[Homograft of incus in tympanoplasty]

Homograft of incus was applied for reconstruction of the ossicular chain in 34 patients. Two basic variations of plastics have been performed. The handle of malleus was supported by the body of the incus with the drilled hole, while the long process of the incus, after a little shortening, was put on the movable footplate of stapes. In the second variation the long process of the incus was amputated--here the drill hole was performed for the head of stapes and the second one in the body of the incus for the handle of malleus. In the average three years after the operation the good hearing results were achieved in 19 (55.9%) patients. From this group in 8 (23.5%) patients aerbone gap closure was at the level of 10 dB. The bad morphologic results was ascertained in 3 patients.
