[Dehydration therapy in low tone hearing loss. An alternative to rheologic therapy?].

Patients with acute low-tone sensorineural hearing loss were treated by rheology or dehydration after recording of the summation and compound action potentials by electrocochleography. Patients treated in the acute phase, as well as patients with chronic disease (that is the interval between onset of hearing loss and therapy was more than 1 week) clearly responded better to dehydration than to conventional rheological treatment. This was especially striking in those patients showing an enhanced SP/AP ratio indicating endolymphatic hydrops.
