CT扫描在副鼻窦疾病诊断中的应用

目的评价CT扫描在副鼻窦疾病诊断中的应用价值。方法对271例患者行副鼻窦轴扫和冠扫，分析副鼻窦疾病病变的类型、范围。结果单纯上颌窦炎62例，单纯筛窦炎16例，单纯蝶窦炎1例，单纯额窦炎0例，上颌窦＋筛窦47例，上颌窦＋蝶窦2例，上颌窦＋额窦3例，筛窦＋蝶窦2例，上颌窦＋筛窦＋蝶窦17例，上颌窦＋筛窦＋额窦24例，上颌窦＋筛窦＋蝶窦＋额窦32例，上颌窦囊肿15例，鼻甲肥大、鼻炎80例，鼻中隔偏曲7例，息肉30例。结论副鼻窦CT扫描能准确显示副鼻窦病变的类型、范围。清晰显示副鼻窦的解剖和毗邻关系。

The application of CT scan for paranasal sinus diseases diagnosis

Objective To evaluate the application value of CT scan for paranasal sinus diseases diagnosis. Methods Axial and coronal scan the paranasal sinus for 271 patients,to analyze the types and areas of paranasal sinus diseases. Results The simple maxillary sinusitis in 62,the simple ethmoid sinusitis in 16, the simple sphenoid sinusitis in 1 ,no simple frontal sinusitis was found, maxillary sinusitis and ethmoid sinusitis in 47,maxillary sinusitis and sphenoid sinusitis in 2,maxillary sinusitis and frontal sinusitis in 3,ethmoid sinusitis and sphenoid sinusitis in 2, maxillary sinusitis,ethmoid sinusitis and sphenoid sinusitis in 17, maxillary sinusitis,ethmoid sinusitis and frontal sinusitis in 24, maxillary sinusitis, ethaoid sinusitis, sphenoid sinusitis and frontal sinusitis in 32,maxillary cyst in 15,nosepiece hypertrophy and rhinitis in 80, dedviation of nasal sptum in 7, rhinopolypus in 30. Conclusion CT scan can disptay the types and areas of paranasal sinus diseases accurately,and show the anatomy and abut of paranasal sinus clearly.
