Method: Review and analyze the effect of ossicular chain reconstruct in 389 cases with chronic suppurative otitis media after surgery.
方法：回顾性分析389例慢性化脓性中耳炎患者的听骨链重建手术所见及术后效果。
Observation measures were bone conduction thresholds, changes of ossicular chain, preoperative and postoperative changes of pure-tone hearing.
观察术前骨气导阈值，听骨链改变，手术前后纯音听力改变。
Objective To investigate the hearing results of various materials in ossicular chain reconstruction, as well as those in open tympanoplasty and simple tympanoplasty.
目的探讨不同材料在听骨链重建术的应用效果和不同术式鼓室成形术后听力效果。
Purpose: to evaluate the imaging methods and display ability of spiral ct three dimensional (3d) reconstruction of auditory ossicular chain and its clinical application.
