The introduction of clinical electric response audiometry has greatly assisted in the analysis and differential diagnosis of hearing disorders. A similar development regarding the analysis of balance disorders has been lacking.
We are still having difficulties to assess directly a peripheral vestibular organ without the possible interference from other sensory modalities, and despite growing contributions from electro-nystagmography, vestibular evoked myogenic potentials, vestibular brainstem and cortical responses.
In the following video (follow link below) it is demonstrated that extratympanic electro-cochleography techniques can be applied to specifically examine the peripheral vestibular organ, and in particular the otolithic organ. Following head tilt stimulation in roll and in pitch, analogue data are collected with an electrode placed in the tympanic recess. Raw digitized and then analysed data can be presented in a visual format enabling the physician interpretation at a glance.
