Unusually rare occurrence and recurrence of temporomandibular joint ankylosis and oral submucous fibrosis simultaneously in a patient: A surgeon's dilemma

We here present a rare case of simultaneous occurrence and recurrence of TMJ ankylosis and submucous fibrosis in the same patient. Patient presented with limited mouth opening at both occasions. However, the diagnosis of submucous fibrosis was overlooked at the first presentation. The patient reported with recurrence of both the conditions after a period of 15 years. We presume that noncompliance of jaw exercises aggravated both the conditions as one led to the other. Since fibrosis sets in earlier than bony fusion, we theorized that the patient had acquired OSMF before TMJ ankyloses recurrence. The case was managed with release of fibrous bands intraorally followed by release of TMJ ankylosis and interposition with dermis fat graft. Physiotherapy is extremely essential when either pathology is treated in patients, especially when both are present in a single patient.
