Abstract:
BACKGROUND AND OBJECTIVES: The aim of this study was to analyze the results of malleostapedotomy as primary surgical procedure in stapes fixation. SUBJECTS AND METHOD: This study was a retrospective chart review of 12 patients who underwent primary malleostapedotomy for conductive hearing loss. The intraoperative findings, surgical outcomes including audiologic data and complications were analyzed. RESULTS: Nine patients had ossicular fixation with ossicular anomalies and 3 patients had ossicular fixation alone. The median length of piston wire was 5.5 mm in total length. The preoperative mean bone and air-conduction thresholds were 57.5+/-8.8 (mean+/-SD) dB, 19.7+/-10.3 dB, respectively, and the mean air-bone gap (ABG) was 44.6+/-13.2 dB. After malleostapedotomy, hearings were improved and mean postoperative ABG was 11.1+/-11.3 dB. In eight patients (66.7%), ABG was reduced to 20 dB or less. There was no intraoperative or postoperative complication except for mild postoperative vertigo for 1 or 2 days. CONCLUSION: Malleostapedotomy can be a safe and effective surgical procedure as an alternative of incus stapedotomy in certain cases of absence or anomalous incus long process, and/or immobile incus in patients with stapes fixation.
