目的:探讨颞骨螺旋CT在胆脂瘤型中耳炎诊断中的作用。方法:回顾性分析经手术及病理证实的104例胆脂瘤型中耳炎患者的CT资料,将手术结果与CT表现进行对比分析。结果:螺旋CT能清楚地显示起源部位不同和大小不等的胆脂瘤的软组织影充填征象及引起的中耳系统细微的骨质破坏征象。术前CT诊断骨壁受侵101耳,而术中发现为90耳,平均符合率为89.1%;术前CT显示胆脂瘤在中耳系统充填部位为108耳,与手术结果平均符合率为94.4%;术前CT诊断听骨链受侵为234耳,而术中证实为209耳,平均符合率为89.3%。结论:螺旋CT对胆脂瘤型中耳炎的诊断,尤其对判定骨质破坏的范围和软组织充填的部位,制定手术方案和评估治疗效果,具有重要的指导意义。
Objective: To investigate the role of temporal bone spiral CT in the diagnosis of cholesteatoma otitis media. Methods: CT data of 104 patients with cholesteatoma otitis media confirmed by surgery and pathology were retrospectively analyzed. The operative results and CT findings were compared. Results: Spiral CT can clearly show the signs of soft tissue filling of cholesteatoma with different origins and sizes, and the signs of subtle osteolysis of the middle ear system. Preoperative CT diagnosis of 101 cases of bone wall invasion, while the operation was found in 90 ears, the average coincidence rate was 89.1%; preoperative CT showed cholesteatoma in the middle ear filling site was 108 ears, and the results of the average coincidence rate was 94.4%; preoperative CT diagnosis of ossicular chain invasion was 234 ears, while the operation was confirmed as 209 ears, the average compliance rate was 89.3%. CONCLUSIONS: The diagnosis of cholesteatoma otitis media by spiral CT is of guiding significance in determining the scope of bone destruction, the site of soft tissue filling, the development of surgical plans and the evaluation of the therapeutic effect.
