Objective tinnitus associated with essential laryngeal myoclonus: report of two cases.
We report on two patients with an objective tinnitus. In the first one, the objective tinnitus was unique as it was due to bilateral rhythmic contractions of the vocal cords. In the second, the objective tinnitus arose from Eustachian tube contractions and was associated with up and down movements of the larynx. In both patients, the abnormal laryngeal movement shared most of the characteristics of palatal or palatolaryngeal myoclonus and was thought to be laryngeal myoclonus. Its origin remained essential as all the investigations were negative.
