术中耳蜗电图监测在脑桥小脑角区胆脂瘤切除术中的应用
Application of intraoperative cochlear electroencephalography monitoring in resection of cholesteatoma in cerebellopontine angle region
摘要
Abstract
Objective To examine the relationship between intraoperative electrocochleography(ECoG)monitoring data and post-operative audiometric grading using American academy of otolaryngology-head and neck surgery(AAO-HNS)scale,as well as hearing handicap inventory(HHI)severity scores for hearing disability.Methods The clinical data of 86 patients with cerebellopontine angle(CPA)cholesteatoma admitted to Department of Neurosurgery,China-Japan Friendship Hospital from March 2019 to March 2022 were analyzed retrospectively.All patients underwent retrosigmoid approach surgery for CPA cholesteatoma removal,with intraoperative ECochG monitoring to ensure complete tumor resection.According to the intraoperative ECochG monitoring information,patients were divided into two groups based on whether the action potential(AP)drops over 30%or not.The AP drops>30%group and the AP drops≤30%group were used to analyze the relationship between the two groups and postoperative hearing impairment and the degree of hearing disability.Results Patients in the AP drops>30%group exhibited postoperative hearing impairment,and their hearing impairment persisted after 3 months,1 year,and 2 years of follow-up,with statistical differences(P<0.001).Patients with AP drops>30%had varying degrees of hearing disability after surgery.After follow-up for 3 months,1 year,and 2 years,patients'HHI subtotal emotional(subtotal-E)and subtotal situational(subtotal-S)related hearing disabilities persisted,with statistical differences(P<0.001).The degree of disability related to HHI subtotal-E and subtotal-S will gradually worsen,with statistical differences(P<0.05).Conclusions Patients with intraoperative AP drops>30%have permanent hearing impairment after CPA area cholesteatoma surgery,and their postoperative subtotal-E and subtotal-S related hearing disabilities will gradually worsen.关键词
