目的：提高人工耳蜗植入成功率，减少并发症，优化手术过程。方法将不锈钢凹面勺打磨成凹面形头皮拉钩，应用于120例人工耳蜗植入术中。结果120例患者应用新型凹面勺头皮拉钩，证明其能充分暴露手术视野，避免拉钩与钻头摩擦，导致钻头耗损及产生金属屑，减少术者体力消耗及头皮组织挫伤。结论利用不锈钢凹面勺制作的人工耳蜗头皮拉钩可行，疗效良好。“,”Objective To improve the success rate of cochlear implantation,prevent complications and optimize the op-erative process.Methods Stainless steel concave spoon was polished into a concave shape etractor and used in 120 ca-ses of cochlear implantation.Results The concave shape etractor could fully expose surgical field,avoid the friction of etractor and drill bits to decrease the wear of drill bit and metal scrap,reduce scalp tissue contusion,and conserve oper-atorsphysical strength.Conclusion Cochlear etractor made of stainless steel concave spoon is feasible and effective in cochlear implantation.
