title: [Surgery for tympanosclerotic stapes fixation accompanied by malleus fixation at the anterior malleus: report of 2 cases].
abstract: Most tympanosclerotic stapes fixation involves fixation or erosion of the malleus and/or incus. This status of the ossicular chain is one reason that ossiculoplasty for tympanosclerotic stapes fixation is more difficult than that for otosclerosis. In some cases, the malleus is fixed only at the anterior, while the incus is intact. In such cases, anterior spinotomy can recover mobilization of the malleus, then a prosthesis can be used for the long process of the incus during ossiculoplasty. We conducted stapedectomy with anterior spinotomy on 3 ears in 2 patients. Over 15 dB of hearing was regained in all 3 ears 6 months after surgery. No significant sensorineural hearing loss was seen in any ear. To adapt this surgical procedure, it is necessary to evaluate preoperative CT findings and the status of the ossicular chain during surgery.
