Sponsor's own description
Severe-to-profound hearing loss can have a major impact on patients´ lives leading to social isolation and decreased quality of life. Most commonly the hearing loss is caused by damage to the inner ear or cochlear nerve. Since the vestibular system which is central for our balance is located in the inner ear it can be suspected that patients with severe-to-profound hearing loss also might have an impaired vestibular function. This impairment may lead to a feeling of dizziness or vertigo. This study aims to investigate if patients with severe-to-profound hearing loss also have impaired vestibular function. The vestibular function will be measured with caloric irrigation, video head impulse test and vestibular evoked myogenic potential.
