| Barany | Robert, Austrian-Hungarian otologist and Nobel laureate, 1876-1936. See: Barany's sign, Barany's caloric test, positional vertigo of Barany. (05 Mar 2000) |
| Barany's caloric test | A test for vestibular function, made by irrigating the external auditory meatus with either hot or cold water; this normally causes stimulation of the vestibular apparatus, resulting in nystagmus and past-pointing; in vestibular disease, the response may be reduced or absent. Synonym: caloric test, nystagmus test. (05 Mar 2000) |
| Barany's sign | <clinical sign> In cases of ear disease, in which the vestibule is healthy, injection into the external auditory canal of water below the body temperature (18°C or lower) will cause rotary nystagmus toward the opposite side; when the injected fluid is above the body temperature (41°C or higher) the nystagmus will be toward the injected side; if the labyrinth is diseased or nonfunctional there may be diminished or absent nystagmus. (05 Mar 2000) |
| positional vertigo of Barany | Brief attacks of paroxysmal vertigo and nystagmus that occur solely with certain head movements or positions, e.g., with neck extension; due to labyrinthine dysfunction. Synonym: positional vertigo of Barany, postural vertigo. (05 Mar 2000) |
