Coronoidectomy, masticatory myotomy and buccal fat pad graft in management of advanced oral submucous fibrosis.

The purpose of this study is to evaluate coronoidectomy, masticatory myotomy and buccal fat pad graft in advanced (Stage III-IV) oral sub mucous fibrosis (OSF). 10 patients with clinically and histologically confirmed advanced OSF underwent surgery entailing bilateral coronoidectomy, masticatory muscle myotomy and closure with a pedicled buccal fat pad graft followed by vigorous mouth opening exercises. The result was evaluated using the interincisal distance at maximum mouth opening as the objective outcome measure over a follow up period of 12 months. Results showed a mean interincisal opening of 14.7 mm preoperatively and 32.5 mm at 12 months postoperatively. Relapse was encountered in one patient who did not cooperate with the postoperative exercise regime. Results suggest this regime is effective.
