To study role of glycosylated hemoglobin in hearing complication of diabetes

Introduction: Diabetes mellitus has been implicated as independent causative factor of bilateral sensorineural hearing loss. Diabetes-related sensorineural hearing impairment affects people’s ability to hear and understand sounds. This is a case control study with the purpose of determining the hearing loss in type II diabetes mellitus in relation to control of diabetes. Method: 50 diabetic patients and 50 age and sex matched controls who have satisfied inclusion and exclusion criteria and have consented to participate in study were enrolled. They were evaluated by Tuning fork tests and Pure Tone Audiometry. Result: The hearing of diabetics was significantly impaired than the non-diabetic control group. This hearing impairment was noted in all the frequencies tested. The hearing acuity was compared with control of diabetes. The hearing loss was highly significant in uncontrolled diabetics when compared with subjects having controlled diabetes. Conclusion: Type 2 diabetes causes significant hearing loss in the patients, and control of diabetes is also a highly significant cause of hearing loss.
