摘要
目的:观察下颌支矢状劈开截骨术后下唇感觉功能障碍发生及恢复情况。方法:对21例41侧下颌支矢状劈开截骨术患者进行24周的随访。根据术前、术后4天、4周、12周、24周随访中患者下唇部触觉、痛觉及两点辨别觉的变化,按BMRC感觉功能评定标准,判定下唇感觉功能障碍的恢复情况。使用SAS6.12统计软件包进行多个样本率间的χ2检验。结果:术后4天时,下唇感觉功能障碍的发生率为100%,感觉丧失发生率为85.4%。术后4周时,感觉障碍恢复优秀率为14.6%,术后12周为67.6%,术后24周为81.1%,32.4%的患者于随访期末达到完全恢复。两侧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>0.05)。结论:SSRO术后早期感觉功能障碍较为普遍,但大多数(81.1%)患者在术后12～24周可达到“优”等级恢复。
PURPOSE： This study was designed to evaluate the incidence and recovery of postoperative sensory disturbance after sagittal split ramus osteotomy（SSRO）. METHODS： We studied 21 consecutive patients that underwent a total of 41 SSROs or combined with Le Fort I osteotomy from September 2004 to September 2005. The follow-up period was 24 weeks. The condition of sensory disturbance was measured using touch test, prick test and two-point discrimination test. The standard of the BMRC grading system was used to evaluate sensory function. SAS6.12 software package was used for chi-square test. RESULTS： The results demonstrated that incidence of immediately postoperative sensory disturbance was 100%. The incidence of sensory deprivation was 85.4%. Sensory disturbance could recover gradually postoperatively. 32.4% of the patients could achieve complete recovery. No significant difference in sensory function was found between the recovery rate of left and right sides. CONCLUSIONS： It was concluded that immediate sensory disturbance after SSRO is very common, sensory deprivations exist in most patients. Nearly 1/3 patients can achieve complete recovery. The condition of recovery between left and right is of conformity.
