Congenital duplicated incus in the mastoid cavity

Abstract

Abstract Many congenital ossicular chain malformations exist, usually involving ossicular deformities, fixation, absence, or discontinuity. Duplication of ossicles has not been reported, much less a duplicated ossicle located in the mastoid. We present a case of a patient who had a duplicated incus in the mastoid antrum.
