Huettenbrink KB, Beutner D (2005) A new crimping device for stapedectomy prostheses. Conclusionīased on the patient collective, stapes plasty using a Nitinol Superelastic stapes prosthesis is a sufficient method for improving the hearing conduction. There were no surgical complications in both groups. Moreover, the post surgery delta–bone-conduction pre- to post surgery showed no differences (0.5–6 kHz). In the Platin–Teflon group, the average of postoperative air–bone-gap was 14.9 dB. The Nitinol-group presented an average of postoperative air–bone-gap over all frequencies (0.5–6 kHz) of all patients of 15.1 dB. All operations were performed by the same experienced ear surgeon. In a retrospecitve setting, the audiological results of nine patients who have been implanted with a Nitinol Alloy Superelastic stapes prothesis were compared with the results of ten patients, which have been implanted with a Platinum–Teflon piston prostesis. The aim of the study was to evaluate the audiological results of the Nitinol Superelastic stapes prosthesis compared with a Platin–Teflon prosthesis. By reinforcing the prostheses, an optimization of the prosthesis could be achieved. Stapes plasty is an established procedure to improve hearing in case of otosclerosis.
