胆脂瘤型中耳炎的螺旋CT应用

目的:分析胆脂瘸型中耳炎的螺旋CT表现,探讨螺旋CT在临床的应用价值。方法:经手术病理证实胆脂瘤型中耳炎48例,回顾性分析其螺旋CT表现,并与手术结果对照分析。结果:胆脂瘤型中耳炎的螺旋CT表现为鼓室、鼓窦及乳突区软组织肿块,常伴有骨质破坏,其中包括听小骨、盾板、面神经管、半规管、乙状窦及鼓室盖骨质破坏。结论:螺旋CT对胆脂瘤型中耳炎的准确诊断具有很高的价值,对指导临床治疗有重要意义。

Spiral CT Application of Cholesteatomtous Tympanitis

Objective To analyse the appearance of cholesteatomtous tympanitis on Spiral CT and clinical application. Methods Spiral CT findings of 48 patients with cholesteatomtous tympanitis proved bysurgery and pathology were analysed. Results Spiral CT findings of cholesteatomteus tympanitis included:soft tissue mass in the tympanium,tympanal sinus and mastoid,destruction of the bone including ossicles chain,secutum,facial nerve canal,semricirular canal,sigmoid sinus plate, tegmenttympanic.Conclusion Spiral CT is extremely accurate in diagnosis of cholesteatomtous tympanitis,and has significant value for directing clinic treatment.
