Carbamazepine in the treatment of objective myoclonus tinnitus

Three patients have had objective clicking tinnitus which was demonstrated by using impedance audiometry. Additionally EMG studies to localize the contracting muscle were performed, and EEG recordings to find the possible focal cortical activity. One patient had central nervous degenerative lesions. Carbamazepine was given as the treatment. The results are encouraging: in all cases the clicks have almost totally disappeared, making normal living possible. When medication was discontinued, the symptoms reappeared.
