目的：观察用人工钛质听骨重建听骨链的疗效。方法：用钛质听骨重建听骨链６０例、６５耳，并随访１０～２４月。结果：听力提高＞１０ｄＢ ＨＬ者５８耳（８９．２％），气骨导闭合＜２０ｄＢ ＨＬ者３７耳（５６．９％），听力达应用水平４５耳（６９．２％）。结论：听骨链重建应用人工钛质听骨，生物相容性和组织亲合性好，无毒性，耐腐蚀，重量轻，与镫骨连接牢固，不易脱位，术后听力提高幅度大，疗效显著。
Objective: To observe the curative effect of reconstruction of ossicular chain with artificial titanium. Methods: Sixty cases (65 ears) of ossicular chain were reconstructed with titanium, followed by 10-24 months. Results: 58 ears (89.2%) with hearing improvement> 10dB HL and 37 ears (56.9%) with <20dB HL were closed and 45 ears (69.2%) had hearing level. Conclusion: The artificial bone of ossicular chain reconstruction with good biocompatibility and tissue affinity, non-toxic, corrosion-resistant, light weight, strong connection with tarsal bone, difficult to dislocation, large increase of hearing after operation Significant.
