Semmes—Weinstein单丝检测下颌骨矢状劈开截骨术后下牙槽神经功能的初步研究
[摘要]目的：客观评价下颌失状劈开截骨术后下齿槽神经感觉障碍发生及自然恢复的发生率。方法：选择30例双侧下颌升支矢状截骨的患者在术前和术后1周、4周、2个月和6个月进行下齿槽神经感觉障碍的临床评价。30例患者均采用Semmes-Weinstein单丝测试法。结果：术后7天感觉障碍发生率为100%。在所有检测区域，术后6个月的测量结果与术前最接近。6个月时20例患者感觉恢复术前水平。左右侧及性别间感觉障碍恢复优秀率的差异在各个随访时期均无统计学意义（P>O.05）。结论：BSSO术后早期感觉功能障碍较为普遍，然而在术后6个月，大多数患者的神经功能可达到自然恢复。

Abstract： Objective The aim of this prospective study was to objectively evaluate the inferior alveolar nerve （IAN） paresthesia in patients who underwent bilateral sagittal split osteotomy （BSSO） and its spontaneous recovery and to define the incidence of sensibility loss. Methods Clinical evaluation of the IAN sensory disturbance was undertaken preoperatively and at the first week， fourth week，2 months，and 6 months postoperatively in 30 patients who underwent BSSO.The 30 patients were examined at all periods regarding the IAN functionality by Semmes-Weinstein testing. Results All patients showed sensibility loss at the 7-day evaluation time. The comparison between sides and gender did not show any significant difference（P>0.05）.The examined data collected at 6 months were statistically similar to the data colle...
