Background: Hearing is vital for communication, and sensorineural hearing loss (SNHL) can result from inner ear or nerve damage. Hypothyroidism, a condition with low thyroid hormone levels, may be a contributing factor to SNHL. This study compares SNHL prevalence between hypothyroid and non-hypothyroid patients. Methodology: A cross sectional comparative study, among 40 hypothyroid patients were compared with 40 age controls for their hearing acuity was conducted at tertiary care hospital, Sullia between March 2025 and august 2025 to evaluate prevalence of SNHL among hypothyroid patients visiting the outpatient department of ENT and/MEDICINE/GENERAL SURGERY. Results: The majority of participants were women (77.5%), mostly aged 30–40 years. Among hypothyroid patients, 60% had normal hearing, while 40% had SNHL, compared to 77.5% and 7.5% respectively in controls. Conductive and mixed hearing losses were less common, with most cases showing mild hearing loss. Conclusion: Hypothyroid patients showed a predominance of sensorineural hearing loss, followed by conductive and mixed types, mostly of minimal to mild severity. Severity increased with longer disease duration, highlighting the need for early detection. Pure tone audiometry is recommended to raise awareness and support early diagnosis and prevention.
