Total implant made of titanium, for reconstructing a destroyed middle-air ossicular chain (chain of sound transmission) between the footplate of the stirrup bone and the plane of the eardrum. The implants are available in fixed length and adjustable versions for shortening. The implant can be subdivided into three areas: 1.) the implant shoe; 2.) the implant shaft; 3.) the perforated implant plate. The implant plate can be arranged centrically (round) towards the implant shaft or eccentrically (oval). In the eccentric version (oval, fixed length only), an additional groove has been worked into the plate to improve receiving the malleus handle. The surface of the predefined contact points (upper side of implant plate and implant shoe) is roughened in order to facilitate better bonding to the eardrum resp. the stapes footplate. To improve the adaptation of the implant plate to the plane of the eardrum, the angle between the implant plate and shaft can be optimally adapted because the shaft below the implant plate tapers off (onwards from a total length of 3.5 mm). The product is available in different lengths. The length information is stated both on the outer package as well as on the product’s sterile packaging.
