摘要：Introduction: Simultaneous exposure to certain chemical agents and noise may cause synergistic, additive or potentiating effects on the auditory and vestibular system. However, there is still a lack of studies investigating simultaneous exposure to pesticides and noise in the vestibular system. Purpose: To analyze the findings of the vestibular evaluation of endemic diseases combat agents when simultaneously exposed to pesticides and noise. Method: Thirty-three male pesticide-exposed and noise-fighting endemic diseases combat agents participated in the study. The age range was 48 to 67 years (mean = 56 years). All participants underwent vestibular examinations, such as positional nystagmus research, spontaneous nystagmus with open and closed eyes, semi-spontaneous nystagmus, optokinetic nystagmus, pendular screening, per rotatory, caloric tests and tonal audiometry. Data were analyzed by descriptive statistics. Results: Altered exams were presented in 36.4% of the cases. There was no statistically significant relationship between pesticide handling time and test results (p = 0.2825). The results of pure tone audiometry correlated significantly (p = 0.0494) with the vestibular exams, as participants who presented with worse hearing thresholds at the frequency of 4000 Hz in the right ear also presented altered results in the vestibular exam. Conclusion: The present study concluded that more than 1/3 of the studied population presented with vestibular dysfunction, which was related to anterior and posterior labyrinth alteration (Cochlear-Vestibular Syndrome). No central vestibular alteration was noted in this population.
