Twenty five patients with severely damaged middle ears underwent reconstructive surgery with using total tympano-ossicular allografts. Two years long follow-up showed average air-bone gap about 20 dB or better in 44% of patients. Materials and methods used for reconstruction in two groups (part I and II) were compared, basing on anatomical and functional results. In patients with total perforation and lack of malleus, reconstruction with the tympanic membrane allograft attached to the malleus handle and shaped incus columella revealed long-term hearing results improvement (63.6% closure of air-bone gap within 20 dB) better than in similar patients with a total tympano-ossicular allograft (44% closure of the air-bone gap within 20 dB) during 2 years long follow-up.
25例中耳严重受损患者接受了使用全鼓室听骨异体移植物的重建手术。长达两年的随访显示，44%的患者气骨导间距平均约为20 dB或更小。根据解剖和功能结果，对两组（第一部分和第二部分）用于重建的材料和方法进行了比较。在鼓膜完全穿孔且锤骨缺失的患者中，将鼓膜异体移植物附着于锤骨柄并塑形为砧骨小柱进行重建，在长达两年的随访中，其长期听力结果改善情况（63.6%的患者气骨导间距在20 dB内闭合）优于使用全鼓室听骨异体移植物的类似患者（44%的患者气骨导间距在20 dB内闭合）。
