Necrosis of the incus by the chorda tympani nerve.
Ossicular necrosis is often associated with chronic adhesive otitis media. An unusual abnormality discovered in an incus removed during tympanoplasty is reported. The long process appears to have been grooved by pressure from the chorda tympani. An alternative theory to explain the vulnerability of the long process of the incus is suggested.
