The caloric vestibular test in weightlessness

Archives of Oto-Rhino-Laryngology, 1987
Although the theoretical background for the caloric vestibular test was assumed to be known, recent studies in weightlessness have thrown doubts on the original theory of its mechanism. It is most likely that several mechanisms are involved in the generation of caloric nystagmus in addition to the convection current theory. Experiments with the caloric

Caloric Tests In Deaf Children

Archives of Otolaryngology - Head and Neck Surgery, 1965
T THERE ARE only a few reports in the literature concerning the vestibular reactivity in children that suffer from severe sensorineural impairment of hearing. Shambaugh et al 13 collected, in 1930, information about 5,348 children from schools for the deaf in the US.

Evaluation of the monothermal caloric test

The Laryngoscope, 1989
AbstractIn 1970, Torok reported that patients with labyrinthine disease showed vestibular recruitment and that patients with retrolabyrinthine disease showed vestibular decruitment on the monothermal caloric test. Other investigators have failed to confirm these findings; however, their studies did not precisely replicate Torok's test procedure ...

A microbiological hazard in caloric testing

British Journal of Audiology, 1991
The use of caloric testing is widespread in hospital audiology departments. This paper describes contamination of the caloric water tanks with the organism Acinetobacter anitratus and the changes in practice instituted to eliminate this risk to patients.

The ice-water caloric test

Acta Oto-Laryngologica, 2009
Three possible results are commonly seen after ice-water caloric irrigation and to correctly interpret them the function of the corresponding vestibular receptor and of normal endolymphatic flow must be taken into account. Bedside vestibular examination helps to interpret discrepant findings.To review the findings obtained with the ice-water caloric ...

A Protocol for the Air Caloric Test and a Comparison With a Standard Water Caloric Test

Archives of Otolaryngology - Head and Neck Surgery, 1979
This communication describes the development of a protocol for the air caloric stimulus for vestibular testing. The protocol is based on matching the peak responses of air and water caloric stimuli and minimizing subject discomfort. Air stimulus temperatures of 30 and 44 degrees C are used, and these appear to minimize subject complaints of pain with ...

A Simple Quantitative Caloric Test

Archives of Otolaryngology - Head and Neck Surgery, 1958
In a recent article, Hitschler 2 described a simple caloric test in which he used water at a constant temperature (36-37 F) for a definite period of time (5 seconds). He stated that the time during which the water is in contact with the eardrum is the important factor, not the amount of water, and that severe reactions are uncommon in this procedure ...

Screening methods for caloric testing

Clinical Otolaryngology, 1987
In order to evaluate the screening capacity and the reliability of monothermal caloric stimulation, the caloric results obtained in 272 patients have been reviewed. The results of a complete bithermal 4-test-set are compared with the results of the hot and cold stimulation considered separately.

Simplification of Clinical Caloric Test

Archives of Otolaryngology - Head and Neck Surgery, 1965
THE FACT that thermic stimuli, when applied to the external auditory canal, could induce labyrinthine nystagmus was known by Brown-Sequard3as early as 1860, and Bornhardt2was the first to apply this knowledge experimentally by inducing caloric stimulation of the semicircular canals of pigeons.

[Air caloric test: as useful as the water caloric test (author's transl)].

Laryngologie, Rhinologie, Otologie, 1979
Twenty normal probands were examined by us with air (60 sec, 121/min, 45 degrees/29 degrees C) and 25 with water (30 sec, 30 cm3, 44 degrees/30 degrees C) caloric test. Additionally we evaluated the influence of flow rate and tip position on the temperature near the tympanic membrane during the irrigation, using a polyacryl copy of the external ...
