The technique of reconstructing the posterior canal wall with homograft knee cartilage originally described in 1972 is reviewed and refinements are presented along with additional cases. The homograft knee cartilage is used in conjunction with the homograft tympanic membrane and ossicles to rebuild the middle ear and mastoid as near as possible to anatomical configuration and function. Anatomical follow-up of one year or more is reported on 63 ears. Satisfactory results were obtained in 36 of these ears or 57% of the total. Hearing results are reported overall and in relation to different types of reconstruction. One year or more follow-up demonstrates satisfactory hearing with an air-bone gap of 20 db or less in 77% of the postoperative ears.
回顾了1972年首次描述的同种异体膝关节软骨重建后鼓室壁技术，并介绍了改进方法及更多病例。同种异体膝关节软骨与同种异体鼓膜和听小骨联合使用，尽可能重建中耳和乳突的解剖结构和功能。报告了对63只耳朵进行的一年或更长时间的解剖学随访。其中36只耳朵（占总数的57%）获得了满意的结果。报告了总体听力结果以及与不同类型重建相关的听力结果。一年或更长时间的随访表明，77%的术后耳朵气骨导差为20分贝或更小，听力令人满意。
