 Malleus bar is a rare malformation of the ossicles characterized by a bony connection extending from the manubrium of the malleus at the posterior lip to the posterior wall of the tympanic cavity. In many cases, the removal of the bony connection improves conductive hearing loss. Herein, we report a case of a Malleus bar with tympanic nerve invasion in a patient with hearing loss that showed improvement after surgery.
