Objective: Assess the prevalence of the risk of sleep disorders in patients with dizziness and vestibular symptoms in patients with sleep disorders.Method: Perfoming a cross-sectional study that included adult patients treated at the first consultation at the clinic of the Discipline of Otology and Neurotology (group 1) and Sleep Apnea ambulatory in the Department of Sleep Medicine (group 2) from UNIFESP and applying questionnaires about vestibular complaints and validated questionnaires on the risk of sleep disturbances.Results: Group 1 consisted of 24 patients, being 83.3% female, with mean age of 47.08 years. In assessing the risk for sleep disorders, 54.2% were at high risk according to the Berlin scale, 66.7% were at risk by the Pittsburgh scale, and 41.7% were at risk by the Epworth Sleepiness Scale. The second group was represented by 18 patients, being 77.8% male, with a mean age of 49.67 years. As for the vestibular symptoms, 44.4% reported dizziness, being vertigo in 22.2% of the cases and 22.2% with worsening at head movement. Conclusion:There is a high prevalence of the risk of sleep disorders in patients with dizziness and vestibular symptoms in patients with sleep disorders. Method: Nine ear plugs were inserted in random order in ears of 10 healthy subjects. Three standardized head wetting protocols were instructed: surface swimming, upright head submersion to apply horizontal pressure, and 90 degrees tilted head submersion to apply vertical pressure. Color change in moisture indicator was evaluated after each protocol. Otology/Neurotology
