The Kraus K-Helix Prosthesis (endohelix prostheses) is a novel, titanium middle ear prostheses that has been designed specifically for reconstruction of the ossicular chain. When used with middle ear cements, such as glass ionomer cement, endoskeletal ossicular reconstruction is possible. The prosthesis serves as “rebar” for the cement. The unique design permits the prostheses to be adjusted by expanding the coils to increase length or by removing extra coils to make it shorter. The piston may be used with a mobile or immobile footplate. A footplate shoe is available when used with a mobile footplate.
