摘　　要：目的探讨螺旋水刀在腮腺切除术中的应用,观察其对实验动物面神经的损伤情况。方法选择12只成年雄性杂种狗,实验组(左侧)采用德国ERBE螺旋水刀进行面神经解剖,对照组(右侧)采用传统方法解剖面神经,两侧均进行保留面神经的腮腺全切术,术中记录手术时间,术后观察双侧面瘫情况并进行对比分析。结果两组动物手术时间无明显差异。实验组面瘫发生例数与对照组相比明显减少,两组对比,差异有统计学意义(P<0.05)。结论水刀分离技术用于狗面神经解剖可以明显减轻面神经损伤,值得进一步在临床推广。Objective To investigate the application of the water-jet dissection method in parotid surgery by way of animal experiments, especially the degree of facial nerve injury. Methods Total bilateral parotidectomies with retention of the facial nerve were performed on 12 dogs. Facial nerve dissection of the experimental group （the left side） was performed by ERBE HELIX HYDRO-JET device. On the control group（the right side）, traditional operation method was applied. The duration of operation was recorded. Facial paralysis information was observed and compared after operations. Results There is no significant difference in duration of operation between the two groups. The facial nerve paralysis occurrence in the experimental group was significantly lower than that in the control group （P 〈 0.05）. Conclusion Water-jet in the use of facial nerve dissection on dog can obviously reduce facial nerve paralysis rate. It＇s of worthy to be applied in clinical practice.
