Product Information

HIGH-PRECISION PATENTED SYSTEM

The TTP-VARIAC System provides variability that is unique throughout the world: It is comprised of two adjustable-length titanium prostheses (one Partial, one Total) and the multifunctional ACsizer Disk. With the aid of different sizes of Sizer attached to the latter the surgeon can determine the required length of prosthesis with precision.

On account of the patented clamping mechanism directly within the head plate the implant can be shortened to a Functional Length of up to 0.75 mm and the head plate can be securely fixed to the stem.

Developed in close collaboration with Tuebingen University ENT Clinic, Germany.

GOOD TO KNOW

The tension-sensitive annular ligament of the stapes footplate plays a key role in reconstruction of the ossicular chain: If undesirable pretension develops here, it can have a critical effect on postoperative hearing outcome. Short prosthetic solutions as short as 0.75 mm Functional Length are available to minimize risk of unintentional tension.
