Patient-Specific surgical management of a triad of TMJ ankylosis, micrognathia, and obstructive sleep apnea: A case report.

Abstract

A triad of TMJ Ankylosis, Micrognathia, and Obstructive sleep apnea syndrome (OSAS), is common in prolonged cases of TMJ ankylosis or TMJ Re-Ankylosis. The goals of managing a case of TMJ ankylosis include creating a functional joint, improving the aesthetic appearance, treating OSAS, and preventing re-ankylosis. This case study documents the treatment of a 26-year-old male with bilateral TMJ re-ankylosis, which was more pronounced on the right side while considering the social and financial constraints of the patient. The case was managed by interpositional arthroplasty and advancement sliding genioplasty to correct facial asymmetry as well as to increase the posterior airway space, which was followed by an aggressive physiotherapy. Significant improvement in the patient's mouth opening and facial profile was observed after the treatment. The post-operative outcome is being assessed at regular follow-ups. This integrated approach demonstrates efficacy in addressing TMJ ankylosis, emphasizing the critical role of postoperative rehabilitation in achieving favorable results.
