Extended caloric tests.

The standard ABB remains the most popular test of vestibular function. The use of air caloric irrigations or the closed loop water system seem to be scientifically sound alternatives to the use of open water irrigation. Although controversy still surrounds the use of monothermal warm calorics as a screening test, several studies have shown its reliability. The Torok monothermal differential caloric test seems to be a good alternative to the ABB, but more studies need to be done showing its results in other hands. Some of the other tests mentioned in this report may be helpful as ancillary tests for use in patients in whom the standard tests produce inconsistent findings.
