Total ossiculoplasty with footplate removal.

OBJECTIVE

We reviewed the results and management of cases in which total ossiculoplasty requires footplate removal.

STUDY DESIGN AND

SETTING

We conducted a retrospective review of 10 patients who underwent total ossiculoplasty with footplate removal between 1999 and 2002. These 10 patients represented 5.4% of those undergoing stapedectomy (n = 91) and ossiculoplasty (n = 93) during these years at a tertiary otologic referral center.

RESULTS

A total of 10 patients were evaluated, with a mean 17-month follow-up. Closure of air-bone gap (ABG) to within 20 dB was achieved in 6 of 10 patients (60%). Mean postoperative ABG was 21.7 dB (500 to 4000 Hz) with an average 4-frequency pure tone improvement of 20.7 dB. Operative findings included extensive tympanosclerosis, partial obstruction of oval window by facial nerve, and changes from prior surgery. There were no patients with postoperative sensorineural hearing loss.

CONCLUSIONS

The need to open the footplate in cases of total ossiculoplasty is uncommon. This may be accomplished with good improvement in hearing with minimal risk.
