Abstract

To compare the hearing results in patients with otosclerosis who underwent a stapedotomy with either a platinum wire prosthesis or a commercially available, heat-activated nitinol stapes piston prosthesis. Retrospective medical chart review. Academic tertiary care medical center. Seventy-nine consecutive patients diagnosed as having otosclerosis who underwent primary stapedotomy (33 men and 46 women) were included in this study (41 ears per group). Stapedotomy. The operative records of the senior surgeon (B.J.G.) were retrospectively reviewed, and hearing results were obtained. The hearing results of the patients who received a platinum wire prosthesis were compared with those who received a nitinol prosthesis. Results for the platinum wire prosthesis group revealed a postoperative mean (SD) air-bone gap (ABG) of 7 (6) dB, a mean (SD) ABG closure of 21 (12) dB, and a postoperative mean (SD) speech reception threshold of 25 (16) dB. Results for the nitinol prosthesis group revealed a postoperative ABG of 8 (6) dB, an ABG closure of 25 (10) dB, and a postoperative speech reception threshold of 25 (12) dB. These data show that the nitinol prosthesis is equivalent to the platinum wire prosthesis in closing the ABG in patients with otosclerosis. Comparable efficacy combined with the ease and safety of heat-activated crimping supports the continued use of this prosthesis for stapes surgery.
