The recovery of the mechanosensitive afferent fibres in the lingual branch of the trigeminal nerve has been studied using electrophysiological techniques in cats, after two methods of nerve repair. After nerve section the lingual nerve was repaired by either epineurial sutures or by entubulation. 12 weeks after either method of repair the properties of the regenerated fibres were significantly different from normal, but following repair with epineurial suture they were closer to normal than after repair by entubulation. After entubulation the fibres had a greater reduction in conduction velocity, a greater increase in force threshold, and the adaptation times were faster. The results suggest that epineurial suture should be preferred clinically.
在猫身上，运用电生理技术，通过两种神经修复方法，研究了三叉神经舌支中机械敏感传入纤维的恢复情况。神经切断后，舌神经通过神经外膜缝合或套入法进行修复。两种修复方法术后12周，再生纤维的特性均与正常情况有显著差异，但神经外膜缝合修复后的纤维特性比套入法修复后的更接近正常。套入法修复后，纤维的传导速度降低幅度更大，力阈值增加幅度更大，适应时间更快。结果表明，临床上应优先选择神经外膜缝合。
