Rotational vertigo or balance disorders can result from a peripheral lesion of the vestibular receptors or a central nervous system injury. An otoneurological assessment is needed to guide diagnosis towards a peripheral or central cause and to adapt treatment accordingly. Both functions of the inner ear should be explored: the auditory function and the vestibular function. Indeed, in addition to its role in the perception of sounds, the inner ear is essential in balancing and steadying the gaze when we move our head and body.
A complete examination can only be performed by a qualified otoneurologist using sophisticated apparatus.
The examination is performed using videonystagmography (VNG) goggles and by measuring evoked potentials induced by sounds and received either in the cervical region or the eyes. Balance disorders should be assessed using an EquiTest to ascertain the cause and choose the most appropriate treatment.
This otoneurological assessment will also help to determine the indication for imaging and specify the type of imaging required: scan of the pyramids or brain MRI focusing on the IAC.
This serves two purposes:
1) to determine the cause of the dizziness, vertigo or balance disorders,
2) to prescribe appropriate and effective treatment to help the patient’s life return to normal.
Prescribing unnecessary and potentially dangerous medication is a thing of the past.
