title: [Formation of new bone and bone destruction in preserved incus homografts. Histological examinations of implants from 100 patients (author's transl)].
abstract: 103 tympanoplastic re-operations were done in 100 patients. 103 Cialit-preserved incus homografts were drawn out for histological examination, which were implanted in the mean two years before. The data of the course of the disease were correlated with the histological finding. All incus homografts showed the well known formation of new bone in a different amount. Moreover 50% showed already macroscopically signs of bone resorption. Distinct indications for defense reactions of the recipient against the devital incus homograft were detected.
