[Treatment of tinnitus by Neolidocatone administered by iontophoresis into the middle ear].

The authors describe a possible therapeutic approach mitigating tinnitus. It is not causal treatment but only symptomatic and extends the group of methods which influence tinnitus. The authors describe their own experience with iontophoresis of the middle ear with Neolidocatone-a derivate of Lidocaine which was done with a SANOMATIC apparatus, using galvanic current 1.5 mA. In one third of the patients it proved possible to mitigate the tinnitus permanently, in the remaining patients it persisted in the original intensity. The group of patients was heterogeneous from idiopathic tinnitus without impaired hearing, patients with otosclerosis, cervicocranial syndrome to those with Ménière's disease. The cause of tinnitus did not influence the therapeutic results.
