Other Diagnostic Tests
Auditory system
Audiometry
- Tests of auditory system (hearing) function include pure-tone audiometry, speech audiometry, acoustic-reflex, electrocochleography (ECoG), otoacoustic emissions (OAE), and auditory brainstem response test (ABR; also known as BER, BSER, or BAER).
- More sensitive detection of hearing loss at specific frequencies
- Better test for speech discrimination (disproportionately affected in retrocochlear disease)
- Most useful for distinguishing cochlear vs. retrocochlear causes of peripheral lesion
- Detects sensorineural hearing loss in almost all cases acoustic neuroma
Vestibular system
- Tests of vestibular system (balance) function include electronystagmography (ENG), rotation tests, Caloric reflex test, and Computerized Dynamic Posturography (CDP).
- Carotid doppler (presence of TIAs)
- Dix-Hallpike maneuver
- Barany maneuver (less specific than Dix-Hallpike)
- Evaluation of hearing
