摘要
目的 评价颞骨CT影像对慢性中耳乳突炎诊治的临床意义。方法 通过对 10 1例慢性中耳乳突炎患者颞骨CT影像资料观察分析 ,包括乳突分型、病灶改变和解剖变异等影像资料进行统计。结果 乳突气化型 32 .6 7%、板障型 2 7.2 2 %、硬化型 2 3.76 %、混合型 13.37%、乳突术后 2 .97%。鼓窦、上鼓室、中鼓室及乳突低密度影出现率分别为 79.2 1%、6 5 .35 %、41.5 8%和 73.2 8%。听骨链、脑板和耳上棘骨质破坏分别为 37.6 2 %、3.96 %、16 .83 %。颈静脉球高位、乙状窦壁前移、乙状窦壁表浅和脑板低位发生率分别为 2 3 .76 %、14.85 %、1.98%、5 .94%。结论 颞骨冠状和轴位CT从不同角度显示中耳乳突的病理改变、解剖变异 。
Objective To understand the manifestation of the temporal bone in CT in chronic otitis media and to eva luate its clinical significance.Methods 101 COM cases were taken the coronal and axial CT and their images were analyzed as to observe their mastoidal type, focus of infection and anatomical abnormality.Results There were 32.67% pneumatic type,27.22% diploetic type,23.76% sclerosing mastoid and 13.37% mixed type.The destruction of ossicle chains,tegmenta and auricular supraspur were 37.62%,3.96% and 16.83% respectively.The high post of bulb of jugular,the antelocation and the superficial location of sigmoid sinus and low tegmenta were 23.76%,14.85%,1.98% and 5.94% respectively.Conclusion The temporal bone CT can show the focus of infection and anatomical abnormality from different angles. It plays very important signification in the diagnosis and tympanoplasty.
