A Modified Technique of Mandibular Ramus Sagittal Split Osteotomy for Prevention of Inferior Alveolar Nerve Injury: A Prospective Cohort Study and Outcome Assessment
In Brief
A clinical study evaluating bilateral sagittal split osteotomy for Neurosensory Function of Inferior Alveolar Nerve. Completed, enrolled 57 participants.
Detailed Summary
Several technical modifications based on the anatomical position of the neurovascular bundle and its bony mandibular canal have been developed, aiming to prevent injury to the intraalveolar nerve We hypothesized that the incidence of neurosensory disturbance (NSD) should be reduced using our bilateral sagittal split osteotomy (BSSO) technique, because direct intra-alveolar nerve injury can be avoided. The aim of this study was to introduce our modified BSSO technique and evaluate the subsequent incidence of postoperative neurosensory disturbance of the IAN.

Interventions
surgical technique to split the mandibular ramus through three osteotomy lines on the medial-cranial, buccal-caudal and anterior surface to facilitate a split of the posterior border of the mandible without injury of the inferior alveolar nerve
