Utility of Screening Audiometry in Early Detection of Age-Related Sensorineural Hearing Loss in Geriatric Patients
Background: Age-related sensorineural hearing loss (presbycusis) is a prevalent and often underdiagnosed condition in the elderly, leading to communication difficulties and social isolation. Early identification through screening audiometry may enable timely intervention and rehabilitation. Material and Methods: This hospital-based cross-sectional study was conducted on 156 geriatric participants aged ≥60 years attending the Otorhinolaryngology outpatient department. Individuals with middle ear pathology, prior ear surgery, or exposure to ototoxic agents were excluded. Detailed demographic data were recorded, and each participant underwent otologic examination, screening audiometry, and pure tone audiometry (PTA). Hearing thresholds were classified according to the WHO criteria. The diagnostic performance of screening audiometry was evaluated against PTA, and age-related changes in hearing thresholds were analyzed. Results: Among the participants, 43.6% were aged 60–69 years, 37.2% were 70–79 years, and 19.2% were ≥80 years. Males constituted 57.7% of the study population. Hypertension (56.4%) and diabetes mellitus (41.0%) were the most common comorbidities. Based on PTA, 39.1% of ears had normal hearing, while the remaining exhibited varying degrees of hearing loss, predominantly mild and moderate. Screening audiometry showed a sensitivity of 91.6%, specificity of 88.5%, positive predictive value of 92.6%, and negative predictive value of 87.1% when compared with PTA. Mean hearing thresholds increased progressively with age, and the correlation between age and degree of hearing loss was statistically significant (p < 0.01). Conclusion: Age-related hearing loss is highly prevalent among the elderly. Screening audiometry demonstrates high diagnostic accuracy and can serve as a practical tool for early detection, facilitating timely auditory rehabilitation and improved quality of life.
