Introduction: Hypertension i.e blood pressure that is higher than normal causes hearing loss by various mechanisms of which, increase in the viscosity of blood causing hypoxia which inevitably results in target organ damage over a period of time which results in hearing loss is widely accepted. Aim: To assess the relationship between grades of hypertension and sensorineural hearing loss. Material and methods: This was a cohort study conducted at a tertiary care hospital over a period of 4 months from November 2022 to February 2023 at the department of ENT and the outpatient department of general medicine. A total of 104 patients aged between 45 to 65 who were currently on treatment were included in the study. Blood pressure was measured using a standard mercury sphygmomanometer with an adult cuff size, 6 hours apart, on two different occasions in sitting position. Hearing threshold was assessed using a pure tone audiometry in both the ears. Results: Based on the type of sensory neural hearing loss, patients were separated into five groups out of which patients with mild degree of sensorineural hearing was 12% patients, that with moderate degree was 24% patients, that with moderately severe sensorineural hearing loss was 12% patients, that with severe sensorineural hearing loss was 16% patients and profound sensorineural hearing loss was 6% patients. Conclusion: This study helped to assess the association between grades of hypertension and sensory neural hearing loss in hypertensives patients. Microcirculatory insufficiency might be the cause for it.
