The standard surgical treatment for mandibular prognathism is sagittal split ramus osteotomy (SSRO) if the proximal and distal segments of the ramus require fixing with screws or metal plates. In this procedure, however, it is frequently difficult to avoid neurosensory disturbance (NSD) of the inferior alveolar nerve (IAN) when the posterior margin of the ramus curves inward or when the ramus i...

Aim: To evaluate neurosensory disturbance after using separators Vs chisels in bilateral sagittal split osteotomy. Methods: A total of (18 patients) 36 sides indicated for BSSO randomly assigned to 2 equal parallel groups; 9 patients sides) treated (control group) and were by (intervention group). The was assessed each side. Result: After one year follow up separator group showed dysfunction 11...
