OBJECTIVETo review hearing results after implantation of a self‐crimping stapes prosthesis.STUDY DESIGN AND SETTINGAnalysis of hearing results in patients implanted with a self‐crimping stapes prosthesis at two academic hospitals from 2000 to 2004.RESULTSSeventy‐nine ears were divided into short‐term and intermediate follow‐up groups. The mean postoperative air‐bone gap (ABG), preoperative minus postoperative ABG, and preoperative minus postoperative bone conduction values were 5.7, 21.4, and 4.1 dB, respectively, for the short‐term group, and 6.3, 22.3, and 4.7dB, respectively, for the intermediate group. The ABG was <10 dB in 88 percent of the short‐term group and in 79 percent of the intermediate group.CONCLUSIONSThe self‐crimping Nitinol stapes prosthesis provides excellent short‐term and intermediate postoperative hearing results, and may overcome the limitations of stapes prostheses requiring manual crimping.SIGNIFICANCEThis paper provides evidence for the use of a self‐crimping Nitinol stapes prosthesis, which may simplify hearing restoration surgery for stapes fixation.
