[Objective tinnitus caused by myoclonus of the musculus tensor veli palitini].

Objective tinnitus is often caused by palatal myoclonus. We report a 15 years old boy with objective tinnitus in both ears and palatal myoclonus. He had myorhythmic movements of both tensor veli palatini muscles asynchronous with the objective tinnitus. The frequency of the clonus was 120 contractions a minute. The myoclonus and the objective tinnitus disappeared after division of the bilateral tensor veli palatini muscles.
