摘　　要：目的分析慢性化脓性中耳炎合并静脉窦血栓的多排螺旋CT(multiplana spiral CT,MSCT)和磁共振成像(magnetic resonance imaging,MRI)表现,比较MSCT和MRI的临床应用价值。方法对比分析5例经手术、病理证实的慢性化脓性中耳炎合并静脉窦血栓的MSCT和MRI特征。结果MSCT可清晰显示鼓室及鼓窦内软组织密度影和听小骨破坏;增强扫描能清晰显示乙状窦血栓及其范围,其中2例血栓累及颈内静脉,且均有颈静脉球高位。MRI不能显示岩骨细微的骨质结构,但可以显示中耳炎性病变的范围和性质;增强MRI扫描可以显示静脉窦内血栓,但对血管与血栓的细节显示不如MSCT。结论慢性化脓性中耳炎合并静脉窦血栓,增强MSCT可为首选的无创性检查方法。Objective To analyze the multiplanar spiral computerized tomography（MSCT） and magnetic resonance imaging （MRI） characteristics of chronic suppurative otitis media complicated with venous sinuses thrombosis and to compare the clinical role between MSCT and MRI. Methods The MSCT and MRI images of 5 patients diagnosed as chronic suppurative otitis media complicated with venous sinuses thrombosis were analyzed retrospectively. Results MSCT could identify the soft tissue plaques and the erosion of auditory ossicle in the tympanic cavity and tympanic sinus. The range of sigmoid sinus thrombosis could be shown clearly by enhancement scanning with 2 cases identified as internal jugular vein thrombosis superior-positioned. MRI could show the range and nature of the pathological changes in auris media, but not the fine sclerotic structure of os petrosum. Enhancement MRI scanning could show the thromb in sinus venous, but no better than MSCT in showing the circumstance of vein and thromb. Conclusions MSCT is a better non-invasive technique in the diagnosis of chronic otitis media suppurativa complicated with venous sinuses thrombosis.
