Abstract

Two hundred and sixty patients tested with electronystagmography (ENG) for evaluation of complaints of disequilibrium were the representative sample for this study. As all new dizzy patients currently receive an ENG, the goal of this project was to determine how much an ENG adds to the diagnostic acumen, and which patients really needed an ENG in order to maximize efficiency and minimize patient cost. Results indicate the suspected diagnosis prior to ENG is assisted by its use only when the cause is thought to be central or is uncertain. The percentage of unknown causes of disequilibrium decreased from 34.2 to 13.8 per cent and the percentage of central causes increased from 13.1 to 23.1 per cent. Electronystagmography does not significantly aid in the diagnosis of peripheral lesions except as confirmation. Specific findings and recommendations are discussed.
