Fishing, one of the oldest productive activities, is an important sector of the Brazilian economy as well as the world economy. To evaluate the vestibular behavior in population of fishermen. It was realized as a retrospective and cross-sectional study. Thirty fishermen [mean age 49.5 (±8.5) years] whose age ranged from 33 years to 67 years were submitted to anamnesis, otorhinolaryngological evaluation, and vestibular examination through the electronystagmography (ENG). The most evident otoneurological symptoms were: Tinnitus (66.7%), dizziness (63.3%), and hearing loss (53.3%). The most evident clinical symptoms were: Fatigue (36.7%), anxiety (23.3%), and depression (16.7%). There were alterations in the vestibular examination of 13 (43.3%) fishermen in the caloric test. There was a prevalence of alteration in the peripheral vestibular system and there was a major frequency of the peripheral vestibular irritative syndrome (30.0%). Conclusion: The otoneurological complaints were frequent in the population studied that verifies the importance of allowing labyrinth examinations and the need for adopting preventive measures related to noise exposure to carbon monoxide (CO), since they can cause and/enhance various manifestations of labyrinthine vestibular impairment that can affect the quality of life of these workers.
