Biocompatibility of nitinol stapes prosthesis.
OBJECTIVE Use of the SMart piston, a nitinol-based, self-crimping prosthesis in stapes surgery may allow improved functional results because of better sound transmission properties at the incus-prosthesis interface because of the elimination of manual crimping. Possible disadvantages include thermal damage or strangulation of the incus and its mucoperiosteum or nickel intolerance. The goal of t...

متن کاملThe Relationship between Stapes Prosthesis Length and Rate of Stapedectomy Success
OBJECTIVES To identify whether measurement of the prosthesis length is mandatory in patients requiring otosclerosis surgeries and to assess their postoperative audiometric outcomes. In addition, evaluation of prosthesis length used in revision compared to primary stapedectomy was carried out. STUDY DESIGN Case series with chart review. METHODS Chart review of 393 patients undergoing primary...
متن کاملNew chamber stapes prosthesis – A preliminary assessment of the functioning of the prototype
Piston-stapedotomy is the most common method for hearing restoration in patients with otosclerosis. In this study, we have experimentally examined a prototype of a new chamber stapes prosthesis. The prototype was implanted in a human cadaver temporal bone. The round window vibrations before and after implantation were measured for the acoustic signal (90 dB SPL, 0.8-8 kHz) in the external audit...
