[Audiologic diagnosis of tumor-induced neural hearing disorders based on discrete finding constellations]

Modern electrophysiological and audiometric tests allow the cause of retrocochlear hearing loss to be diagnosed in almost all cases. Assessment of the stapedius reflex, discrimination using the Fowler test, the ERA findings with respect to inter-peak latency, interaural latency difference of the fifth wave, DORAS (difference between the objective response threshold and the subjective tone threshold), and finally the vestibular findings are all important.
