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-Wei nst ei n...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-Wei nst ei n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。展开更多

The purpose of this study was to examine short- and long-term regeneration results after digital nerve reconstruction with muscle-in-vein conduits. Static and moving two-point discriminations and Semmes-Weinstein Monofilaments were used to evaluate sensory recovery 6–12 months and 14–35 months after repair of digital nerves with muscle-in-vein in 7 cases. Both follow-ups were performed after clinical signs of progressing regeneration disappeared. In 4 of 7 cases, a further recovery of both two-point discriminations and in another case of only the static two-point discrimination of 1–3 mm could be found between the short-term and long-term follow-up examination. Moreover, a late recovery of both two-point discriminations was demonstrated in another case. Four of 7 cases showed a sensory improvement by one Semmes-Weinstein Monofilaments. This pilot study suggests that sensory recovery still takes place even when clinical signs of progressing regeneration disappear.展开更多
