Bilateral objective tinnitus secondary to congenital middle-ear myoclonus.

Subjective tinnitus (heard only by the patient) is a common otological complaint. Objective tinnitus (heard by the examiner as well as the patient) is extremely rare. There are only a few cases of objective tinnitus, secondary to middle-ear myoclonus, described in the literature. We present the case of a child with bilateral, congenital, objective tinnitus, secondary to middle-ear myoclonus, with otherwise normal hearing thresholds (250 Hz-8 kHz), and with no evidence of intra-cerebral or systemic disorders. No similar case has been reported in the world literature.
