Condylar Hyperplasia: Case Report and Literature Review.

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.

TMJ Ankylosis Management: Our Experience.

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.
