Abstract: Objective To improve the success rate of cochlear implantation, prevent complications and optimize the operative process. Methods Stainless steel concave spoon was polished into a concave shape etractor and used in 120 cases 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 operators' physical strength. Conclusion Cochlear etractor made of stainless steel concave spoon is feasible and effective in cochlear implantation.

Key words: Cochlear implantation, Etractor, Concave shape spoon
