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.'] Does hearing result after stapedotomy with a nitinol piston prosthesis?
