Background: To detect early onset of subclinical Hearing loss in Type 1 DM children. Materials & methods: 100 patients between age group of 6-17 years with confirmed diagnosis of Type 1 DM and an average disease duration of more than 1 year and 100 age and sex matched healthy controls. These children were subjected to an ENT examination and Audio logical assessment was done by Pure-tone average (PTA) and Otoacoustic Emissions (OAE). All selected patients with IDDM were examined in detail, which included detailed history and ENT examination. Hearing thresholds were assessed by pure tone audiometric test. Bone and air conductions thresholds were both tested at frequencies between 250-4000 Hz and 250-8000 Hz, respectively Results: Sensorineural hearing loss (SNHL) was seen in 10 percent of the subjects of the study group while it was absent in control group. A direct significant correlation of SNHL was seen with glycaemic profile. Conclusion: Hearing evaluation may form an important part of the standard management regimen for children with the disease.
