| 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101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32．67％、板障型27．22％、硬化型23．76％、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79．21％、65．35％、41．58％和73．28％。听骨链、脑板和骨上棘骨质破坏分别为37．62％、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23．76％、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、对本病诊断及手术治疗有重要指导意义。 |
