Abstract：Objective By comparing patients with residual hearing,the difference of the mean value of pure sound hearing threshold between 250 Hz,500 Hz,1 KHz and 2 KHz before,one year and two years after cochlear implantation was compared to explore how to protect residual hearing.Methods 32 patients with cochlear implantation in the First Affiliated Hospital of Anhui Medical University from January 2020 to December 2021 were selected as research objects.Through regular follow-up,the pure sound hearing threshold values were compared before and one and two years after surgery,so as to evaluate whether the residual hearing was preserved after surgery.Results After surgery,two patients with large vestibular aqueduct syndrome had obvious vertigo symptoms,which improved after symptomatic treatment such as hormone and anti-vertigo.One year after surgery,the 250,500,1000 and 2000 Hz were higher than before surgery,and the difference was statistically significant(P＜0.001);At two years after surgery,the 2000 Hz pure tone threshold was higher than at 1 year after surgery,and the difference was statistically significant(P＜0.05).250,500,1000 Hz at 2 years after surgery were compared with one year after surgery,and there was no statistically significant difference(P＞0.05).Conclusion During the operation,the"soft"operation method can be used,so as to retain the residual hearing as far as possible,so that patients can make good use of residual hearing after cochlear implant.
