  • Abstract
  • Look Inside

Effects of the anesthesia of the inner ear for treatment of tinnitus were studied in 22 patients by perfusion of 4% xylocain into the tympanic cavity through the tympanic membrane. The majority of the cases were accompanied by peripheral vestibular lesion, except in 4 who appeared to be free of such symptoms. The degree of tinnitus was evaluated by subjective symptoms as well as by tinnitus masking level measured by pure tone audiometry.

In 3 cases the tinnitus and vertigo were, both, totally reduced by perfusion for more than 24 hours; reduction of loudness was obtained in another 3 cases. No effect of the treatment was seen in 16 cases.

Clinical evaluation of the treatment showed that it was effective in 6 cases; 2 cases showed irritable stage of Ménière's disease and 4 cases were involved with paroxymal positional nystagmus with cochlear symptoms.
