【摘要】 目的探讨孤立性蝶窦炎的CT临床征象及诊断价值。方法回顾性分析我院1998年～2006年6月诊治的18例孤立性蝶窦炎的临床和影像学资料。全部患者均行蝶窦冠状位及水平位薄层CT扫描。结果本组中17例以头痛为主诉就诊。18例中,蝶窦气化分型为鞍前型7例(7/18,38.9%),鞍后型6例(6/18,33.3%),甲介型5例(5/18,27.8%)。12例蝶窦有中隔,其中1个中隔6例,2个中隔4例,2个以上中隔者2例;6例蝶窦为单房。CT表现为蝶窦腔的部分或全部混浊变暗,蝶窦内密度增高。11例行鼻内窥镜蝶窦开放冲洗术,7例行抗感染治疗,均治愈。结论CT可提供蝶窦解剖的细节和病变的范围,对鼻内窥镜手术有指导意义。CT可作为诊断孤立性蝶窦炎的首选方法。更多还原

【Abstract】 Objective To probe manifestations of isolated sphenoid sinusitis on CT as well as their usefulness for diagnosis. Methods Clinical and image data of 18 patients with isolated sphenoid sinusitis were reviewed. They were admitted by our hospital during June 1998-June 2006. All the patients underwent thin-layer coronal and axial CT scanning. Results 17 patients attended the hospital complaining headache. Among the 18 patients, 7 patients were antesellar (38.9%), 6 were postsellar (33.3%) and shell type (27.8%). 12 patients had septum, among them, 6 patients had 1, 4 patients had 2, 2 patients had more than 2, and 6 patients had single-chamber sphenoid sinus. Sinusitis on CT showed part or complete turbidity or darkness, and increased density in the sinus. 11 patients underwent in-nose-endoscope opening and rinsing, and 7 patients underwent antibiotic therapy. All patients were cured. Conclusion CT scanning is able to show detailed anatomy of the sinusitis lesions providing guidance to plan in- nose-endoscope operation.更多还原
