AccessGUDID - CliP Partial Prosthesis Titanium (EHKM10022531)- Ossicular Prosthesis, partial The CliP Piston àWengen is a titanium stapes prosthesis with a CliP that standardizes the attachment to the incus. The prosthesis is coupled medially and laterally, therefore minimizing the risk of unintentional movements in the direction of the inner ear. This is particularly important during cases where more extensive eardrum reconstruction is required. The objective of the study was to determine whether a titanium piston stapes prosthesis would be audiometrically and surgically equivalent to a Robinson stainless steel piston for stapedectomy. Objective: Assess the safety of performing magnetic resonance imaging (MRI) on patients with stapes prostheses. Most of the prostheses were then placed in a water-filled Petri dish and reintroduced into the MRI unit. Setting: Private otology practice. 2007 Sep;28(6):733-8.
