Design: This study used a descriptive cross-sectional research design to examine the relationship between unilateral idiopathic severe-to-profound sensorineural hearing loss and the vestibulo-ocular reflex. Study Sample: The study included 76 participants (42 women, 34 men) aged 18-50, comprising individuals with unilateral idiopathic severe-to-profound sensorineural hearing loss and healthy controls. All completed a Demographic Data Form and underwent v-HIT and f-HIT assessments. Results: The f-HIT revealed statistically significant differences among the affected ear, unaffected ear, and control groups in lateral SCC performance at 4000-6000 degrees/s(2), posterior SCC performance at 3000-6000 degrees/s(2) and in overall percentage of correct answers (%CA) (p < 0.05). The v-HIT showed significant group differences in VOR gain values for all SCCs and in asymmetry between case and control groups (p < 0.05). Conclusions: A decrease in the gain and functionality of the vestibulo-ocular reflex has been observed in individuals with unilateral idiopathic severe-to-profound sensorineural hearing loss. & Idot;nvolvement of the vestibulo-ocular reflex pathway has also been noted on the side without hearing loss.eninfo:eu-repo/semantics/closedAccessSensorineural hearing lossfunctional head impulse testvideo head impulse testvestibulo-ocular reflexvestibular systemArticle4169785610.1080/14992027.2026.26302842-s2.0-105030260359Q1WOS:001693351800001Q20000-0002-5842-31160000-0003-3399-7188
