Assessment of Nerve Function After Mandible Surgery With a Modified Bilateral Sagittal Split Osteotomy Technique
Sponsored by Chang Gung Memorial Hospital
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.
Inclusion Criteria: * patients receiving mandibular bilateral sagittal split osteotomy during orthognathic surgery with normal preoperative intraalveolar nerve function * patients with cleft lip/palate or hemifacial microsomia were also included Exclusion Criteria: * craniofacial syndromic condition, abnormal psychomotor development or previous history of mandibular fracture
