摘　　要：目的　应用主观和客观测试神经感觉功能恢复的方法 ,检测双侧下颌升支矢状截骨(bilateralsagittalsplitosteotomy ,BSSO)后下齿槽神经 (inferioralveolarnerve ,IAN)暂时和永久性神经损伤的发生率和感觉恢复的时间。方法　选择 14例双侧下颌升支矢状截骨的IAN ,在术前和术后 7d ,1,3,6和 12个月采用针剌检测、两点分辨、直流感应电测法决定IAN的损伤和感觉的恢复。结果　IAN暂时性损伤率为 78% (2 2 2 8) ,单侧IAN永久性感觉丧失占 7% (2 2 8)。结论　IAN经损伤术后需 6～ 12个月感觉完全恢复 ,术中IAN断离可致永久性神经损伤。Objective\ The purpose of this study was to determine the incidence of temporary and permanent sensory disturbance of the inferior alveolar nerve (IAN) after bilateral sagittal split osteotomy (BSSO) of the mandible. Methods\ 14 patients were selected for this study. Before BSSO and at 1 week, 1, 3, 6 and 12 months after BSSO, the sensibility of bilateral inferior alveolar nerves were examined using sharp\|blunt testing, 2\|point discrimination, electronic pain response test (ZGK\|1 electrometer). Results\ With conventional sharp\|blunt and 2\|point discrimination test, electronic pain response test, the incidence of temporary impairment of IAN after BSSO was 78% (22/28). Obvious sensory recovery of IAN was found 6 to 12 months postoperatively. Permanent sensory disturbance of unilateral inferior alveolar nerve occurred in 2 patients. Conclusions\ Sensory recovery of the inferior alveolar nerve after bilateral sagittal split osteotomy of the mandible would take 6 to 12 months. Serious injury of the IAN would cause permanent neurosensory deficits.\;
