Five-year hearing results with the shape memory nitinol stapes prosthesis.
OBJECTIVES/HYPOTHESIS To evaluate the long-term (5-year) results of the shape-memory nitinol stapes piston in the surgical treatment of otosclerosis. STUDY DESIGN Retrospective case review in a tertiary referral center. METHODS The patients were adults with clinically proven otosclerosis undergoing stapedotomy. Stapedotomy and ossicular chain reconstruction using a shape-memory nitinol stap...
متن کاملBiocompatibility 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 کاملComparison of the Effectiveness of teflon piston and titanium stapes prosthesis in hearing improvement
Background & objectives: The aim of this study was to compare the effectiveness of two stapes prostheses in hearing improvement of patients undergoing stapes surgery for otosclerosis. Materials & Methods: In this retrospective and descriptive study, the charts of 291 stapedectomies performed by one surgeon (first author) from 1997 to 2011 in Imam Khomeini and Apadana hospitals of Ahvaz were...
متن کاملEffect of Electrical Current on Nitinol Medical Staples Shape Memory
Medical staples are one of the nitinol shape memory alloys applications which their pedicles have to be bent for suitable function with an appropriate angle at a specified temperature .It is achievable by shape memory effect. For this purpose, samples of nitinol super elastic alloys were bent in a steel mold with different angles & formed orthopedic staples. Then shape memory effect was induced...
