Partial and total ceramic prostheses of the chain of ossicles incl. interponates of the incus and stapes were used in 22 operated ears. After a on-year interval following surgery in all instances the auditory threshold was either preserved or in the majority it improved. The best results were achieved, as expected, in posttraumatic damage of the chain of ossicles and in congenital dysplasia of the chain of ossicles. The results of ossiculoplastic operations using ceramic prostheses type PORP and TORP in chronic otitis media proved also hopeful.
