Abstract: Inferior alveolar nerve injury (IAN) is the most common complication after mandibular orthognathic surgery. And it is also the issue that patients and surgeons are all concerned about. Morbidity of IAN injury is reported differently. Influence factors of its occurrence include anatomy and operation ones. As the most famous orthognathic operation, the operative skills of mandibular sagittal split ramus osteotomy have a close relation with IAN injury. The main symptom of IAN injury is anaesthesia of lower lip, chin, and gingiva in affected side. A small number of patients show continuous pain, pressing pain and suffering from occlusal pain or discomfort. This paper reviews pathogenic characteristics, influencing factors, clinical manifestations and therapies of IAN injury after orthognathic surgery and makes a brief summary.
