  Armstrong-Style Pistons
Platinum/Plasti-PoreTM Material.
Plasti-PoreTM material shaft invites ingrowth for stabilizing the prosthesis in the oval window niche or on a tissue graft. The piston features an Armstrong-style platinum "ribbon" which resists "spring back", permiting proper forceps closure on the incus. Flat cross-section of the loop provides a wide area of contact to discourage point necrosis.

  McGee Pistons
Platinum/Stainless Steel
This improved version of the popular McGee Pistons features a platinum ribbon loop attached to a stainless steel piston. Platinum offers good tissue tolerance and is eassier to bend into shape. In its flattened form, it permits a greater area of surface contact with the incus, lessenging the opportunity for pressure necrosis. Each piston also includes a 0.5 mm depth groove to assist in visualization of footplate penetration. This groove is clearly visible at virtually aby angle. A choice of piston diameters is available.

  Richards Bucket Handle Prostheses
Titanium
A clinically proven piston design in a choice of well-tolerated material - titanium. The opening in the "bucket" of the prosthesis is modified to allow the incus to assume its corrected anatomical position minimizing the danger of pressure necrosis. The bucket handle fits easily over the lenticular process eliminating any need for crimping and the postoperative chances of presure necrosis. The Bucket Handle Prostheses fits either the left or right ear. A hole in the posterior bucket allows for pick insertion to aid in positioning. Two transaxial holes in the distal end of the prosthesis stern allow for tissue ingrowth to aid in the stabilization of the implant.

  Platinum Ribbons Loops
Platinum
Platinum is well-tolerated by tissue. It is exceptionally malleable, retaining its formed shape without "spring-back". Flattened band or "ribbon" permits a greater area contact point on the long process of the incus, lessening the possibility of point necrosis. There is also a wider contact point where the "ribbon" touches the incus.

Wide, flat base of the "trapeze" at the distal end of the loop provides greater contact area for improved position at the oval window. Flattened band or "ribbon" permits a greater area of contact point on the long process of the incus, lessening the possibility of point necrosis. There is also a wider contact point where the "ribbon" touches the graft.

  Richards Bucket Handle Prostheses
A clinically proven piston design in a choice of well-tolerated material - fluoroplastic. The opening of the "bucket" of the prosthesis is modified to allow the incus to assume its correct anatomical position minimizing the danger of pressure necrosis. The bucket handle fits easily over the lenticular process eliminating any need for crimping and the postoperative chances of pressure necrosis. The Bucket Handle Prosthesis fits either the left or right ear. A hole in the posterior bucket allows for pick insertion to aid positioning.

  Applebaum Incudostapedial Join Prostheses
Dense Hydroxilapatite
Restablishes the ossicular chain when the incudostapedial joint is missing. Eliminates the need for a bone chip interposition or removal of the incus.
Recommended Surgical Technique*:
1.
Elevate a tympanomeatal flap and established good exposure of the incudostapedial joint area. Palpate the incus and stapes to ensure their mobility.
2. Determine the appropiate size of the implant required by aproximating the size of the defect. The small prosthesis is generally suficient for most defects with the large prosthesis needed for bigger defects.
3.
Grasp the implant with alligator forceps and slide the through portion under the long process of the incus. Place the "hole" over the head of the stapes.
4.
Visulize the head of the stapes through the hole that runs through the prosthesis in order to assure proper positioning of the implant.
5.
The prosthesis is self-supporting if it is positioned properly. Palpate the malleus to verify good motion transmission the prosthesis to the stapes.

  Grote Incus-Stapes Prostheses
Hydroxilapatite
This Prosthesis is designed for use in case of a missing and stapes superstructure but a mobile footplate. Each implant is formed of dense hydroxylapatite, a highly biocompatible material with a chemical composicion nearly identical to bone. This material may rest directly against the tympanic membrane with minimal risk of extrusion.
To Use: Measure the distance from the footplate to the undersurface of the tympanic membrane and the offset between the centirline of the footplate and the handle of the malleus. Use the measurements to trim the prosthesis to the proper dimensions using a diamond burr and irrigation. From a pocket between the handle of the malleus and the tympanic membrane, place the top of the prosthesis in this pocket, and align the shaft into the footplate.
