ABSTRACT
Condylar hyperplasia is a rare pathology characterised by excessive bone growth that presents virtually unilaterally, resulting in facial asymmetry. The aetiology of this disorder is not well understood. This pathology has been reported to be a rare entity with very few cases being reported in the literature, mostly seen between 11 and 30 years of age, with males and females being equally affected and having no predominance to the left or right side. It has also been reported to be a self-limiting condition, that is, the active growth can cease at any point in time. We report two cases of unilateral condylar hyperplasia in 24- and 19-year-old male and female patients, where the first was treated by condylectomy and BSSO, and the latter was treated by high condylectomy and recontouring of the mandible.
ABSTRACT
Surgical reconstruction of the missing external ear is difficult, and the results are often far from satisfactory. An implant-retained auricular prosthesis is a suitable alternative. Microtia, malformation, deformity, and partial or complete loss of the external ear may be due to various congenital or acquired factors. A case series of three patients treated with implant-retained auricular prostheses is presented in this article. For each missing pinna, two titanium implants were placed in the temporal bone. After 6 months of osseointegration, the implants were loaded. All three cases were rehabilitated with a bar and clip retained prosthesis. There were two male and one female patient with an average age of 16.6 years. One patient had unilateral absence of external ear and two had bilateral absence. A total of 10 implants were placed, 4 on the right side and 6 on the left. The average post rehabilitation follow-up was 18 months. Peri-implant tissue reactions were observed at two sites. The implant-retained auricular prosthesis is an alternative treatment approach with good retention and patient satisfaction. Long-term follow-up is required to assess delayed sequelae.
ABSTRACT
Introduction: The midface with multiple bones and cavities is vulnerable to fractures more commonly. Midface is one of the most frequently injured areas of the body, accounting for 23%-97% of all facial fractures. The classic LeFort type of fractures are uncommon nowadays and a more common picture is more severe forms primarily due to the high-speed vehicles that are a major cause of these fractures. It, therefore, has become imperative to determine the commonly occurring patterns of fractures in this area in the present time for a better insight into diagnosis and treatment plans. The aim of this article was to determine fracture patterns in midface trauma to ease the treatment planning in such a scenario. Materials and Methods: This prospective study included 114 patients who reported to a tertiary hospital during a 4-year period and were diagnosed with suspected midface fractures. The etiology and pattern of fractures of midface were assessed based on history, clinical examination, and imaging data. The diagnosis of a fracture was based on the clinical history, signs and symptoms, manual examination, and correct interpretation of radiographs and computed tomography. Midface fractures were recorded as LeFort I, II, III, dentoalveolar, palatal, zygomatic complex fracture, nasal bones, naso-orbital-ethmoidal complex, and orbital and zygomatic arch fractures. Etiological factors were classified as road traffic accidents (RTAs), fall, assault, and sports injuries. Results: During the 4-year period, a total of 114 patients were included. Patients' ages ranged from 17 to 68 years, with 102 males and 12 females. The most common fracture in this study was found to be zygomatic complex fractures (52%), and RTA was identified as the main cause of fracture in this study (79.2%). Conclusion: The midface fractures are more common in males due to the propensity of males to use two-wheelers more than females. The prominence of the zygoma makes it more vulnerable to fractures than rest of the bones in the midface. Increased speed of vehicles and lack of discipline in following traffic rules have resulted in RTA, being the biggest etiological factor in midface injuries.
ABSTRACT
Background and Objectives: Trauma to the maxillofacial region is usually associated with varying degrees of disruption of the soft and hard tissues in the region and injuries to the neighbouring structures such as eyes, brain, nasal apparatus and paranasal sinuses. Injuries to the middle third of the face commonly destroys the integrity of the orbital skeleton, and are frequently complicated by injury to the eye, ranging between 2.7 and 67% as reported in the literature. These injuries may result in loss of vision or compromised ocular function. When these injuries are severe, they may be detected with ease by any medical or maxillofacial surgeon but many injuries appear minimal and may be missed by the non-ophthalmologist. Methods: A total of thirty patients were selected who were diagnosed with a zygomatic complex fracture, irrespective of sex predilection and in the age group of 18-70 years. All patients underwent a thorough ophthalmic examination by an Oral and Maxillofacial Surgeon and an Ophthalmologist preoperatively and on postoperative day 2, and 7 and all findings were documented separately by the surgeon and the ophthalmologist and the findings were later compared. Results: The statistical analysis was performed using SPSS VERSION 21.0, Shapiro-Wilk test which was used to assess the normality. Descriptive analysis was done for age and gender distribution of study subjects, which are expressed as number and frequency. Cochran's q test was used to determine if there are differences in various study factors among OMFS and ophthalmologists at three time intervals which are expressed as number and frequency. Kappa agreement was used to assess the measurement of agreement between OMFS and ophthalmologists for each factor at each time interval and these are expressed as number and frequency, and p ≤ 0.05 is considered as statistically significant. Upon examination by an OMFS periorbital oedema (p = 0.000), periorbital ecchymosis (p = 0.002), chemosis (p = 0.02) and exophthalmos (p = 0.03) were considered clinically significant. Upon examination by an ophthalmologist subconjunctival haemorrhage (p = 0.05), periorbital oedema (p = 0.05), periorbital ecchymosis (p = 0.00), ptosis (p = 0.006), enopthalmos (p = 0.05) and diplopia (p = 0.05) were considered to be clinically significant. Upon correlation of the findings of the surgeon and the ophthalmologist it was seen that certain parameters like corneal injury, Phthisis bulbing, examination of posterior segment can be better done by the ophthalmologist. Interpretation and Conclusion: In conclusion, it was determined that there is a significant correlation between ophthalmic injuries caused by zygomatic complex fractures. There are a wide array of injuries affecting the eye due to trauma to the middle third of the face, and the superficial injury can be well evaluated and documented by a surgeon; however due to the extensive nature of the injuries in trauma and the importance of the eye, an ophthalmic examination cannot be ruled out. The need for evaluation of such injures deem it pertinent for observation by an ophthalmologist.
ABSTRACT
Infiltrating lipomatosis is a rare benign condition causing diffuse fatty infiltration into the surrounding soft tissue and in rare cases causes hyperplasia of the adjacent bone. We report a case with clinical and radiological evidence of a 34-year-old female patient who reported a swelling in the left middle third of the face with exophytic temporomandibular joint (TMJ) ankylosis of the left side resulting in restricted mouth opening and facial asymmetry since 21 years. The number of cases reported in the literature is rare. Surgery is the treatment of choice.
ABSTRACT
AIM: The objective of this study was to correlate the preoperative radiological findings and intraoperative surgical findings during removal of impacted mandibular 3rd molar with respect to the inferior alveolar canal. MATERIALS AND METHOD: The prospective study design included 100 patients between the age group of 20 years and 50 years who visited the Department of Oral and Maxillofacial Surgery at Vydehi Institute of Dental Sciences and Research Centre, Whitefield, Bengaluru. A preoperative panoramic radiograph was taken and the parameters were assessed and a normal surgical protocol was followed to extract the impacted mandibular 3rd molar with intra-operative assessment as well. RESULTS: Out of the 100 patients with definitive radiological signs showing close relation of the third molar to the mandibular canal who underwent surgical removal, only 12 patients presented with definitive clinical findings of the association. CONCLUSION: A true close relationship between the third molars and mandibular canal increases the risk of inferior alveolar nerve injury, and accurate evaluation of the relationship is essential to avoid the risk of surgery. The accuracy of the plain radiographs to diagnose an intimate relationship between the neurovascular bundle and the third molar root has its limitations, since only 12 of the 100 patients with positive radiological signs showed clinical evidence of involvement. Surgeons should be aware of the limitations of the radiographic markers of panoramic radiography and should consider more detailed imaging in more specific cases in which one or more radiographic marker is present.
ABSTRACT
Melanotic neuroectodermal tumor of infancy (MNTI) is a rare, fast-growing, pigmented neoplasm of neural crest origin. Despite of its rapid and locally infiltrative growth, it is still considered benign with high recurrence rate and malignant potential, so early diagnosis is extremely important to limit its local expansion. Recurrences can be expected primarily because of incomplete excision, tumor dissemination, or due to its multicentric nature. We report a case of MNTI originating in the maxilla of a 7-month-old male infant, which was managed with complete surgical excision of the tumor, with no signs of recurrence after a 1-year follow-up period. In addition, a complete literature review has been reported, in an attempt to understand the origin, histopathologic and immunohistochemistry features with surgical modalities and advantages of radiotherapy and chemotherapy in cases where complete surgical extirpation is questionable.
ABSTRACT
INTRODUCTION: Patients with ischemic heart disease are placed on antiplatelet therapy (APT). This study allows a definite protocol to be set which will allow us the make the right judgment when it comes to extractions in patients on APT. MATERIALS AND METHODS: For this study, 100 patients were taken up for dental extraction after obtaining a thorough case history. Bleeding time was assessed preoperatively for all the patients and patients with normal bleeding time were taken up for surgery under local anesthesia. Local haemostatic measures were employed after the extraction. Patients were monitored for first 30 minutes at the clinic and a telephonic review of all the patients was done at 24 h-48 h interval after the procedure. If there was an active ooze from the surgical site at any point, haemostatic measures with local haemostatic agents were carried out. RESULTS: In patients with mono antiplatelet therapy, bleeding was noted in 16 patients after the 1 h time interval and was absent after 24h-48 h time intervals. The q = 32 and the P < 0.001, making it statistically significant. Regarding patients on dual APT, bleeding was noted in ten patients after 1 h, and in one patient after 24 h with no patients presenting with bleeding at the 48 h time interval. The q = 16.545 and P < 0.001, making it statistically significant. DISCUSSION: The benefits of continuing APT for patients who require dental extraction outweighs the risks of postoperative bleeding. CONCLUSION: Antiplatelets are used for the prevention of myocardial infarction, ischemic stroke, and vascular death among patients who are at high risk of these events. Antiplatelets have minimal impact on the amount and duration of bleeding following routine dental extractions.
ABSTRACT
AIM: Temporomandibular joint (TMJ) ankylosis is an extremely disabling affliction that causes problems in mastication, digestion, speech, appearance and hygiene. Surgery of TMJ ankylosis needs careful evaluation and planning to yield predictable results. Temporomandibular joint ankylosis is very common among young children. The aim of treatment is not only to treat the movement of the joint but also to prevent relapse. MATERIALS AND METHOD: In this series, 18 cases of temporomandibular joint ankylosis were treated at our institute from January 2012 to January 2017 with osteoarthrectomy and interpositional arthroplasty. Patients were in the age range of 5-57 years, with 11 males and 7 females and including 8 unilateral and 10 bilateral cases. Duration of ankylosis ranged from less than 2 years to more than 6 years. Seven of the patients were secondarily taken up for correction of their deformities with either orthognathic surgery or distraction osteogenesis. RESULTS: Good mouth opening was achieved in all the patients with a mean follow-up period of 12 months. The early post-operative mouth opening ranged from 24 to 37 mm. The late post-operative mouth opening ranged from 20 to 33 mm. There was a stress on aggressive physiotherapy for a minimum of 6 months in all our patients. CONCLUSION: Interpositional arthroplasty using vascularized temporalis fascia flap is a very reliable method to prevent recurrence of ankylosis, and it also avoids the disadvantages of alloplastic materials as well as nonvascularized autogenous tissues.
ABSTRACT
INTRODUCTION: Odontogenic keratocysts (OKCs) are benign intraosseous odontogenic lesions that have a locally aggressive behavior and exhibit a high recurrence rate after the treatment. The most appropriate surgical approaches for the successful treatment of OKCs remain controversial. AIM: The aim of this study was to evaluate the conservative management of OKCs by enucleation along with peripheral ostectomy and chemical cauterization in terms of recurrence rates after the surgical procedure. MATERIALS AND METHODS: A retrospective study on 36 cases of OKCs treated at the Oral and Maxillofacial Surgery Department of a tertiary hospital from 2010 to 2017 was done. The demographic, clinical, radiographic, and histologic data were collected for each patient. All cases were surgically treated by enucleation followed by peripheral ostectomy and chemical cauterization using Carnoy's solution. The teeth that were involved in the lesion were extracted. The diagnosis was confirmed with excisional biopsy and histopathology reports. RESULTS: Most of the OKCs were found in the mandible, except three which were present in the maxilla. A significantly higher incidence was seen in males in the age group of 21-30 years. Most of the cases (30 out of 36 cases) were accessed intraorally. Patients were followed up for up to 5 years. Recurrence of the operated OKCs was observed in five cases which were managed by enucleation with peripheral ostectomy and chemical cauterization again with good results. CONCLUSION: The results suggest that proper enucleation followed by peripheral ostectomy and chemical cauterization using Carnoy's solution may be the best and optimal approach for the management of OKC.
ABSTRACT
OBJECTIVE: The objective of this study is to analyze the maxillofacial fracture pattern from road traffic accidents (RTAs) in cases treated surgically in a tertiary hospital during July 2008-June 2018. MATERIALS AND METHOD: Data available in the department of oral and maxillofacial surgery of the institution of patients with maxillofacial fractures sustained due to RTAs that were treated in the department between the period July 2008 and June 2018 were collected and analyzed. The variables analyzed for the study were etiology, gender, age, and type of fracture. All cases were treated by open reduction and rigid internal fixation. RESULTS: A total of 348 patients with maxillofacial fractures were diagnosed, of which 335 were male and 13 were female. The ages ranged from 7 to 70 years. The maximum cases were in the age group of 16-30 years with 181 fractures followed by 31-45 group with 133 fractures, 45-60 years with 21 fractures, 0-15 years with 8 fractures, and >60 years with five fractures. The maximum incidence of fractures was in the mandible with 168 cases followed by 92 in zygomatic complex, combination of fractures in 53 cases, 13 LeFort I fractures, nine frontal bone fractures, three fractures in other areas, five nasal fractures, and five LeFort II fractures. Males predominated the cases of mandibular fractures involving multiple sites and cases involving multiple bones. CONCLUSION: A maximum number of maxillofacial fractures cases were in the second and third decades of life, and the high-speed vehicles and lack of protective safety accessories such as helmets and seatbelts were responsible for the wide variety of pattern fractures of facial bones.
ABSTRACT
Removal of pathological lesions from the mandible can leave a disfiguring appearance in addition to compromising the function of speech and mastication. It therefore becomes imperative to replace the lost part with bone grafts. Autogenous bone grafts-vascularised and non-vascularised, have been in vogue for the same. The probability of using the same resected bone after removal of all pathology has been done for a long time with mixed results in terms of uptake and viability. This paper presents a case of the use of autoclaved resected bone being used for reconstructing the mandible.
ABSTRACT
Accurate staging and timely assessment is critical in head-and-neck cancer patients for formulating the appropriate treatment strategy. Therefore, optimizing pretreatment imaging for diagnosis is of great importance. Computerized tomography (CT), introduced in the early 70s, followed by magnetic resonance imaging (MRI) and positron emission tomography (PET), refinements in ultrasonography (USG), advances in nuclear medicine, and applications such as sentinel node lymphoscintigraphy have greatly added to diagnostic accuracy. Post-treatment CT or MRI is of value when a recurrent tumor is suspected. It can confirm the presence of such a lesion and determine its extent. This is important information for determining the possibility of salvage therapy.

Malignant Peripheral Nerve Sheath Tumour (MPNST) also termed as spindle cell malignancy of the peripheral nerve schwann cell or neurogenic sarcoma represents 10% of all soft tissue sarcomas. The tumour is usually found in lower extremities and only 10% to 20% of all lesions occur in head and neck region thus making it a rare entity. Central involvement, particularly in the jaw bones is quite unusual. Neurofibroma is one of the common nerve sheath tumours occurring in the soft tissues and generally appears in neurofibromatosis I (NF-I or von recklinghausen's disease). MPNST are uncommon sarcomas that almost always arise in the soft tissues. Here we report a case of intraosseous peripheral nerve sheath tumour occurring in the mandible and discuss the surgical management with adjuvant and neoadjuvant treatment plan.
