为观察不同时期神经移植修复面神经的效果及差别的程度，得出面神经修复的理想期限和可行期限，将家兔６６只随机分为７组，行面神经缺损后耳大神经移植修复，于术后不同时间通过电生理学、组织病理学、组织化学染色、电镜等方法观测不同时期神经移植修复面神经的效果及差别程度。结果表明，除即刻移植组外，２个月以内的延迟移植效果最好，３个月是应积极争取的期限，８个月至１年移植后仍有部分神经功能可恢复。因此，面神经损伤后修复越早效果越好，延迟移植在２个月内为理想期限，１年内为可行期限。
In order to observe the effects and differences of facial nerve repaired by nerve transplantation in different periods, the ideal period and feasible period of facial nerve repair were obtained. Sixty-six rabbits were randomly divided into seven groups. After facial nerve defect, At different times, electrophysiological, histopathological, histochemical staining and electron microscopy were used to observe the effects and differences of facial nerve repaired at different stages of nerve transplantation. The results showed that, except for the immediate transplantation group, delayed transplantation within 2 months had the best effect, and 3 months was the period that should be actively pursued. Some neurological functions were still recovered from 8 months to 1 year after transplantation. Therefore, the sooner the effect of facial nerve repair after injury is better, delayed transplantation within 2 months is the ideal period, one year is a feasible period.
