We manufactured a new hydroxylapatite prosthesis "carti-lage connecting ossicular chain prosthesis" with a planar-like head portion to contact with a piece of cartilage. As a result, postoperative extrusion rate was 4/124 (3.2 %) which seemed lower than the conventional type, and hearing success rates were 78.8 % in modified type III tympanoplasty, 80.0 % in modified type IV tympanoplasty. Average improvement on air conduction were 13.5 dB in modified type III tympanoplasty, 17.5 dB in modified type IV tympanoplasty. Those good results were explained by that the "Cartilage connecting ossicular chain prosthesis" Was tightly attached with a reconstructed tympanic membrane and ossicular chain prosthesis might be stable in tympanic cavity.

抄録

　耳小骨の転位や排出などの問題点を解決するために,アパセラム人工耳小骨の頭部に軟骨を接合しうる軟骨接合型人工耳小骨を開発した。6カ月以上経過観察された皿型変法99耳,IV型変法25耳の計124耳について検討した。術後観察期間は平均16.6カ月で,耳小骨の排出をみたものは4/124耳(3.2%)であった。臨床耳科学会の聴力成績の判定と基準による成功率は皿型変法78.8%,IV型変法80.0%であり,特にIV型変法において従来の報告に比較し,優れた結果となった。
