Bilateral Malleus Ankylosis: a Case Report

Malleus ankylosis known as House syndrome is very rare. It represents 38.1% of congenital malformation of the middle ear [1] if stapes ankylosis is associated. We have report a case of bilateral Malleus ankylosis without stapes ankylosis. That's make our study interesting because it's very rare and it's rarely described in the literature. Clinically, it's reveal by a congenital conductive hearing loss bilateral isolated, without vertigo or tinnitus, and normal otoscopy exam. Normal ear drums. Ct scan is the main exam for visualization of ossicular chain and research others anomalies. The diagnosis is confirmed during surgery. The surgery consists of an ossiculoplasty, by section of the Malleus neck with interposition with Incus. Stapes has normal mobility without ankylosis. We got good result by gain of 20 db in the principal frequency after 3 mounts. Our patient is satisfied. The other side will be programmed one year later.
