Computed tomography of the disarticulated incus.
Complete incus disarticulation may be a complication of trauma, chronic otitis, or prosthetic stapedectomy. Purposeful incus disarticulation (with incus interposition) is used as a method of ossicular reconstruction. CT has been a valuable diagnostic tool for preoperative location of the incus in the former disorders and for determination of the status of the ossiculoplasty in the latter.
