Download

Caloric testing in a 59-year-old Moroccan man with bilateral posterior and right superior semicircular canal dehiscence. Right caloric hyporeflexia (canal paresis) is evident on the Freyss diagram (top center of figure), with a calculated deficit of 40% on the right and a normal reflectivity of 64.1°/s on the left. Image edited by Dr. Douglas J Lanska to improve exposure and contrast and minimize the color cast. (From: Andaloussi TB, Bouqes M, Ouattassi N, et al.
