Understanding the Dizzying Array of Diagnostic Dizziness Tests

Program Description:The “dizzy” patient can be a diagnostic challenge. Symptoms can be nonspecific and result from numerous etiologies. While most otolaryngologists realize that a complete and accurate history provides the basis for the diagnosis and management of balance disorders, the use and diagnostic significance of balance tests can be unclear. In this miniseminar, we will discuss the use and interpretation of a variety of balance tests including electrocorticography, vestibular evoked myogenic potential, videonystagmography testing, rotational chair testing, head impulse tests, and posturography. The goal of this miniseminar is to educate and discuss the use of these tests in a modern practice.Educational Objectives:(1) Identify history and physical examination findings that indicate the need for further diagnostic testing. (2) Decide which balance tests to order when further testing is necessary. (3) Interpret balance function testing for diagnostic and prognostic purposes.
