MAKING DIAGNOSIS OF MENIERE'S DISEASE: DEHYDRATION AND BALANCE TESTS

Dehydration tests
Based on the fact that there is an excess of endolymph in many cases with Meniere's disease, dehydration tests using diuretics (fluid tablets), glycerol or urea are frequently performed on patients. The changes effected by the administration of a diuretic may be measured using either traditional audiometric measures or electrocochleography. An improvement in pure tone hearing thresholds, speech discrimination scores or even abolition of the distortion during electro-cochleography confirms the diagnosis of endolymphatic hydrops.

Balance tests
Irritation in, or weakness of the vestibular system may show in an assessment and recording of the eye movement that occurs in response to head movement, body movement, rotation or temperature stimulation of the ears. This assists in measuring the degree of impairment of each ear with respect to balance.
Electronystagmography (E.N.G.) and harmonic acceleration tests using the rotating chair are two tests which can be used to assess the level of balance lost and the brain's compensation to the damage in the ear.
Sometimes it seems that a lot of time and money is spent on testing, but the importance of making a conclusive diagnosis as early as possible is vital. Not only does it rule out the presence of other unrelated conditions, including infections, tumours and neurological diseases, but it gives a greater chance of success in using drug therapy and other strategies for conservation of hearing and control of vertigo.
