摘　　要：应用羟基磷灰石（ＨＡ）陶瓷人工听骨对不同类型的中耳疾病患者（含８２耳）施行了听骨链重建术。其中应用全听骨链赝复物（ＴＯＲＰ）者２５耳，部分听骨链赝复物（ＰＯＲＰ）者５７耳。术后随访６～４８月，７７耳术后听力有不同程度的改善，提高最少１０ｄＢ，最多达３５ｄＢ，ＰＯＲＰ听力平均提高２１．９ｄＢ，ＴＯＲＰ１８．４ｄＢ。故认为ＨＡ是人工听骨链的理想材料。对ＨＡ的生物学特性、术后听力改善情况及术中、术后有关注意事项也进行了讨论。By using hydroxyapatitic(HA) ossicle,tympanoplasty was performed on 82 ears with middle ear diseases.The post-operative follow-up period ranged from 6 months to 48 months.It was found that the hearing level of 77 ears have been improved from 10 dB to 35 dB.We believe that HA is a reliable material for making ossicle.The biological characteristics of HA and experience in post-operative cares were also discussed.
