Abstract
This is a case report of a 19 year old adult female with facial asymmetry secondary to right Temporomandibular Joint (TMJ) ankylosis with a history of previous surgery at the age of 10 years with gap arthroplasty for tmj ankylosis which was unsuccessful and lead to relapse .Because of decreased mouth opening and facial disfigurement patient was not able to have a quality life. She reported to our department where she got operated simultaneously for tmj ankylosis with interpositional arthroplasty using temporalis myofascial flap and novel osteotomy technique for correction of chin asymmetry. After surgery there is a significant improvement in patient both functionally and aesthetically.
Highlights
Temporomandibular Joint (TMJ) ankylosis is one of the known cause for facial asymmetry.It might be either a fibrous union or bony union of TMJ joint with the glenoid fossa resulting in reduction of mouth opening, difficulty in speech and mastication and leading to facial asymmetry [1]
Eventhough TMJ ankylosis when addressed at an early age which corrects the mouth opening but the facial asymmetry which is a result of this requires a second surgery for its correction
We are reporting a case of 19 year old female with right tmj ankylosis and facial asymmetry who got treated simultaneously with interpositional arthroplasty using a temporalis myofascial flap for ankylosis release and novel osteotomy technique for correction of chin asymmetry
Summary
TMJ ankylosis is one of the known cause for facial asymmetry.It might be either a fibrous union or bony union of TMJ joint with the glenoid fossa resulting in reduction of mouth opening , difficulty in speech and mastication and leading to facial asymmetry [1]. We are reporting a case of 19 year old female with right tmj ankylosis and facial asymmetry who got treated simultaneously with interpositional arthroplasty using a temporalis myofascial flap for ankylosis release and novel osteotomy technique for correction of chin asymmetry. In this novel osteotomy technique the chin discrepancy was measured preoperatively using the cephalograms and the asymmetry is corrected
