The result allows sound waves to be sent once again to the inner ear for hearing. The surgeon performs the procedure through the ear canal and uses an operating microscope.

- Hammer (malleus) — attached to the eardrum.
- Anvil (incus) — in the middle of the chain of bones.

Are there any titanium middle ear prostheses in the US?
Methods A chart review was conducted including the postoperative results, complications, and audiometric data for 34 patients with titanium middle ear implants (21 Tuebingen VARIO prostheses [Kurz Co, DuBlingen, Germany] and 13 Micron Monolithic prostheses [Gyrus ENT, Bartlett, TN]) with an average follow-up of 19 months.
How is the head plate of a titanium prosthesis fixed?
On account of the patented clamping mechanism directly within the head plate the prosthesis can be shortened to a Functional Length of up to 0.75 mm and the head plate can be fixed to the stem securely. Developed in close collaboration with Tuebingen University ENT Clinic, Germany.
