Middle ear reconstruction using the titanium Kurz Variac partial ossicular replacement prosthesis: functional results The Classic Bucket Handle Prosthesis is constructed out of titanium with a patented micron finish, which not only smoothes the surface to reduce the potential for extrusion due to sharp angles, but it also dulls the surface to reduce glare. All titanium implants are MRI compatible. AccessGUDID - MNP Total Prosthesis Titanium (EHKM10044381)- Ossicular Prosthesis, total Methods: A survey regarding implant usage, MRI procedures, and adverse outcomes after MRI in patients previously undergoing stapes procedures. Prosthesis materials. The aim of reconstructing the ossicular chain is to create the natural function as closely as possible and conduct the incoming acoustic signal to the inner ear with minimal loss. When applying heat to the ContactFree Zones, the shape memory features of Nitinol cause the loop to close. We call this our most challenging quality control and use it as an incentive to prove to ourselves that we can live up to the standards of our best critics. 3 Cobalt chrome is the most common type of knee implant, though titanium is available for people with a nickel allergy. The efficiency of titanium middle ear prosthesis for ossicular reconstruction in chronic ear disease is investigated in a Scandinavian two-center retrospective study from a Norwegian tertiary otology referral center and a Finnish otology referral center. Conclusion and Relevance: The titanium Kurz TTP-Variac System PORP is an effective prosthesis to reconstruct the ossicular chain. Especially in the case of extensive eardrum reconstructions this stability is a major advantage. In ossicular chain reconstruction, maximal rehabilitation of conductive hearing loss is the ultimate goal.

The focus of our review is to demonstrate the value of the two-point stabilization in total ossiculoplasty. All titanium implants are MRI compatible. Included in this study was a Kurz partial titanium prosthesis, which was found to have a low but present magnetic dipole moment. The manufacturing process of our prostheses requires highest precision and quality standards as well as utmost care. Meulemans J., Wuyts F. L., Forton G. E. J. It is often safe to perform MRI on an individual that has an orthopaedic implant device. The stapes prosthesis consists of a Nitinol loop and the standard KURZ shaft made of pure titanium (ASTM F67). The CliP Piston àWengen is a titanium stapes prosthesis with a CliP that standardizes the attachment to the incus. Otolarngol Clin … Middle ear reconstruction using the titanium Kurz Variac partial ossicular replacement prosthesis: functional results KURZ once again pioneered this kind of safety feature and for over a decade it has remained the market leader. Common materials used to make the prostheses are platinum, a combination of platinum and PTFE and, increasingly, titanium. This is particularly important during cases where more extensive eardrum reconstruction is required. The titanium Kurz TTP-Variac System PORP is an effective prosthesis to reconstruct the ossicular chain. There were few complications (1 prosthesis extrusion, 2 prosthesis dislocations, 2 reperforations, 3 cases of residual cholesteatoma, and 3 of light sensorineural hearing loss). The superiority of these new implants compared to previous middle ear prostheses with respect to biocompatibility, hearing improvement and intraoperative manipulation became evident even in the testing phase. adverse tissue effects attributable to MRI-generated heating.
