A questionnaire survey was conducted to investigate the relative comfo
rt of a comprehensive range of diagnostic procedures. The mean comfort
ranking and variability in comfort were examined. Pure tone audiometr
y and speech audiometry are the most comfortable tests, while caloric
testing and transtympanic electrocochleography are the least comfortab
le. However, caloric testing and glycerol dehydration are not signific
antly different in comfort to magnetic resonance imaging (MRI), and br
ainstem evoked response testing is more comfortable than other diagnos
tic tests, including MRI. The reasons for these differences and the im
plications for diagnostic management are discussed.
