Clinical Classification Guidelines
Medical Intelligence & Overview
Unilateral sensorineural hearing loss (SNHL) is a condition where hearing loss occurs in one ear due to damage within the inner ear or nerve pathways to the brain. When this loss is accompanied by restricted hearing in the opposite ear, it can significantly affect hearing ability and quality of life. This article provides an overview of this specific condition classified under ICD-10 code H90.A2, exploring its causes, symptoms, diagnosis, and available treatment options.

Key Symptoms: Sudden or gradual loss of hearing in one ear Difficulty discerning speech, especially in noisy environments Feeling of fullness or pressure in the affected ear Tinnitus (ringing or buzzing sounds) in the affected ear Dizziness or imbalance in some cases Reduced ability to localize sound sources Perception of sound imbalance, with limited hearing on the opposite side
