Caloric Test with Air: Preliminary Report

Abstract

The author has constructed a thermoregulable air-blow apparatus, by which a caloric test can be performed. As subjects have been used persons with normal ears and patients with perforations in the tympanic membrane. The results have been compared with the usual caloric tests after Hallpike made by cold and warm water. The results show that a caloric test reliably can he made by air. Special attention is paid to different error possibilities.
