Tinnitus is an otological symptom which is often encountered and is yet difficult to treat.
Transtympanic anesthesia with 1ml of 4% Lidocaine was performed in 86 patients (119 ears) suffering from cochlear tinninus.
The results are summarized as follows:
1) Tinnitus was completely abolished or considerably ameliorated in 37 ears (31%)
2) Tinnitus was moderately ameliorated in 52 ears (44%)
3) Tinnitus was slightly ameliorated in 30 ears (25%)
Consequently, we found the therapeutic effectiveness of the transtympanic anesthesia in 75% of our cases.
It is not elucidated whether the therapeutic effect of the transtympanic anesthesia was attributed to anesthetic blockade of the tympanic plexus or the inhibition of cochlear cell activity.
However, it is undeniable that the transtympanic anesthesia has a remarkable therapeutic effect to tinnitus without any significant side effects.
It is hoped that this therapeutic method would be used more often for the patients suffering from tinnitus.
