Abstract：Objective To analyze the effect of tympanic membrane repair under the ear endoscope on pure tone threshold,incidence of complications,and efficacy in patients with chronic otitis media(COM)tympanic mem-brane perforation.Methods The study included 68 patients with COM tympanic membrane perforation treated at the Department of Otolaryngology of Jiang County People's Hospital from December 2019 to December 2023.Ac-cording to different surgical methods,they were divided into the observation group and the control group,with 34 cases in each group.The observation group underwent tympanic membrane repair under the ear endoscope,while the control group underwent tympanic membrane repair under the microscope.The surgical operation time,intraop-erative blood loss,tympanic membrane healing rate,dry ear rate,pure tone threshold,incidence of complications,and quality of life were compared between the two groups.Results In the observation group,the operation time was shorter than that in the control group,the intraoperative blood loss was lower than that in the control group,and the tympanic membrane healing rate and dry ear rate were higher than those in the control group,with statisti-cally significant differences(P＜0.05).There were no statistically significant differences in air-conduction threshold,bone-conduction threshold,and air-bone gap between the two groups at 3 and 6 months after treatment(P＞0.05).The incidence of complications in the control group and the observation group was 14.71％(5/34)and 0.00％(0/34),respectively.After surgery,the ear symptoms,subjective hearing level,psychological status,and medical resource utilization scores in both groups were significantly reduced,while the observation group showing lower scores than the scores of control group,and statistically significant differences(P＜0.05).Conclusion Tympanic membrane repair under the ear endoscope can improve pure tone threshold,is safe,and is a good surgical method for treating patients with COM.
