Abstract

Background: Asymmetrical sensorineural hearing loss (ASNHL) is an important finding in audio-vestibular units as it has many underlying causes, such as Meniere's disease, retro-cochlear lesions, autoimmune disorders, and noise exposure. Aim and objectives: To assess the vestibular function of patients with ASNHL and to know whether it can be related to subclinical vestibular weakness or Meniere's disease. Patients and methods: This cross-sectional study was conducted on 40 cases from October 2023 to August 2024 at the Audio-vestibular unit, ENT Department at Al-Hussein University Hospital. Results: Results showed that unilateral vestibular weakness was discovered in 51.3% of ASNHL cases, even without vertigo, and it was related to the worse hearing side. Conclusion: Silent vestibulopathy can be found in many cases of ASNHL patients, and there is a positive correlation between vestibular weakness and the degree of hearing loss.
