Facial movement following hypoglossal-facial nerve anastomosis was investigated in 29 acoustic neuroma patients. The amount of facial movement was assessed using both the grading system of House and Brackmann and the revised grading scale of Yanagihara. The data were analyzed to determine the influence of the time elapsed between tumor resection and anastomosis upon recovery of facial movement. A slightly larger number of patients with delayed anastomosis (7-23 months) showed minimally poorer results than those with early anastomosis (within 3 months). However, these differences were not statistically significant. Moreover, there was no apparent relationship between the duration of facial nerve paralysis and the recovery of facial movement within either of these two groups. These results showed that hypoglossal-facial nerve anastomosis can be delayed up to 2 years following tumor resection with only minimal effect on the recovery of facial movement.
对29例听神经瘤患者进行了舌下神经-面神经吻合术后面部运动情况的研究。采用House和Brackmann分级系统以及柳原修订的分级量表对面部运动程度进行评估。分析数据以确定肿瘤切除与吻合之间的时间间隔对面部运动恢复的影响。与早期吻合（3个月内）的患者相比，延迟吻合（7 - 23个月）的患者数量略多，结果略差。然而，这些差异无统计学意义。此外，在这两组中，面神经麻痹的持续时间与面部运动恢复之间均无明显关系。这些结果表明，肿瘤切除后舌下神经-面神经吻合可延迟至2年，对面部运动恢复的影响极小。
