Treatment of Mandibular Bone Cyst by Navigation and Endoscopy

In this study, with the assistance of endoscopic technology and intraoperative navigation technology, the removal and curettage of large odontogenic jaw cyst occurred in the mandible were performed to reduce the rate of postoperative nerve injury. In this study, the investigators compared the efficacy of traditional extraction and curettage with endoscopic navigation assistance in the treatment of giant mandibular bone cysts. In this study, the rate of inferior alveolar nerve injury 1 month after surgery was taken as the main outcome index, and the recurrence rate 1 year after surgery was taken as the secondary outcome index, to explore whether endoscopic combined with intraoperative navigation-assisted treatment of giant mandibular bone cyst could achieve lower postoperative nerve injury rate and postoperative recurrence rate.
