An organic phosphate insecticide poisoning is described, and the otologic findings elaborated. Disturbances of equilibrium were observed through a four-month period and documented by electronystagmography. Although damage of the central vestibular system was found, subjective complaints by the patient resolved completely within four months of the poisoning. However, thereafter both positional nystagmus and nystagmus after passive movements of the head could be observed. During the entire study period, neither hearing loss nor tinnitus occurred. After a review of the literature, the disturbances of equilibrium were designated as a sequela of the organic phosphate insecticide poisoning.
