目的本回顾性研究探讨了下颌升支矢状劈开截骨术（SSRO）后神经感觉障碍（NSD）程度与下颌运动距离的关系，并评估了感觉恢复情况。方法对38例患者在SSRO后1周、1个月和2个月进行了下唇感觉减退的评估，根据下颌运动距离分为：S组（0-7 mm;n= 17，4名男性和13名女性）和L组（7-14 mm;n= 21，7名男性，14名女性）。采用视觉模拟评分法（VAS）、视觉阈值（SW）、静态2点辨别（S-2 PD）、电流感知阈值（CPT）等方法对患者的症状进行评估。术后1周和1个月Aβ纤维CPT试验结果在两组间差异有统计学意义（P< 0.05）。有没有组之间的VAS，SW，s-2 PD，Aδ纤维，和CPT.ConclusionsPost-SSRO的C纤维在整个期间的差异无统计学意义，NSD的发生率在触觉方面的L组术后早期可能更大。这可能有助于外科医生在术前向患者解释术后感觉减退。
PurposeThis retrospective study investigated the relationship between the degree of neurosensory disturbance (NSD) and mandibular movement distance after sagittal split ramus osteotomy (SSRO) and assessed sensory recovery.MethodsLower lip hypoesthesia was evaluated at 1 week, 1 month, and 2 months after SSRO in 38 patients categorized according to the distance of mandibular movement: S group (0–7 mm;n= 17, 4 males and 13 females) and L group (7–14 mm;n= 21, 7 males, 14 females). Symptoms were evaluated by visual analog scale (VAS), tactile-threshold (SW) test, static 2-point discrimination (s-2PD) test, and current perception threshold (CPT) test.ResultsThe two groups did not differ significantly in gender and age. The Aβ fiber results of the CPT test differed significantly between the groups at 1 week and 1 month postsurgery (P< 0.05). There were no significant differences between the groups throughout the period in terms of VAS, SW, s-2PD, Aδ fiber, and C fiber of CPT.ConclusionsPost-SSRO, the incidence of NSD in terms of tactile sensation may be greater in the L group early postoperatively. This may assist surgeons in explaining postoperative hypoesthesia to patients preoperatively.
