Abstract

Abstract: PURPOSE: To investigate the application and value of intraoperative CT in the treatment of temporomandibular joint (TMJ) ankylosis. METHODS: Four patients (5 sides) who underwent surgery of TMJ ankylosis using intraoperative CT from July 2016 to December 2018 were retrospectively studied. Demographics, surgical factors, and clinical outcomes were analysed. RESULTS: All 4 patients were successfully operated with the aid of intraoperative CT imaging and CT-directed revisions were made in three of them during surgery. The average time spent in scanning was (10.2±3.3) minutes. No surgical complications were noted and a good satisfaction rate (with an average mouth opening of 38.8 mm) was obtained. CONCLUSIONS: Intraoperative CT scanning is a useful tool in evaluation of the surgical results of TMJ ankylosis, and a real-time revision could be made. It increased precision and safety of the surgery of TMJ ankylosis.
