Chronic otitis media is frequently seen in otolaryngologic practice. Cholesteatoma is less common and can present a diagnostic challenge. Temporal bone imaging studies are often used both to support the clinical diagnosis of cholesteatoma and to ascertain the extent of the disease. The exact role of CT in patients with cholesteatoma is unclear. This retrospective study compares CT with the operative findings in 44 patients operated on for cholesteatoma. Results show that while CT can detect abnormalities in the temporal bone, its ability to diagnose cholesteatoma is poor. We conclude that CT should be used selectively in those patients presenting diagnostic dilemmas or when other concomitant pathology (i.e., complications, recurrent disease, etc.) is suspected.
慢性中耳炎在耳鼻喉科临床实践中很常见。胆脂瘤则较为少见，且可能带来诊断挑战。颞骨影像学检查常被用于支持胆脂瘤的临床诊断并确定疾病范围。CT在胆脂瘤患者中的确切作用尚不清楚。这项回顾性研究比较了44例接受胆脂瘤手术患者的CT检查结果与手术发现。结果显示，虽然CT能够检测出颞骨的异常情况，但其诊断胆脂瘤的能力较差。我们得出结论，对于那些存在诊断难题或怀疑有其他伴随病变（如并发症、复发性疾病等）的患者，应选择性地使用CT。
