Objective: To review published scientific studies on the prevalence of vestibular disorders in patients with hearing loss, thereby suggesting appropriate vestibular tests and directions for future research. Result: Approximately 40 - 60% of patients with sensorineural hearing loss (SNHL) present vestibular abnormalities, commonly manifested as reduced vestibulo-ocular reflex, dysfunction of the utricle or saccule, and mild dizziness. Nearly 70% of children with SNHL show vestibular dysfunction, of whom 20 - 40% have severe bilateral vestibular impairment. About 40% of patients with idiopathic sudden sensorineural hearing loss (ISSHL) experience vestibular symptoms. In Ménière's disease, audiovestibular dysfunction is characteristic, with vertigo episodes lasting from 20 minutes to 12 hours. Additionally, 30 - 60% of patients demonstrate changes in vestibular function after cochlear implantation. Conclusion: Vestibular disorders are relatively common in patients with hearing loss but are often overlooked. Incorporating vestibular examination into the routine assessment of hearing-loss patients may provide more comprehensive diagnosis and improve treatment outcomes.
