Comparison of Symptoms and Laboratory Findings in Unilateral Vestibular Dysfunction

Abstract

Although vertigo is the expected symptom of unilateral vestibular disease, exceptions have been observed. To determine the relative frequency of this observation, a retrospective study of patients seen over a 1-year period was done. Of the 126 patients found to have unilateral labyrinthine impairment with bithermal caloric testing, only 58 (46%) characterized their symptoms as vertigo. The ramifications of these findings are discussed, and a question is raised as to the propriety of reserving vestibular testing for only those patients describing vertigo.
