A 32-year-old female presented with a history of otorrhea and hearing loss in her right ear since 2 years. On examination, external auditory canal was found to be filled with polypoidal tissue along with mucopurulent discharge. Audiometry showed mixed hearing loss of 50, 55, and 60 dB with air-bone gap of 30, 35, and 40 dB at frequencies of 0.5, 1, and 2 kHz respectively. She was operated for the same, and biopsy was sent for histopathological examination, which showed granulomatous inflammation. The patient was treated with antituberculous therapy, and she responded fully to the treatment.

Objective: This study has been undertaken to study the effect of type II diabetes mellitus (T2DM) and its duration on hearing. Materials and methods:The present study was conducted on 100 persons of age group 20 to 45 years. All subjects included in the study were divided into two groups. Group I: 50 patients suffering from T2DM (fasting blood sugar ≥ 126 mg/dL and postprandial ≥ 200 mg/dL) of either sex, in the age group of 20 to 45 years. Group II: 50 healthy volunteers in the age group of 20 to 45 years, of either sex were included in control group. Hearing assessment was done by using pure tone audiometry (PTA). Results:In diabetic patients, the mean threshold in the PTA was higher at all frequencies as compared with healthy controls, and there was a positive correlation between the duration of diabetes and hearing loss. Conclusion:Various audiological investigations have revealed that there is a strong association of diabetes with sensorineural part. The prevalence of sensorineural hearing loss (SNHL) in type II diabetics observed was 64%. In the majority of the patients, the hearing loss was bilateral, affecting mid and higher frequencies from 2 to 8 kHz. Hence, to conclude, we can say that the high prevalence of hearing loss in T2DM supports the importance of audiometric evaluation in such patients.
