Swartout, B, Wazen, JJ. Laser-Activated Crimping of Nickel and Titanium Alloy Piston Stapes

Laser-Activated Crimping of Nickel and Titanium Alloy Piston Stapes

Benjamin Swartout, MD (presenter); Jack J Wazen, MD. New York, NY.

Problem: To determine the safety and effectiveness of the nickel and titanium alloy wire-piston stapes prosthesis crimped using the laser activation technique.

Methods: A retrospective analysis of all stapes procedures performed by the senior author over a 3-year period was reviewed with special attention directed at those cases performed using the laser activated crimping technique. All patients were followed for at least 6 months. The surgical outcome including audiologic data and complications are noted. Stapes surgery was performed on an ambulatory basis by way of a transcanal approach under general anesthesia. The implant made from a nickel and titanium alloy was inserted into the middle ear in the “open” position. After
proper positioning, a laser was directed at the alloy causing the implant to close to a predetermined shape, thereby attaching itself firmly to the incus bone in the middle ear.

Results: There was no significant difference in the airbone gap closure or complication rate between the laser assisted crimping technique and the standard technique.

Conclusion: Stapes surgery using the nickel and titanium alloy wire piston prosthesis crimped with a laser activation technique is safe and effective.

Significance: This study describes a technique that may allow surgeons to perform stapes surgery more rapidly and easily.
