Comparison of clinical effect of two methods for cholesteatoma of external auditory canal / 中国内镜杂志

ABSTRACT

Objective To compare the surgical results of cholesteatoma of external auditory canal under the otoscope and the microscope.Methods Clinical data of 44 patients with cholesteatoma from January 2015 to December 2019 were analyzed retrospectively.According to the operation mode,the patients were divided into observation group and control group.The cholesteatoma in the observation group was cleaned under the otoscope,and the cholesteatoma in the control group was cleaned under the microscope.The clinical effects of the two groups were compared.Results The patients in both groups were cured and their hearing was improved in different degrees.Compared with the control group,the difference of speech frequency hearing threshold between the observation group and the control group was statistically significant(t = 19.71,t = 13.41,P＜0.05).The operation time of the observation group was short than that of the control group,and the local discomfort of the observation group was lighter than that of the control group after operation,which was statistically significant(t =-3.68,t =-2.44,P＜0.05).All the patients were followed up for 6 months with dry ears and no recurrence.Conclusion Endoscopic treatment of cholesteatoma of external auditory canal is simple and effective,which is worthy of clinical application.
