Background: Fibromyalgia (FM) is a non-inflammatory musculoskeletal chronic syndrome, whose etiology is unknown, characterized by diffuse pain, many patients with FM were reported to have dizziness which is attributed to hypotension and the autonomic nervous system (ANS) dysfunction. Aim: To improve management of patients with fibromyalgia having dizziness. Objective: to assess peripheral vestibular functions in patients with fibromyalgia. Subjects and Methods: After obtaining approval from the Ethics Committee of the Suez Canal University Hospital (registration number:3646) and written informed patient consent, a Cross-sectional study was conducted at Suez Canal University hospital from June 2018 to December 2019 in the Audio-Vestibular Clinic of the E.N.T department, including 30 female subjects whose age ranged from 22 to 50 years and were divided into Study group that comprised patients diagnosed with fibromyalgia and Control group rather healthy individuals. The vestibular assessment was done using pure tone audiometry, Bedside tests, and video-nystagmography (VNG). Results: There was no statistically significant difference between both groups regarding results of bedside examinations and VNG results as a caloric test (p-value = 0.6) however, there was a trend towards positive results and an increase in vestibular weakness in the fibromyalgia group compared to the control group. Conclusion: Fibromyalgia is unlikely to be a cause of peripheral vestibular dysfunction, so vestibular testing is not routinely recommended for such patients.
