[Incus homograft--histological study of implanted ossicles (author's transl)].

The methodes of obtaining, preparing and storing of ossicles for homoiotransplantation is described. Using this method, 21 patients have been operated. Four reoperations have been performed, and in two cases implants were found and subsequently subjected to histological analysis. The method of preparing the histological slides is described. The study of examined homografts revealed the normal bone structure and signs of revitalisation, which is clearly shown in the micrographs. On the basis of functional results and histological examination, the authors conclude that the use of devitalised homografts is recommanded in total and/or partial defects of ossicles.
