The definitive diagnosis of perilymph fistulas can be made only by tympanotomy, and previous attempts to record vestibular abnormalities based on eye movement recordings have been of limited value because of the inability to isolate vestibular reflexes from visual and proprioceptive contributions to body muscle control. In the past, therefore, tests for suspected perilymph fistulas yielded unacceptably high false—negative and false—positive test results.

At the meeting, F. Owen Black, MD, and associates David J. Lilly, PhD, Lewis M. Nashner, DSc, and Robert J. Peterka, PhD, Neurological Sciences Institute, Good Samaritan Hospital and Medical Center, Portland, Ore, reported that a new fistula test based on vestibulospinal reflexes has been developed. This test is based on vestibulospinal responses to sinusoidally modulated air pressures within the external auditory canal. During this test, vision and support-surface orientation references are removed systematically from a standing patient. With only vestibular control of posture available, patients with . . .
