摘　　要：目的研究多层螺旋CT(MSCT)多平面重建对人工听骨链重建术疗效的评估价值。方法回顾性分析我院45例行人工听骨链重建术的患者临床资料,所有患者术后均进行MSCT检查,分析MSCT多平面重建对人工听骨链重建术疗效的评估价值。结果 MSCT多平面重建显示,45例患者中有35例人工听骨连接完好且未见中耳炎症;4例人工听骨连接完好,中耳有炎症但未累及听骨链;2例人工听骨连接完好,中耳有炎症且累及听骨链;2例可见听骨链和周围组织间发生钙化连接;2例人工听骨移位脱出。Spearman相关性分析显示,MSCT评分与临床疗效评价结果的等级相关系数r=-0.771,P<0.05,相关性显著。MSCT诊断灵敏度、特异度、准确度分别为85.71%、100%、97.78%。结论 MSCT多平面重建可清晰显示人工听骨位置和形态以及周围组织结构关系,对人工听骨链重建术疗效评价具有重要指示作用。Objective To study the evaluated value of multi-slice spiral CT(MSCT) multiplanar reconstruction on the efficacy of artificial ossicular chain reconstruction. Methods The clinical data of 45 patients undergoing artificial ossicular chain reconstruction in our hospital were analyzed retrospectively. All patients were given MSCT examination. The evaluated value of MSCT multiplanar reconstruction on the efficacy of artificial ossicular chain reconstruction was analyzed. Results MSCT multiplanar reconstruction showed that among 45 patients, there were 35 cases of intact ossicular connection and no otitis media, 4 cases of intact ossicular connection and otitis media but no involvement of ossicular chain, 2 cases of intact ossicular connection, otitis media and the ossicular chain involvement, 2 cases of calcification connection between ossicular chain and surrounding tissue and 2 cases of artificial ossicular displacement and prolapse. Spearman correlation analysis showed that the correlation coefficient between MSCT score and clinical efficacy evaluation results was r=-0.771, P<0.05, and the correlation was significant. The sensitivity, specificity and accuracy of MSCT diagnosis were 85.71%, 100% and 97.78%, respectively. Conclusion MSCT multiplanar reconstruction can clearly show the position and shape of artificial ossicular bone and structure of surrounding tissues, and has an important indication for the evaluation of efficacy of artificial ossicular chain reconstruction.
