摘要
目的:通过高分辨率CT(HRCT)分析中耳鼓室窦深位的发生率,为耳科临床工作提供依据。方法:回顾分析300例(560耳)颞骨的HRCT轴位像,根据诊断结果将其分为正常组与疾病组,正常组158例(316耳),疾病组142例(244耳),统计鼓室窦深位的发生率,并对统计结果进行统计学分析。结果:300例(560耳)颞骨中鼓室窦深位的发生率为2.7%,该变异在两侧及性别间不存在差异。结论:HRCT可以准确显示颞骨的解剖变异,对临床及科研工作有重要价值。
Objective： To analysis the incidence of large sinus tympani and provide valuable reference for clinical otology by HRCT, Methods： 300 cases（560ears） of temporal CT axial images which were divided into two groups were retrospectively analyzed by statistics methods. There were 158cases （316ears） in normal group and 142cases（244ears） in abnormal group. The incidence of large sinus tympani were recorded. Results： Of all the 300cases（560ears）, the incidence of large sinus tympani was 2.7%, there were no significant differences among the incidence rates of large sinus tympani between two sides and genders. Conclusion： HRCT can show anatomic variances of temporal bone accurately and has great clinical value for clinical works and scientific researches.
