Vermilion lower lip cross flap - An anatomic study on 22 fresh cadavers |
p. 107 |
Saeedeh Khajeh Ahmadi, Amin Rahpeyma, Hamed Nemati Rezvani DOI:10.4103/2231-0746.101327 PMID:23483077Context: Vermilion lower lip cross flap is indicated for reconstruction of upper lip in residual deformities following trauma or cleft lip. Flap survival depends on incorporation of inferior labial artery in pedicle. Aims: This article reports measurement of vertical distance between inferior labial artery and vermilion surface under light microscope in midline sagittal cross-sectional specimens harvested from 22 fresh male cadavers, to design cross lip vermilion flap more accurately and reduce morbidity of donor site. Settings and Design: This study is designed to measure vertical distance between uppermost parts of inferior labial artery to vermilion surface in 22 fresh male cadavers. Tissue specimens were taken from lower lip midline in sagittal plane. Histological sections stained with Hematoxylin-eosin were reviewed by Pathologist. Materials and Methods: Measurements were done by staged micrometer which was calibrated in 10 μm subdivisions under light microscope. Vertical distance was measured in millimeter and artery location was defined as submucosal, in superficial muscle and deep muscular layer. Statistical Analysis Used: Descriptive study. Results: Analysis of data shows that mean distance was 2.42 ± 1.67 mm. In 77.27% of cases, the artery was in submucosal layer and in 13.64% of cases this artery was located in superficial muscular layer. Conclusions: As a result 4-mm depth incision of lower lip vermilion that incorporate superficial layer of orbicularis oris muscle will ensure blood supply of lower lip vermilion cross flap. |

Management of obstructive sleep apnea in pediatric craniofacial anomalies |
p. 111 |
Adi Rachmiel, Omri Emodi, Dror Aizenbud DOI:10.4103/2231-0746.101329 PMID:23483041Introduction: Obstructive sleep apnea (OSA) is often associated with congenital craniofacial malformations such as Pierre-Robin Syndrome, Hemifacial Microsomia, Treacher Collins Syndrome resulting in decreased pharyngeal airway, which, in severe cases, leads to tracheostomy dependence. Some pediatric patients had tracheostomies done and others with severe respiratory distress were considered tracheostomy candidates. Materials and Methods: Twelve patients with severe respiratory distress without tracheostomy and ten patients with tracheostomy were treated by mandibular distraction osteogenesis using either external or internal devices. The expansion of mandibular framework was analyzed using bony cephalometric landmarks and computed tomography (CT). Results: The results demonstrated average mandibular elongation of 29 mm on each side using the external devices and 22 mm using the internal devices, and an increase in mandibular volume and pharyngeal airway. The group of patients with tracheostomies were decannulated and in the patients with respiratory distress there was improved airway with improvement of signs and symptoms of OSA with elimination of oxygen requirement. Conclusions: Mandibular distraction is a useful method in younger children with OSA expanding the mandible and concomitantly advancing the base of tongue and hyoid bone increasing the pharyngeal airway. The external devices permit greater distraction length, the removal is simple but the devices are uncomfortable for the patients. On the other hand, the internal devices are more comfortable for patients but permit shorter distraction length and require a second operation for removal. |

The effects of face mask therapy in cleft lip and palate patients |
p. 116 |
Servet Dogan DOI:10.4103/2231-0746.101332 PMID:23483763Background and Aim: Children treated with cleft lip and palate often develops mid-facial retrusion. In this study 20 patients with unilateral cleft lip and palate (UCLP) were treated with face mask and studied for the effect of growth. Materials and Methods: The patients were treated by the same orthodontist using the same techniques and appliances. Mean pre- and posttreatment ages were 8.7 and 9.5 years, respectively. Each child was matched by ethnicity, age, sex, and the SN/MP angle to an untreated (noncleft) control. The treatment period with face mask was approximately 7 months and 5 days. Result: The study showed definite protraction of the maxilla for UCLP group (P < 0.001). The posterior maxilla of the UCLP group underwent anterior displacement while the maxillary incisors showed greater anterior movement than expected for untreated control group (P < 0.01). Vertical changes of the maxilla showed no significant differences in cleft group. The mandible of the UCLP group was rotated inferiorly and posteriorly (P < 0.05) while control group showed inferior and anterior changes. The lower incisors were stable in the two groups. Conclusion: From this study, it can be inferred that the UCLP group show significantly anterior maxillary movements when compared with the control group when face mask is used as per prescription. |

p. 121 |
LB Lahiru Prabodha, Dayanath Kumara Dias, B Ganananda Nanayakkara, Deepthi C de Silva, N Vishvanath Chandrasekharan, Isurani Ileyperuma DOI:10.4103/2231-0746.101334 PMID:23483617Background: Cleft palate is the commonest multifactorial epigenetic disorder with a prevalence of 0.43-2.45 per 1000. The objectives of this study were to evaluate the clinical features and identify the 22q11.2 deletion in patients with cleft palate in Sri Lanka. Materials and Methods: Cleft patients attending a Teaching Hospital in Sri Lanka were recruited for this study. The relevant data were obtained from review of case notes, interviews, and examination of patients according to a standard evaluation sheet. Quantitative multiplex polymerase chain reaction (PCR) was performed to identify the 22q11.2 deletion. A gel documentation system (Bio-Doc) was used to quantify the PCR product following electrophoresis on 0.8% agarose gel. Results and Conclusion: There were 162 cleft palate patients of whom 59% were females. A total of 92 cleft palate subjects (56.2%) had other associated clinical features. Dysmorphic features (25.27%) and developmental delays (25.27%) were the commonest medical problems encountered. The cleft was limited to the soft palate in 125 patients, while in 25 patients it involved both the hard and the soft palate. There were seven subjects with bifid uvula and five subjects with submucous cleft palate. None of the patients had 22q11.2 deletion in this study population. A multicentered large population-based study is needed to confirm the results of this study and to develop guidelines on the appropriate use of 22q11.2 deletion testing, which are valid for cleft palate patients in Sri Lanka. |

Treatment of maxillary cleft palate: Distraction osteogenesis vs. orthognathic surgery |
p. 127 |
Adi Rachmiel, Michal Even-Almos, Dror Aizenbud DOI:10.4103/2231-0746.101336 PMID:23483803Purpose: The purpose of this paper is to compare the treatment of hypoplastic, retruded maxillary cleft palate using distraction osteogenesis vs. orthognathic surgery in terms of stability and relapse, growth after distraction and soft tissue profile changes.th Materials and Methods: The cleft patients showed anteroposterior maxillary hypoplasia with class III malocclusion and negative overjet resulting in a concave profile according to preoperative cephalometric measurements, dental relationship, and soft tissue analysis. The patients were divided in two groups of treatment : S0 eventeen were treated by orthognathic Le Fort I osteotomy fixed with four mini plates and 2 mm screws, and 19 were treated by maxillary distraction osteogenesis with rigid extraoral devices (RED) connected after a Le Fort I osteotomy. The rate of distraction was 1 mm per day to achieve Class I occlusion with slight overcorrection and to create facial profile convexity. Following a 10 week latency period the distraction devices were removed. Results: In the RED group the maxilla was advanced an average of 15.80 mm. The occlusion changed from class III to class I. The profile of the face changed from concave to convex. At a 1-year follow up the results were stable. The mean orthognathic movement was 8.4 mm. Conclusion: In mild maxillary deficiency a one stage orthognathic surgery is preferable. However, in patients requiring moderate to large advancements with significant structural deficiencies of the maxilla or in growing patients the distraction technique is preferred. |

Cleft palate repair in Mongolia: Modified palatoplasty vs. conventional technique |
p. 131 |
N Ayanga Gongorjav, Davaanyam Luvsandorj, Purevjav Nyanrag, Ariuntuul Garidhuu, E Gardiner Sarah DOI:10.4103/2231-0746.101337 PMID:23482408Context: Cleft palate repair is preferentially completed between 6 and 18 months of age, facilitating essential speech and language development along with swallowing and feeding reflexes, and avoiding otitis media and hearing loss. In Mongolia patients often present in early adulthood for cleft lip and/or palate management. Wider defects are associated with older age groups and have higher rates of fistula formation and wound dehiscence. These complications encouraged a modified surgical technique for improved outcomes. Aims: Objectives of this study were to compare the efficacy of three established palatoplasty techniques with our mongolian technique. Materials and Methods: A retrospective review of all palatoplasty cases, in non-syndromic cleft lip and/or palate patients, between January 1992 and November 2008 in Ulaanbaatar, Mongolia was performed. Exclusion criteria included those suffering from an acute or chronic respiratory illness at presentation or in the recovery period. We compared three established techniques with our modified technique. Outcome measures were duration of surgery, length of hospital stay and fistula rate. Statistical Analysis Used: Discrete data are reported as n (%), while continuous data are summarised as meanSD. Differences in demographic, surgical and postoperative data were tested by independent t-test (continuous data) and Fisher's exact test (discrete data). Results: Palatoplasty was performed on 436 patients with an average age of 60 months. The modified palatoplasty technique had reduced surgical time (P value <0.01) and hospital stay (P value <0.01) and a 96% complication free wound recovery, compared with established techniques. Cleft lip and/or palate patients aged 42 months or older were more likely to be from the countryside. Conclusions: 86.9% of patients presenting for cleft palate repair had palatoplasty later than the recommended age. Geographical predilection for children older than six years, were more likely to have cleft palate repair complications. We have shown the modified palatoplasty technique is a more efficient time saving surgical procedure with lower complication rates. |

p. 136 |
Girish B Giraddi, Moinuddin K Syed DOI:10.4103/2231-0746.101338 PMID:23482434Background: Injuries in the orbital region have profound functional as well as aesthetic implications. Treatment of orbital fractures remains one of the most controversial issues in maxillofacial trauma with regard to the classification, diagnosis, surgical approach and treatment. Purpose: This study evaluated and compared the efficacy of two most commonly applied approaches the preseptal transconjunctival with lateral canthotomy and the subciliary approach for the treatment of infraorbital floor and rim fractures. Patients And Methods: Twenty patients reported to G.D.C.R.I. Bangalore who suffered infraorbital floor and rim fractures, were randomly divided into two groups with 10 patients in each group. In one group, anatomic reduction and reconstruction was done with preseptal transconjunctival approach with lateral canthotomy and in the other group with subciliary approach. Results: In transconjunctival group, transient entropion was significant (30%). In subciliary group, transient ectropion was significant (30%). Conclusion: In our study, preseptal transconjunctival approach with lateral canthotomy and subciliary skin-muscle flap approach for the open reduction and rigid fixation of infraorbital floor and rim fractures had showed less morbidity and lesser risk of complications and given satisfactory results. |

p. 141 |
Anshul Rai DOI:10.4103/2231-0746.101339 PMID:23482969Purpose: The purpose of this study was to compare the functions of the condyle and complications after fixation of a subcondylar fracture of the mandible with two noncompression miniplates and a single non-compression miniplate. Materials and Methods : A total of 30 patients who required open reduction of a subcondylar fracture of mandible were selected for the study. The patients were randomly divided into two groups of 15 each. Group I comprised of patients treated with a single miniplate and Group II were treated with two noncompression miniplates. The patients were assessed for malocclusion, lateral deviation on opening, infection, plate removal, facial nerve function, the time taken in the surgery, and cost of implants used, in both the groups. All the parameters were compared statistically using the chi square test. Results: Out of 30 patients, inadequate reduction was noticed in one patient in Group I. Screw loosening occurred in two cases; both the cases were stabilized with a single miniplate. Screw loosening was always associated with chronic infection. In these cases, hardware removal was performed. Plate bending was observed in one case that was stabilized with a single miniplate. Malocclusion and lateral deviation occurred in this case. When two miniplate were used, no plate bending or screw loosening was observed. Malocclusion was observed in Group II. Conclusion: Two plates for subcondylar fractures represent the best solution to obtain stable osteosynthesis in comparison to a single miniplate. |

Long-term follow-up of tibial bone graft for correction of alveolar cleft |
p. 146 |
Hamad Al Harbi, Ahmed Al Yamani DOI:10.4103/2231-0746.101341 PMID:23482654Aims: The aim of this prospective study was to evaluate the quality and stability of autogenous tibial bone graft for the correction of alveolar bone defects in cleft patients in a long-term study as well as to evaluate the postoperative morbidity and risk of complications. Materials and Methods: A total of 47 patients with 55 donor sites were involved in this study. The first author performed all the procedures from 2003 to 2011. Medial and lateral approaches were used to harvest the bone with standardized surgical technique. Evaluation in both donor and recipient sites was done by clinical examination, postoperative pain and recovery, and radiographic examination by Panoramic and occlusal X-rays and lateral X-ray for the tibia. Moreover, the donor site was assessed for functionality and mobility based on the Lysholm score. Finally, the patient's experience was evaluated subjectively utilizing a visual analog scale. Results: The surgical outcome was satisfied in all except two cases with total graft resorption for unknown reasons. Regarding the postoperative patient experience we found that patients experienced pain in the recipient site more than they did at the donor site at 24-hour and two-week follow-ups. Conclusion: We conclude that the proximal tibia is a safe site from which cancellous bone graft can be harvested to repair the alveolus as it carries less early and late morbidity. Thus, we suggest that the tibia is an excellent choice as a donor site for alveolar bone grafting in children and adult with cleft lip and palate with satisfactory long-term stability. |

Cleft lip and palate surgery: 30 years follow-up |
p. 153 |
Cesar A Guerrero DOI:10.4103/2231-0746.101342 PMID:23483117Ten cleft lip and palate patients with complete unilateral (five patients) and bilateral (five patients) clefts were treated by a multidisciplinary team integrated by psychologists, surgeons, orthodontists, prosthodontists, pediatric dentists, and speech pathologists, to obtain ideal soft tissue and hard tissue continuity, facial symmetry, functional and esthetic dentitions, excellent nasal architecture, subtle, and hidden lip scars. No hypernasality and adequate social adaptation were found in the 30 years follow-up (20-30 years follow-up with an average of 25.5 years). The patients were treated in a pro-active fashion avoiding complications and related problems, executing the ideal surgical, dental, and speech therapy plan, based on a close follow-up over the entire period. Those patients treated at the right time required less surgeries and less salvaging maneuvers and presented complete dentitions with less dental prosthesis or dental implants and stable occlusions, than those who missed the ideal dental and surgical treatment opportunities. The focus of this article is the need of a close long-term follow-up to ensure an ideal patient's quality of life. |

Dental maturation of unilateral cleft lip and palate |
p. 158 |
Elaine Li Yen Tan, Mimi Yow, Meaw Charm Kuek, Hung Chew Wong DOI:10.4103/2231-0746.101345 PMID:23483778Cleft lip and palate (CLP) is the most common craniofacial abnormality and the fourth most common birth defect in Singapore. Many reports suggest that CLP children have delayed dental development and asymmetrical timing of tooth-pair formation. The aim of this study was to investigate the timing of development of permanent teeth in unilateral CLP (UCLP) children and to compare the findings with non-CLP children in Singapore. A total of 60 UCLP children aged between 5 and 9 years (mean 6.64 ± 0.90 years) and a non-CLP control group matched for age, gender, and race were investigated and compared. Dental records and radiographs were studied and the dental maturation was determined using the Demirjian's method (1973). The dental maturation of UCLP children were delayed compared with non-CLP children by a mean of 0.55 ± 0.75 years and the delay was statistically significant (p < 0.001). The UCLP group also had significantly higher risk of asymmetrically developing tooth pairs than the control group (p < 0.001). The most commonly delayed tooth in development was the maxillary cleft-sided lateral incisor. In conclusion, the UCLP children in Singapore demonstrated delayed dental maturation and a higher occurrence of asymmetrical tooth-pair formation than the non-CLP children. |

Prevention of oro-facial clefts in developing world |
p. 163 |
Fadekemi O Oginni, Anthony T Adenekan DOI:10.4103/2231-0746.101346 PMID:23482510Oro-facial cleft (OFC) remains a prominent health issue in developed and developing countries alike. It is the commonest craniofacial birth defect in humans. Mounting evidence suggest a polygenic, multifactorial and a list of epigenetic events. Primary prevention of OFC is based on recognition of the etiologic and risk factors. While a number of preventive strategies are in place for OFC in most developed countries of the world, the majority of developing countries are distant from achieving this goal for a number of reasons. Notable among these are a huge knowledge and practice gap in the field of genetics and dearth of accurate data. In addition, improper coordination and absenteeism from antenatal care contributed greatly to this set back. With ongoing efforts aimed at determining the genetics of nonsyndromic OFC in developing countries, researches directed at identifying environmental factors should equally be in place. Pending the outcome of these, implicated environmental and attitudinal risk factors in other populations could serve as preventive template in health education and interventions. Since risk factors vary between populations, definitive and effective preventive strategies and models would vary from place to place and from time to time. Frantic effort directed at identifying specific implicated risk factors in developing countries should include developing and keeping comprehensive national perinatal database and centralization of antenatal care protocol. Additionally, active health education at every level and a focus on developing manpower in the field of genetics should be in place. These would be designed and tailored toward identified, proven, and emerging risk factors. |

Modified facial bipartition |
p. 170 |
SM Balaji DOI:10.4103/2231-0746.101348 PMID:23483335Orbital hypertelorism is a craniofacial abnormality that arises on its own or as part of a number of syndromes. It is not uncommon to find the condition in association with maxillary hypoplasia. This manuscript reports an uncommon case of Tessier 2, 12 with orbital hypertelorism and dentoskeletal maxillary prognathism. To correct the condition, the first stage procedure was a modification of facial bipartition, according to the need of the case, followed by correction of alar cleft by Denonvilliers technique. |

Khurshida Banu, Mohammed Ehtaih Sham, Sri Hari, Veena Sharad DOI:10.4103/2231-0746.101352 PMID:23482322The Aneurysmal bone cyst (ABC) is an infrequent but well defined lesion occurring most commonly in the long bones, the pelvis and vertebrae. Only 1-2% of the lesions are known to occur in the maxillofacial region. Clinically, the lesion usually occurs in young adults below 20 years of age. Though there does not seem to be any marked gender predilection and slight preponderance towards females has been reported. Here we present a case of giant recurrent aneurysmal bone cyst in a 19 year old male patient treated by segmental resection and reconstruction with vascularized fibular graft. |

Ajaz Shah, Suhail Latoo, Irshad Ahmed, Altaf H Malik, Shahid Hassan, Abraar Bhat, Shazia Mir, Nitul Jain DOI:10.4103/2231-0746.101358 PMID:23483745Segmental odontomaxillary dysplasia (SOD) is a rare developmental disorder of the maxilla, characterized by variability of its clinical and radiological features and may mimic other fibro-osseous lesions. Clinically, the disorder is often diagnosed in early childhood due to a unilateral buccolingual expansion of the posterior alveolar process, gingival enlargement, absence of one or both premolars in the affected region, delayed eruption of the adjacent teeth, and malformations of the primary molars. We describe a rare case of a SOD in a 19-year-old female comprising findings similar to earlier reports, but for the first time SOD is reported along midline. She presented with pre-maxillary enlargement and abnormal pattern of eruption of anterior maxillary permanent teeth. Radiographic imaging showed abnormal bony trabeculation. Histopathologic findings showed characteristic features of SOD. We herein report a case of this rare unusual anomaly and review the literature. Clinicians should be aware of its presence when encountering patients presenting with facial asymmetry unresponsive to treatment. |

SM Balaji DOI:10.4103/2231-0746.101363 PMID:23483013Congenital diffuse infiltrating lipomatosis of the face (CDIL-F) is a rare pathological entity belonging to the subgroup of lipomatous tumors. Till date only a handful of cases has been documented and known to occur exclusively in infancy. On microscopical examination, it is characterized by diffuse infiltration of mature adipose tissue over normal muscle fibers, rapid growth, associated osseous hyperplasia, and a high recurrence rate after surgical intervention. An attempt has been made to identify and characterize all the 49 documented cases of CDIL-F in literature along with describing a report of a male child with CDIL-F. Follow-up of 8 years has been documented. The pathogenesis and spectrum of treatment modality are discussed with identified clinical features. |

Orbital hydatid cyst |
p. 197 |
Header D Al-Muala, Suha M Sami, Mahamoud A. R. Shukri, Header K Hasson, Abbas T Alaboudy DOI:10.4103/2231-0746.101365 PMID:23483684Hydatid cysts rarely appear isolated in the orbital cavity without involvement of other organs. Most of these are situated in the superolateral and superomedial angles of the orbit. Inferiorly located cysts are very uncommon. The authors report a case of a primary hydatid cyst of the orbit with inferiolateral localization. The cyst was enucleated surgically via a rhinotomy approach. This case was considered as a primary infection, because there was no previous history of hydatid disease and no findings of liver and lung cysts on radiological examination. Physicians should include orbital hydatid cyst in the differential diagnosis of unilateral proptosis. To avoid complications that might occur during surgery, the cyst can be easily removed using a gentile enucleation technique. |

KV Arunkumar, Sanjeev Kumar, Rajat Aggarwal, Prajesh Dubey DOI:10.4103/2231-0746.101367 PMID:23482828The use of firearms is becoming more prevalent in the society and hence the number of homicidal and suicidal cases. The severity of gunshot wounds varies depending on the weapons caliber and the distance of firing. Close-range, high-velocity gunshot wounds in the head and neck region can result in devastating esthetic and functional impairment. The complexity in facial skeletal anatomy cause multiple medical and surgical challenges to an operating surgeon, demanding elaborate soft and hard tissue reconstructions. Here we present the successful management of a patient shot by a low-velocity short-range pistol with basic life support measures, wound management, reconstruction, and rehabilitation. |
