OBJECTIVE: Crimping of the stapes prosthesis might result in injury to the incus. Attachment is often not tight. Facilitated fixation of a stapes prosthesis could improve surgery and provide more stable results. MATERIALS AND METHODS: After the development of a unique titanium clip over a 6-year period (Kurz AG, Dusslingen, Germany) and reception of a CE mark, the first implantation was performed in September 2000. Full FDA approval was received in June 2002. RESULTS: Only 60% of the circumference of the incus is touched by the clip permitting adequate mucosal blood supply to the lenticular process. Application of the prosthesis is quick and stable. DISCUSSION: This new stapes prosthesis facilitates surgery and reduces operation time. There is no need for crimping anymore. Acoustic coupling is ideal due to the spring action of the self-retaining clip. Most surgeons have switched entirely to this prosthesis. Long-term results will be needed to prove the reduction of incus necrosis.
