Abstract

Abstract: Objective: To explore the treatment of TMJ ankylosis with secondary dentocacial deformities. Methods: This was a retrospective analyze of 18 pediatric patients with TMJ ankylosis and secondary dentofacial deformities. Clinical outcomes were evaluated in terms of oral function, medical photography, and radiography. Patients were followed up for 12-40months. Results: The patients underwent different types of arthroplasty with condylar reconstruction by costochondral bone, autogenous coronoid process or distraction osteogenesis. The dentofaical deformities were treated simultaneously. No infections had occurred during or after hospitalization. No patients with re-ankylosis or permanent facial nerve damage were found during the follow-up period. All patients achieved significant improvements in MIO (2.83mm preoperative to 30.5 mm 12 months postoperative, P<0.05) and in oral function including chewing, swallowing, pronunciation, and respiration with long-term follow-up. The dentofacial deformities in most patients were improved to varying degrees. Conclusion: Our results provided more useful information for the management of the pediatric patients with TMJ ankylosis and secondary dentofacial deformities. Early treatment and close follow-up play an important role in the management of these patients.
