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

Key words:
auditory gain, chronic otitis, disjunction of the chain of ossicles, conductive deafness,hydroxyapatite
