In tympanoplasty, we always used cortical bone chips for reconstruction of the posterior bony external ear canal and for obliteration of the radical mastoid cavity. But if enough bone chips were not obtained, we used hydroxyapatite (Apaceram ®) plate for posterior ear canal reconstruction and hydroxyapatite (Apaceram®) granules for mastoid obliteration.
Hydroxyapatite plate and/or hydroxyapatite granules were used in 33 ears, between 1989 and 1996 with an average follow-up period of 44 months. These cases were 3.4% of 965 ears undergone tympanoplasty with posterior ear canal reconstruction and mastoid obliteration at the same period. We have no serious complication in these 33 ears.
It was concluded that tympanoplasty using hydroxyapatite with scrupulous care is safe and useful.
