ABSTRACT
Aims & objective: the objective of present study was to assess the hearing loss in patients of diabetes mellitus type II by clinical and audiometric examinations.
Material and methods: this prospective study was done in the department of ENT, Pacific Medical College and Hospital, Udaipur during the period from January 2016 to January 2018. 100 cases of diabetes mellitus type II were included in the study. 100 healthy were included in the study as controls. Complete routine and audiological investigations were done in all the subjects including audiogram, acoustic reflex, tone decay test, speech discrimination score and short increment sensitivity index score and the results were compared between cases and controls.
Results: the study includes 100 diabetic cases with mean age 52.5 (age ranges from 40-60 years). Cases include 74 males and 26 females. 100 healthy controls were included with mean age 53.1. Age and sex were matched with cases. Prevalence of hearing loss was 46% in cases and 11% in controls. Hearing loss in all the subject was of sensorineural type (SNHL). Among cases, 3 patients had unilateral and 43 cases had bilateral hearing loss. All the 11 controls had bilateral hearing loss. 26 diabetic cases had mild SNHL while 20 patients had moderate SNHL. 7 controls had mild SNHL and 4 controls had moderate SNHL.
Conclusion: SNHL is an established complication of diabetes. Diabetes basically accelerates the senile changes occurring at the level of cochlea, thus increasing the prevalence of hearing loss. Based on present study, we could recommend the audiological screening of all the diabetic patients.
