Introduction: Comprehensive management of TMJ ankylosis including restoration of form, function and aesthetics is a challenging aspect for Oral & Maxillofacial Surgeon. Various treatment modalities have been reported in the literature with their merits, demerits and diverse success rate. Materials and Method: We report our experience in reconstruction of Ramal Condylar Unit (RCU) in temporomandibular joint ankylosis patients in a retrospective review. A total of 06 cases of TMJ ankylosis were included in the review. The cases were managed in our tertiary care centre from June 2019 to June 2020. Demographic distribution of the patients, preoperative findings, surgical modalities used for RCU reconstruction and postoperative outcome were recorded and compared. Results: Average mouth opening increased from 8.5 mm pre-operatively to 29.5 mm 3 months postoperatively. 02 cases of Sawhney’s type I and II ankylosis were managed by interpositional gap arthroplasty using temporalis myofascial flap. 01 case of Sawhney’s type I ankylosis was managed by gap arthroplasty interposed with dermis-fat graft. 02 cases of Sawhney’s type III ankylosis were managed by osteoarthrectomy and reconstruction of RCU by costochondral graft. In 01 case with Sawhney’s type III ankylosis, functional joint was reconstructed using distraction osteogenesis. We encountered 01 case of recurrence in a case managed by costochondral grafting. Conclusion: Amongst the various modalities suggested in the literature, the RCU reconstruction with distraction osteogenesis and costochondral grafting provide best result functionally and aesthetically. The diagnosis, timely management and post-operative follow up are the key to success in TMJ ankylosis.
