It is important to conduct not only vestibular but also audiological examinations in patients complaining of dizziness who develop sudden deafness and Meniere's disease. The differential diagnosis among kinds of sudden deafness involves distinguishing among perilymphatic leak, acoustic neuroma, and Meniere's disease.
We also discuss the incidence of dizziness or vertig o, as well as that of spontaneous nystagmus during ENG, in patients with sudden deafness; the importance of dizziness and of disturbance of balance; the results of the glycerol test in patients with sudden deafness with low-tone hearing loss; and the diagnosis of progressive hearing loss with sense of occlusion.
Tests of hearing loss and tinnitus, in particular the glycerol loading tinnitus test, are useful in the diagnosis of Meniere's disease.
The combined application of the auditory brainstem response test with equilibrium tests, especially the damped pendular rotation test, is useful in the diagnosis of central vestibular disorders.
