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 کاملComparison of Nitinol Stapes Pistons with Conventional Stapes Pistons: A Cadaver Study
Objective. To visually compare the Nitinol "smart" stapes prosthesis to conventional manual crimping stapes pistons in temporal bone cadaver specimens. Main Outcome Measures. 10 otolaryngologists were given a photograph of the randomly ordered stapes pistons and asked to use the pictures to answer questions about each stapes piston. The answers to the survey were then recorded for analysis. Res...

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 کاملMalleostapedotomy with a self-crimping superelastic nitinol prosthesis.
INTRODUCTION One of the most difficult and time-consuming steps in malleostapedotomy surgery is the crimping of the prosthesis onto the malleus handle manually. The advent of the nitinol prosthesis (Gyrus nitinol piston [GNP]; Gyrus ENT LLC, Bartlett, TN) significantly reduced the difficulty of this surgical step, rendering its fixation to the malleus easy and fast. However, Kwok et al. analyze...
