Introduction
Many surgical techniques have been described for the treatment of TMJ ankylosis, but no strategy has been uniformly agreed upon underscoring the difficulty of the problem. Despite new guidelines and updated methods, treating patients with TMJ Ankylosis remains a challenge as the incidence of recurrence after treatment is soaring. This study exemplifies our experience in using an unsullied method to treat TMJ Ankylosis to restore the structure of TMJ in conjunction with convalescing secondary maxillofacial deformity.
Materials and Methods
A total of 56 cases of unilateral bony TMJ ankylosis were included in the study, and postoperative results of T.M.J disc as a soft tissue interposition graft was evaluated. The operative protocol comprised of (1) resection of ankylotic mass, (2) intraoral ipsilateral coronoidectomy or contralateral coronoidectomy when needed, (4) interpositioning disc as soft tissue graft, (5) interposing and fixing sternoclavicular or costocondral graft with lag screws and (6) early mobilization, aggressive physiotherapy.
Results
The study assessed patients with regular follow‐up checks for a period of 3 years. The average preoperative mouth opening was found to be 5.46 mm (range 2–10 mm). Mean post-operative mouth opening was 33.05 mm (range 24–43 mm), while 3 years post operative mouth opening (mean) was 39.75 mm. No cases of reankylosis were reported during this period suggesting it as a viable and satisfactory approach.
Conclusion
The use of TMJ disc as a soft tissue interpositional graft material is an effectual method for functional rehabilitation of ankylosis cases and serves as an effective means of preventing recurrence.
