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. Results. 8 of 9 Nitinol pistons were described as circular, and 3 of 9 manual crimped pistons were described as circular (P 66% of the incus and 3 of 9 to be in contact with 34–66% of the incus. 3 of 9 manually crimped pistons were considered to be in contact with >66% of the incus, 3 with 34–66% contact and 3 with less than 34% contact. Conclusions. The Nitinol “smart” stapes pistons were considered to provide a more circular and circumferential crimping and to have greater contact with the long process of the incus than conventional stapes pistons.

In this study, we visually compare the “smart” self-crimping shape memory Nitinol stapes prosthesis to the traditional manual crimping stapes pistons in temporal bone cadaver specimens. This may help determine if the Nitinol shape-memory stapes prosthesis will provide a more concentric crimp around the incus than manually crimped stapes prosthesis.

Using temporal bone cadaver specimens from the Madigan Army Medical Center temporal bone bank, 10 left and 10 right temporal bone specimens were randomly selected. All specimens had previously had a mastoidectomy with facial recess preformed. All specimens then underwent stapedectomy as described below. A traditional titanium manual-crimping piston was placed in 5 left and 5 right temporal bone specimens. A Nitinol shape-memory stapes prosthesis was placed in 5 left and 5 right temporal bone specimens. All of the key portions of the procedure were performed by senior author JVC in the ENT temporal bone lab equipped with a standard McGee stapes crimper, a microdrill and KTP laser.
