The CT Diagnosis and Clinical Information of Chronic Sinusitis

目的 :进一步提高对慢性鼻副窦炎CT征象的认识。材料和方法 :回顾分析 14 8例慢性鼻副窦炎的CT和临床资料 ,对照手术和病理发现分析其CT表现特征。全部病例均行冠状扫描 ,2 3例加作横断扫描 ,层厚5mm。对疑有窦壁骨质破坏的 5例加作HRCT。结果 :CT上 ,发现窦腔内软组织影充填者 2 9例 ,手术和病理证实其中为潴留囊肿 19例 (上颌窦 18例 ,蝶窦 1例 ) ,息肉 8例 (上颌窦 ) ,筛窦粘液囊肿 2例。上颌窦内钙化 11例 ,其中见于霉菌感染者 9例。CT误诊上颌窦坏死性息肉为肿瘤者 1例。结论 :CT能清楚显示慢性鼻副窦炎的范围 ,程度和某些致病原因 ,对手术治疗方案的制定有重要指导作用。

Objective： To improve the realization of image m chronic sinusitis. Materials and Methods： CT and clinical informations were analysed retroslwctly in 148 cases, and the operative results and pathologic reports were compared with CT the characteristics from scanning. All eases undenvent coronal position scanning, 23 cases underwent transverse position scanning too with 5mm slice and 5 cases underwent HRCT scanning. Result： Twenty- nine cases were found that paranasal sinuses had filling with soft tissue, in which 19 cases were cystic, 8 cases were polypoid; paranasal sinuses found calcification in 11 eases, in which 9 cases fungus infection. One patient was not diagnosed, but it was thought to be a tumor. Conclutions： CT scan could show clearly the range, degree and nosogenesis of chronic sinusitis, it had rely importance founction in establishment therapy regimen.
