ABSTRACT:
A method of caloric vestibular testing comprises inserting an inflatable receptacle into an ear canal; admitting pressurized calorized fluid into the receptacle to cause its expansion laterally within the ear canal and longitudinally up to the tympanic membrane, such expansion filling the cross-sectional area of at least a portion of the ear canal; while inflating the receptacle, venting air trapped between the receptacle and the tympanic membrane to atmosphere; and circulating a volume of calorized liquid through the receptacle while carrying out a caloric vestibular function testing procedure.
