化学去细胞同种异体神经修复家兔面神经缺损

目的探索修复面神经缺损的一种新的有效替代材料。方法24只兔子随机分成实验组(化学萃取同种异体腓神经移植组,12只)和对照组(自体新鲜面神经移植组,12只)。每只兔子右侧面神经下颊支被切断以造成面神经缺损1 cm的模型,同时两组兔子分别以去细胞同种异体神经和自体面神经桥接修复。术后3个月行肌电图、电镜、图像分析仪以及靶肌肉运动终板染色检查。结果术后3个月两组在神经传导速度、有髓神经纤维计数、靶肌肉运动终板计数上的差异没有统计学意义,电镜检查结果相似。结论化学去细胞的同种异体神经在面神经缺损修复上是自体神经的一种有效替代物。

Repair of facial nerve defect in rabbit with chemical acellular allogenic nerve

Objective To explore an new effective alternative material for the repair of facial nerve defects.Methods Twenty-four rabbits were randomly divided into trial group(repair facial nerve defect with chemical acellular allogenic peroneal nerve graft,12 cases) and control group(repair facial nerve defect with fresh inverted autologous facial nerve,12 cases).The jowl segment of right facial nerve of every rabbit was cut off to make the model of jowl segment defect of right facial nerve in rabbit with 1 cm in len...
