摘要
目的:探讨慢性中耳乳突炎HRCT特征及其诊断。方法:分析97耳慢性中耳乳突炎患者影像资料,与手术病理结果对照。结果:HRCT能清楚显示耳部正常影像解剖结构及其变异。97患耳HRCT诊断及分型和手术病理诊断基本吻合。结论:HRCT能准确的显示鼓室和/或乳突窦内软组织病灶的分布、形态及听小骨、鼓室壁及邻近重要结构的破坏情况,在慢性化脓性中耳炎诊断、分型及临床治疗方面有重要价值。
Objective： To evaluate the value of high resolution computed tomography （HRCT） in diagnosis of chronic suppurative otitis media. Methods ： Clinical data and HRCT findings collected from 97 ears with chronic suppurative otitis media were retrospectively studied in comparison with surgical pathological exams. Results ： Middle and internal auditory structures were clearly demonstrated on HRCT. Conclusion ： HRCT can precisely manifest the location and shape of the soft tissue mass in tympanum and/or mastoid antrum and the destruction of auditory ossicles, wall of tympanum and important structures in temporal bone. therefore, HRCT has great value in diagnosis of choronic suppurative otitis media and in its classification.
