Bá·rá·ny sign

(bah'rah-nē),
in cases of ear disease, in which the vestibule is healthy, injection into the external auditory canal of water below the body temperature will cause rotatory nystagmus toward the opposite side; when the injected fluid is above the body temperature the nystagmus will be toward the injected side; if the labyrinth is diseased or nonfunctional there may be diminished or absent nystagmus.

Bárány sign
