目的 :探讨螺旋CT检查在慢性化脓性中耳炎诊治中的价值。方法 :研究 74例 93耳慢性化脓性中耳炎 ,比较术前CT所见与手术及病理结果。结果 :螺旋CT所见与手术结果基本相符 ,CT与病理分型符合率为 95 .7%。Ⅲ型慢性化脓性中耳炎听骨链及中耳骨壁破坏较Ⅱ型范围广且程度重。三维CT听骨链显示情况与手术一致。结论 :螺旋CT检查有助于慢性化脓性中耳炎的诊断和分型 ,三维CT成像对制定手术方案 ,提高手术安全性有很大潜力
Objective: To investigate the value of spiral CT in the diagnosis and treatment of chronic suppurative otitis media. Methods: Totally 74 cases of 93 cases of chronic otitis media with suppurative otitis media were studied. The findings of preoperative CT and surgical and pathological findings were compared. Results: The findings of spiral CT basically coincided with the surgical results. The coincidence rate of CT and pathological type was 95.7%. Type â ... ¢ chronic suppurative otitis media ossicular chain and destruction of the middle ear bone wall than a wide range of types and heavy. Three-dimensional CT ossicular chain shows the same situation with the surgery. Conclusion: Spiral CT examination is helpful for the diagnosis and classification of chronic suppurative otitis media. Three-dimensional CT imaging has great potential for developing surgical plans and improving surgical safety
