulanate in a dose of 625 mg 8 hourly daily, Metronidazole 400 mg 8 h daily and analgesic Diclofenac potassium in a dose of 50 mg 8 h daily. Infection was considered resolving when the following criteria were met like ceased or minimal drainage. Results: There was successful resolution of abscess in 10 cases, 1 case underwent incision and drainage because of spread of infection to other spaces. Conclusion: This study on 11 cases supported ultrasonography as an intraoperative aid in the assessment of the abscess cavity and its real-time imaging facility will help in the location and drainage of the abscess cavity effectively. It avoids large, unsightly, postoperative facial scars and often eliminates the need of general anesthesia and hospitalization. |

Enlarged lymph nodes in head and neck cancer: Analysis with triplex ultrasonography  |
p. 35 |
Vivek Sathyanarayan, K.S.N Siva Bharani DOI:10.4103/2231-0746.110077 PMID:23662257Background: Presence of cervical metastasis is one of the factors influencing the outcome of patients with carcinoma of the head and neck, its early detection is potentially very important. Triplex ultrasonography technology have definitive role in detecting clinically undetectable involvement of lymph nodes (LNs). The purpose of this study was to evaluate, whether triplex ultrasonography characterization of cervical LNs could, with an acceptable degree of certainty, differentiate malignant from benign/reactive LNs, in order to prevent invasive diagnostic procedures. Materials and Methods: A total of 50 patients with oral cancer, were subjected to ultrasonographic investigation of the neck for grayscale, color flow imaging, and pulsed Doppler. All the parameters were compared with histopathologic examination. Correlation was then made between ultrasound and Doppler investigation and histopathology results to evaluate the sensitivity specificity, positive predictive value (PPV) and negative predictive value (NPV) of color Doppler ultrasonography in detecting metastatic neck nodes. Results: Study results showed that malignant LNs, especially metastatic nodes, are accompanied with significantly high resistive index (RI) and pulsatility index (PI) values, rounded shape, size, loss of central hilar echogenicity and peripheral vascularity. Among these sonographic findings, nodal shape (longitudinal nodal diameter to transverse diameter ratio or L/T ratio), RI and PI values were more accurate for differentiating benign from malignant LNs. Conclusion: In this study, triplex sonographic findings had relatively high accuracy in differentiating benign from malignant cervical LNs. Ultrasound hence can be recommended for initial non-invasive evaluation of the neck in patients with oral cancers with or without palpable cervical lymph nodes. |

Residual diplopia in treated orbital bone fractures |
p. 40 |
SM Balaji DOI:10.4103/2231-0746.110078 PMID:23662258Background: Residual diplopia (RD) is the main post-treatment complication of orbital bone fracture (OBF) reduction. The cause of RD is varied and often related to the degree of inflammation, surgical timing, graft requirement, and trauma to orbital musculature, fat, as well as nerves. The exact prevalence of these and the influence of these factors on RD is not widely reported in literature. Materials and Methods: This retrospective study was conducted from January 1, 2000 through December 31, 2011. Sixty nine patients fulfilling inclusion and exclusion criteria were enrolled in this study. The nature of the defect causing RD was identified. Demographics, nature of initial OBF, extent and type of treatment, and grafts were noted. Corrective surgeries were performed. Data entry and analysis were performed using SPSS. Descriptive statistics and Chi square tests were employed. P value ≤ 0.05 was taken as significant. Results: Inferior rectus muscle (71%) and other periorbital musculature (56.5%) was entrapped, leading to RD. Globe position abnormalities was observed in 52.1% of cases. Degree of inflammation, types of grafts (P = 0.000) were significantly related. Discussion: Preoperative swelling, musculature inflammation, and graft placement significantly influenced the surgical outcome of OBF. RD is related to these factors. Adequate control with OBF healing and remodeling needs to be considered while timing OBF. Author's modification with mesh and cartilage in secondary corrective surgery for RD provided an effective solution for immediate intervention. |

Review of secondary alveolar cleft repair |
p. 46 |
Gui-Youn Cho-Lee, Eloy-Miguel García-Díez, Richard-Agostinho Nunes, Carles Martí-Pagès, Ramón Sieira-Gil, Alejandro Rivera-Baró DOI:10.4103/2231-0746.110083 PMID:23662259Introduction: The alveolar cleft is a bony defect that is present in 75% of the patients with cleft lip and palate. Although secondary alveolar cleft repair is commonly accepted for these patients, nowadays, controversy still remains regarding the surgical technique, the timing of the surgery, the donor site, and whether the use of allogenic materials improve the outcomes. The purpose of the present review was to evaluate the protocol, the surgical technique and the outcomes in a large population of patients with alveolar clefts that underwent secondary alveolar cleft repair. Materials and Methods: A total of 109 procedures in 90 patients with alveolar cleft were identified retrospectively after institutional review board approval was obtained. The patients were treated at a single institution during a period of 10 years (2001-2011). Data were collected regarding demographics, type of cleft, success parameters of the procedure (oronasal fistulae closure, unification of the maxillary segments, eruption and support of anterior teeth, support to the base of the nose, normal ridge form for prosthetic rehabilitation), donor site morbidity, and complications. Pre- and postoperative radiological examination was performed by means of orthopantomogram and computed tomography (CT) scan. Results: The average patient age was 14.2 years (range 4-21.3 years). There were 4 right alveolar-lip clefts, 9 left alveolar-lip clefts, 3 bilateral alveolar-lip clefts, 18 right palate-lip clefts, 40 left palate-lip clefts and 16 bilateral palate-lip clefts. All the success parameters were favorable in 87 patients. Iliac crest bone grafts were employed in all cases. There were three bone graft losses. In three cases, allogenic materials used in a first surgery performed in other centers, underwent infection and lacked consolidation. They were removed and substituted by autogenous iliac crest bone graft. Conclusions: The use of autogenous iliac crest for secondary alveolar bone grafting achieves all these several objectives: (1) to obtain maxillary arch continuity, (2) to maximize bone support for the dentition, (3) to stabilize the maxillary segments after orthodontic treatment, (4) to eliminate oronasal fistulae, (5) to provide nasal alar cartilage support, (6) to establish ideal alveolar morphology, and (7) to provide available bone with attached soft tissue for future endosteal implant placement in cases where there is a residual dental space. We advocate for the use of a minimal incision to obtain the iliac crest bone graft and for the use of a corticocancellous block of bone in combination with bone chips. |

Immunohistochemical profiling of Ameloblastomas using cytokeratin, vimentin, smooth muscle actin, CD34 and S100 |
p. 51 |
Herald J Sherlin, Anuja Natesan, Priya Ram, Pratibha Ramani, Chandrasekar Thiruvenkadam DOI:10.4103/2231-0746.110084 PMID:23662260Background: Ameloblastoma is characterized as a slow growing, non-metastatic and a locally invasive tumor with a high risk of recurrence. Immunohistochemical evaluation of ameloblastomas using epithelial and connective tissue specific markers help in studying the histogenesis and assessing the biological behavior. The aim of the study was to study the expression patterns of cytokeratin, vimentin, smooth muscle actin (SMA), S100 and CD34 in ameloblastomas. Materials and Methods: The material for the study consisted of 24 cases of ameloblastomas. The excised specimens were grossed and bits were taken from different areas of the specimen. Based on the histopathology, the cases were classified into different types and stained for immunohistochemistry. Results: The cases showed strong positivity to cytokeratin, vimentin, moderate positivity for SMA and S100. Five cases were also moderately positive for CD34 in blood vessels. Conclusion: The results and hypothesis achieved from the study, proved to be consistent, not only augmenting the already existing hypothesis but also imparting new concepts of hypothesis. |

Gene p63: In ectrodactyly-ectodermal dysplasia clefting, ankyloblepharon-ectodermal dysplasia, Rapp-Hodgkin syndrome |
p. 58 |
Cornelia van Straten, Kurt-W Butow DOI:10.4103/2231-0746.110085 PMID:23662261Introduction: An analysis was made of three different syndromes associated with p63 gene mutations, known as ectrodactyly-ectodermal dysplasia-clefting syndrome (EEC), ankyloblepharon-ectodermal dysplasia clefting syndrome (AEC or Hay-Wells) and Rapp-Hodgkin syndrome (RHS). The postoperative complications associated with their cleft reconstructions were also evaluated. Materials and Methods: Extensive demographic information, in particular of the clinical appearances, associated malformations, and the types and complications of the reconstructive surgical procedures, were recorded of these syndromic cases occurring in a database of 3621 facial cleft deformity patients. The data was analyzed using the Microsoft Excel program. Results: A total of 10 (0.28%) cases of p63 associated syndromes were recorded: EEC (6), RHS (3), and AEC (1). The following clinical cleft appearances were noted - EEC = 6: CLA 1 -right side unilateral (female); CLAP 4 - right side (1) + left side (1) unilateral (male + female); bilateral (2) (males); hPsP 1 (female) (divided in 3 Black, 2 White, 1 Indian); RHS = 3: CLAP 2 (White males); hPsP 1 (White female); AEC = 1: CLAP bilateral (White male). Other features of the syndromes were: skin, hand, foot, tooth, hair and nail involvement, and light sensitivity. Postoperative complications included: (i) stenosis of nasal opening, especially after reconstruction of the bilateral cleft lip and the columella lengthening (2 cases), (ii) premaxilla-prolabium fusion (2 cases), (iii) repeated occurrence of oro-nasal fistula in the hard palate (4 cases), and (iv) dysgnathial development of midfacial structures (3 cases). Discussion: Three different p63 associated syndromes (EEC, AEC, and RHS) were diagnosed (0.27% of the total facial cleft deformities database). The majority of the cases presented with a bilateral CLAP in males only. A number of females and males had unilateral CLA. The hPsP-cleft was recorded in females only. The associated ectodermal component most probably had a profoundly negative influence on postoperatively wound healing, which was observed in particular at the nasal openings, the premaxilla sulcus and in the hard palate mucosa. The reconstruction of p63 associated syndromes is a greater challenge than the usual cleft reconstruction to the surgeon. |

Craniosynostosis: Esthetic protocol in open technique |
p. 62 |
Ghali E Ghali, George Zakhary DOI:10.4103/2231-0746.110086 PMID:23662262Introduction: The past two decades have seen advances relative to the treatment of patients with craniosynostosis in the areas of resorbable fixation, imaging, and both intraoperative and perioperative management. The purpose of this study is to present open cranial vault reshaping techniques and anesthetic protocol used at Louisiana State University Health - Shreveport, USA. Materials and Methods: The surgical procedure of choice was single-stage open cranial vault reshaping with barrel-staving and orbital bandeau advancement as needed for supra-orbital rim deficiencies. Results: The outcomes of single-stage cranial vault reshaping with selective postoperative dynamic orthotics yielded symmetrical and consistent clinical results with only three children out of over 100 cases requiring later surgical correction. Discussion: Our review of techniques provides a safe protocol for management of craniosynostosis with symmetrical clinical head shape. The techniques presented here are aimed at improving the multidisciplinary management of these patients. |

Craniofacial fibrous dysplasia: Surgery and literature review  |
p. 66 |
Suresh Menon, Srihari Venkatswamy, Veena Ramu, Khurshida Banu, Sham Ehtaih, Vinay M Kashyap DOI:10.4103/2231-0746.110088 PMID:23662263Objective: To highlight the clinical and radiologic features and management of craniofacial fibrous dysplasia with review of literature. Materials and Methods: A retrospective review of 6 patients who underwent surgical treatment in a tertiary healthcare centre was done using the parameters of patients' details, clinical features, radiological findings, management and postoperative review. Results: Of the six patients, 3 females and 2 males were in the 2 nd decade of life and 1 male in the 1 st decade of life. The disease was restricted to maxilla in 3 patients, involved the temporal and frontal bones in addition to maxilla in one, involved the frontal bone in one patient and involved frontal and parietal bones in one patient. The primary reason for seeking treatment in all the 6 cases was facial deformity. There was absence of pain in all 6 cases. For surgical treatment in all three cases involving the maxilla, the approach was intraoral while bicoronal approach was used for the other three cases. Treatment consisted of surgical contouring and reshaping the area. All cases were followed up over a period of 2 years with no signs of recurrence. Conclusion: Treatment of craniofacial fibro-osseous lesions is highly individualized. Most cases of craniofacial fibrous dysplasia manifest as swellings that cause facial deformity and surgical recontouring after cessation of growth seems to provide the best results. |

Microsurgical free flaps: Controversies in maxillofacial reconstruction |
p. 72 |
Rinku K George, Arvind Krishnamurthy DOI:10.4103/2231-0746.110059 PMID:23662264Reconstructive microsurgery for oral and maxillofacial (OMF) defects is considered as a niche specialty and is performed regularly only in a handful of centers. Till recently the pectoralis major myocutaneous flap (PMMC) was considered to be the benchmark for OMF reconstruction. This philosophy is changing fast with rapid advancement in reconstructive microsurgery. Due to improvement in instrumentation and the development of finer techniques of flap harvesting we can positively state that microsurgery has come of age. Better techniques, microscopes and micro instruments enable us to do things previously unimaginable. Supramicrosurgery and ultrathin flaps are a testimony to this. Years of innovation in reconstructive microsurgery have given us a reasonably good number of very excellent flaps. Tremendous work has been put into producing some exceptionally brilliant research articles, sometimes contradicting each other. This has led to the need for clarity in some areas in this field. This article will review some controversies in reconstructive microsurgery and analyze some of the most common microvascular free flaps (MFF) used in OMF reconstruction. It aims to buttress the fact that three flaps-the radial forearm free flap (RFFF), anterolateral thigh flap (ALT) and fibula are the ones most expedient in the surgeon's arsenal, since they can cater to almost all sizeable defects we come across after ablative surgery in the OMF region. They can thus aptly be titled as the workhorses of OMF reconstruction with regard to free flaps. |

TMJ imaging by CBCT: Current scenario |
p. 80 |
Bhuvana Krishnamoorthy, NS Mamatha, Vinod AR Kumar DOI:10.4103/2231-0746.110069 PMID:23662265Radiographic examination forms an integral component of the clinical assessment routine in patients with temporomandibular joint disorders (TMJ). There are several imaging modalities to visualize the TMJ. Cone beam computed tomography (CBCT) is a developing technique that is being increasingly used in dentomaxillofacial imaging due to its relatively low-dose high-spatial-resolution characteristics. Research in TMJ imaging has been greatly inspired by the advent of CBCT. In this paper we aim to discuss the present scenario of the role of CBCT in TMJ imaging. |

Cleft palate in Williams syndrome |
p. 84 |
Scopelliti Domenico, Cipriani Orlando, Fatone Flavia Maria Graziana, Piero Papi, Amodeo Giulia DOI:10.4103/2231-0746.110071 PMID:23662266Williams-Beuren syndrome (WBS) is a genomic neurodevelopmental disorder, estimated to occur in approximately 1 in 10,000 persons. It is caused by a deletion of the "elastin" gene on chromosome 7q11.23 and was described officially in 1961 by Williams, Barrat-Boyes, and Lowe. Cleft palate is not considered in the medical literature as a part of the multisystem disorders of the Williams syndrome but it was yet described. We present our experience of a patient who presents cleft palate among other congenital malformations. |

Degloving facial injury treated with hydroconductive dressing |
p. 87 |
Colin Perumal, Michael Bouckaert, Martin Robson DOI:10.4103/2231-0746.110073 PMID:23662267Complex, open maxillofacial fractures are often accompanied by extensive contamination, crush, or avulsion of the overlying soft tissue, there have been two alternatives to treatment: either radical debridement of all contaminated tissue, fixation of the underlying fractures, and soft tissue closure by pedicle flap or graft is done; or more conservative debridement is repeated multiple times until the contaminated tissue is removed and fracture fixation is deemed safe. Debridement is usually accomplished by sharp debridement or with high-pressure intermittent irrigation or some combination of both modalities. The problems with this standard treatment in the face are that facial features may be distorted, superficial branches of the facial and/or trigeminal nerve can be inadvertently sacrificed (even with the use of nerve stimulators), and scarring can distort contours and radically change facial appearance. A serious facial degloving injury with necrotic malodorous tissue and no clear anatomical delineations demanded special attention. The purpose of this report is to demonstrate the management of a soft tissue avulsive contaminated injury of the face with underlying maxillofacial fractures. |

Ectopic tooth in maxillary sinus: Case series |
p. 89 |
Shandilya Ramanojam, Rajshekhar Halli, Manjula Hebbale, Smita Bhardwaj DOI:10.4103/2231-0746.110075 PMID:23662268Ectopic eruption of a tooth within the dentate region of the jaws is often noticed in clinical practice and is well documented in the literature. But the ectopic eruption into the non dentate region is rare and scantly documented. The maxillary sinus is one such a non dentate region, apart from nasal septum, mandibular condyle, coronoid process and the palate, to accommodate such ectopic eruptions of teeth. Due to its rarity and lack of consensus over its management, the incidence deserves to be added to the literature and discussed. Early surgical intervention for removal of ectopic tooth along with enucleation of the associated cyst, if any, is the treatment of choice. |

Burried broken extraction instrument fragment |
p. 93 |
SM Balaji DOI:10.4103/2231-0746.110076 PMID:23662269Despite adequate effort to perform tooth removal carefully, some accidents may happen when defective instruments are unknowingly used. This article reports of a non-symptomatic case of a retained fractured dental elevator tip during an uneventful extraction a decade earlier. Patient was not aware till routine radiographic examination revealed its presence. Use of three dimensional imaging techniques in this case is highlighted. Rarely, instruments breakage may occur during surgical procedures. It is duty of the dentists to check the surgical instrument for signs of breakage and be prepared to solve a possible emergency. Retained fragments should be carefully studied prior to attempt of removal. |

p. 95 |
Dwarkadas Gokuldas Adwani, Rajender Singh Arora, Anirudh Bhattacharya, Bhushan Bhagat DOI:10.4103/2231-0746.110079 PMID:23662270Non-Hodgkin's Lymphoma (NHL) are a group of neoplasms that originate from the cells of the lymphoreticular system. Forty percent of Non-Hodgkin's lymphoma arises from extranodal sites. The nasal cavities and paranasal sinuses are rarely affected by primary NHL. Common primary extranodal sites of lymphomas include stomach, liver, soft tissue, dura, bone, intestine and bone marrow. Most patients present with rapidly enlarging masses, often with symptoms both locally and systemically (fever, recurrent night sweats, or weight loss). The vast majority of patients with localized disease are curable with combined modality therapy or combination chemotherapy alone. About 50% patients are cured with doxorubicin based combination chemotherapy and rituximab. An atypical case of extranodal Non-Hodgkin's lymphoma of maxillary sinus is discussed. |

Swelling on lower lip…not always a mucocele !!! |
p. 98 |
Santosh S Gudi, BC Sikkerimath, RS Puranik, Snehal S Kasbe DOI:10.4103/2231-0746.110080 PMID:23662271Schwannomas are well characterized uncommon neural neoplasms which may rarely present with variation in clinical manifestation. Oral Schwannomas clinically simulate other lesions like traumatic fibroma, pyogenic granuloma, mucocele and salivary gland lesions. The diagnosis of schwannoma is typically made at the time of surgery following biopsy and surgical resection is the mainstay of treatment with no chances of recurrence as they are well encapsulated. We present a case of schwannoma of lower lip occurring in a 21-year-old female patient. |

Psammomatoid type juvenile ossifying fibroma of mandible |
p. 100 |
Ravi S Patil, Chitra Chakravarthy, Sanjay Sunder, Ravi Shekar DOI:10.4103/2231-0746.110081 PMID:23662272Juvenile ossifying fibroma (JOF) is a rare fibro-osseous neoplasm that arises within the craniofacial bones in individuals under 15 years of age, and these lesions are usually benign and tend to grow slowly. The psammomatous type of juvenile ossifying fibroma (PsJOF) mainly involves the bones of the orbit and paranasal sinuses, whereas the trabecular type commonly involves the jaws. We are presenting a case of PsJOF of ramus of mandible in a 7-years-old boy, which is an uncommon condition, and histologically showed predominantly a cellular connective tissue stroma, composed of numerous spindle-shaped cells arranged in fascicular storiform pattern. In between these irregular strands of trabeculae with plump osteoblast, spheroidal ossicles with basophilic in center and eosinophilic in periphery resembling psammoma-like bodies are noticed. |
