  • Abstract
  • Look Inside

From December 1987 through December 1991, tympanoplasty using hydroxyapatite ossicular prosthesis was performed and postoperative follow-up for more than six months was con-ducted in 29 ears ; 15 ears with conductive hear-ing loss with intact tympanic membrane, 10 cholesteatoma and 4 chronic otitis media.

The analysis on these cases revealed that 89.7 % of the ears satisfied the criteria of success according to classification recommended by Otological Society of Japan.

All 15 ears with conductive hearing loss with intact tympanic membrane were judged as sucess according to this criteria, while in ears with cholesteatoma or chronic otitis media success rates were lower.
