Ossiculoplasty is the surgical restoration/rehabilitation of patients with conductive hearing loss secondary to ossicular dysfunction. This dysfunction manifests as conductive hearing loss and can be the result of congenital causes, or result secondarily as the result of cholesteatoma, tympanosclerosis, or otosclerosis. This module focuses on anatomic and embryologic considerations in ossiculoplasty and ossicular malformations as well as surgical considerations. Otosclerosis and stapedotomy are discussed in detail in another module.
