Đặc điểm thính lực trên bệnh nhân đái tháo đường type 2 tại Bệnh viện Nguyễn Tri Phương từ 2022-2023

Abstract

Background: The relationship between Diabetes Mellitus (DM) and sensorineural hearing loss (SNHL) has been acknowledged for decades. Hyperglycemia has an effect on hearing acuity and the proposed mechanisms are primarily microangiopathy. Objective: To compare pure tone audiometric results between type 2 DM patients and non-DM patients and to evaluate the effect of various factors related to SNHL. Methods: A cross section study includes 70 type 2 DM patients enrolled in this study, compared with 71 age- and sex-matched controls at Endocrinology and Otorhinolaryngology Department Nguyen Tri Phuong Hospital, Ho Chi Minh City, Viet Nam. Results: SNHL is prevalent in 77,1% of type 2 DM patients, among them has mainly slight hearing loss. The auditory thresholds in type DM group were higher in all age groups in all frequencies, especially high frequencies. Complicated and poorly controlled diabetes, >10 years duration have significant degree of hearing loss in high frequencies when compared with those who well controlled, uncomplicated, <10 years duration of diabetes. Conclusion: There was a correlation between type 2 DM and hearing threshold levels especially at higher frequencies. Some factors encompassing uncontrolled DM, long duration and complications of DM indicate the presence of early hearing loss on these patients.
