Abstract
Correction of cranio-maxillofacial deformity by means of orthognathic surgery includes procedures that may cause impaired sensory nerve function in the facial skin distribution. The most common site for such disturbance is the lower lip and chin area following a sagittal split ramus osteotomy of the mandible. Most often, however, such impaired sensitivity is tolerated well by the patient, but careful preoperative information about the risk of obtaining a neurosensory impairment is of primary importance in patient management. It is generally accepted that inferior alveolar nerve injury is the most common complication of mandibular orthognathic surgery, with immediate neurosensory dysfunction occurring in nearly 100 % of patients and long-term paresthesia occurring to a variable degree.
