The Kraus K-Helix Prosthesis (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.

  • Coil design permits universal adjustability in the OR
  • Can be used with or without cement
  • No crimping necessary
