A Novel Technique for Resection and Reconstruction of the Temporomandibular Joint by Sliding Vertical Ramus Osteotomy using Only Submandibular Approach.

Abstract

In this paper, an innovative technique for resection and reconstruction of the temporomandibular joint by sliding vertical ramus osteotomy using only a submandibular approach is presented. Before pulling the posterior mandibular border slightly downward to expose parts of the condyle, the vertical ramus osteotomy was performed. With the help of 3D simulation and surgical templates, the condylectomy was carried out using the ultrasonic osteotome through the submandibular approach. Our technique achieved the desired results while preventing complications of facial nerve paralysis, the occurrence of Frey syndrome, and the preauricular scar. Therefore, we suggest that this surgical method represents an alternative treatment option for temporomandibular joint lesions.
