Protocol for Single-Stage Bilateral Temporomandibular Joint Replacement Using Intraoperative Navigation in Patients With Ankylosis.

Treatment of patients with bilateral temporomandibular joint (TMJ) ankylosis in a single-stage procedure can be challenging. The implementation of intraoperative navigation has proved beneficial by enabling faster and safer excision by providing real-time identification of vital structures. Navigation also can be used to verify site preparation for custom joint prostheses. This article seeks to establish a protocol, based on the use of intermaxillary fixation screws, to produce accurate and repeatable outcomes for the correction of bilateral TMJ ankylosis with total joint replacement in a single-stage procedure.
