PURPOSE
The purpose of this study was to investigate the outcome of different injuries to the facial nerve.
MATERIALS AND METHODS
Six patterns of injuries (exposure, compression, crushing, stretching, division and post-division anastomosis) were produced in the buccal branches of the facial nerve in 60 rabbits. Electroneuronography (ENoG) and histology at definite time were used to evaluate the results.
RESULTS AND CONCLUSIONS
Exposure and compression injuries produced a neuropraxic injury and rapid recovery. Crushing and stretching injuries resulted in axonotmesis and whilst complete recovery can take place it may be very slow. Division and post-division anastomosis fall into neurotmesis injury and do not completely recover within six months; the former recovers slower and later than the latter.
目的
本研究旨在探讨面神经不同损伤的结果。
材料与方法
对60只家兔的面神经颊支造成六种损伤模式（暴露、压迫、挤压、拉伸、切断及切断后吻合）。在特定时间进行神经电图（ENoG）检查和组织学检查以评估结果。
结果与结论
暴露和压迫损伤导致神经失用性损伤且恢复迅速。挤压和拉伸损伤导致轴突断裂，虽然可完全恢复，但可能非常缓慢。切断及切断后吻合属于神经断裂伤，六个月内不能完全恢复；前者恢复比后者更慢且更晚。
