Relevance of Otopathological Findings in the Treatment of Dizzy Patients

Dizziness is a common symptom in disorders of the brain and the ear. In a retrospective study of 1,000 cases, dizziness is attributed to a peripheral disorder in 25%, to a CNS disorder in 46%, and to undetermined causes in 29% of the cases. Peripheral disorders can be defined in terms of histopathological changes; the most frequent is cupulolithiasis, followed by endolymphatic hydrops and vestibular neuritis. These vestibular disorders are reviewed and discussed in connection with accepted facts and current hypotheses.
