[摘要] 目的 探讨显微镜下鼓室成型与听骨链重建术在慢性化脓性中耳炎治疗中的应用效果，为临床治疗中耳炎提供参考。 方法 选取80例（80耳）慢性化脓性中耳炎手术患者分为治疗组与对照组各40例，对照组采用显微镜下鼓室成型方法，治疗组采用显微镜下听骨链重建术。 结果 两组患者四个频率（500 Hz、1 000 Hz、2 000 Hz、4 000 Hz）的骨导均值经过治疗后都有明显下降，但是治疗组的下降幅度更大，与对照组治疗后的值对比有明显差异（P < 0.05）。所有患者在术前后气骨导差均有明显下降。 治疗组较对照组在气骨导差缩小更加明显（P < 0.05）。 结论 相对于显微镜下鼓室成型方法，显微镜下听骨链重建术治疗慢性化脓性中耳炎能从多方面有效改善多听阈的听力状况，值得推广应用。

[Abstract] Objective To investigate the effects of attic molding and ossicular chain reconstruction for treating chronic suppurative otitis media in microscope for giving a reference for the clinical treatment of otitis media. Methods 80 patients (80 ears) with chronic otitis media were equally divided into the treatment group and the control group, each group had 40 cases. The treatment group was treated by ossicular chain reconstruction, and the control group was treated by attic molding. Results The average bone conduction in the four frequency (500 Hz, 1 000 Hz, 2 000 Hz, 4 000 Hz) of two groups were decreased signific...
