Abstract

Objective: The purpose of this study was to evaluate subjective and objective outcomes in patients with temporomandibular joint (TMJ) ankylosis treated with TMJ alloplastic reconstruction (TMJR). Study Design: All patients diagnosed with TMJ ankylosis that underwent TMJR at our institution between 2010 and 2019 were retrospectively reviewed. Patients were divided into 2 cohorts: bony and fibrous ankylosis. Subjective variables assessed were facial pain and headaches, TMJ pain, jaw function, diet, and disability. Objective variables assessed were maximum interincisal opening and lateral excursions. The Mann-Whitney test was employed to analyze subjective variables and an unpaired t-test was used to analyze the objective variables. P < .05 was considered statistically significant. Results: Twenty-eight patients met the inclusion criteria (21 female, 7 male). The mean age at the time of surgery was 42 years, and the mean number of prior TMJ surgeries was 3. A total of 52 TMJRs were performed in the 28 patients, and the mean follow-up time was 46 months. All subjective variables were significantly improved, and the mean maximum interincisal opening increased from 16.9 mm to 37.25 mm. Conclusions: The results of the study demonstrate that TMJR is an effective and reliable method for the management of both fibrous and bony TMJ ankylosis.
