A prospective, observational study of incidence of sensory neural hearing loss in diabetes mellitus patients

Aims and Objective: To find out the incidence of hearing loss among the type 2 diabetes mellitus patients. Materials and Methods: Study included 100 diabetic mellitus patients at least for 3 years. It is an observational study carried out for 1 year. Fasting blood sugar, PP2BS, random blood sugar, pure tone audiogram were done. Results: In this study, 100 diabetic patients were studied; out of them, 73 patients were having sensorineural hearing loss (SNHL). Out of 73 SNHL diabetic patients, 48 patients are having mild SNHL (65.75%), 21 patients are having moderate SNHL (28.76%), one patient of mod severe SNHL (1.37%), and three patients of severe SNHL (4.11%). Conclusion: The diabetic individuals had higher hearing threshold with bilateral mild to moderate degree SNHL. Gender of diabetic patient had no significant correlation with hearing loss. Duration of diabetes had significant correlation with hearing loss. Blood glucose level had strong association with SNHL.
