螺旋 CT 在鼻腔副鼻窦疾病诊断中的应用

Application of spiral CT in diagnosis of diseases of nasal cavity and paranasal sinusitis

目的探讨螺旋CT在鼻腔副鼻窦疾病诊断中的应用。方法收集156例经临床确诊的鼻炎、副鼻窦炎及鼻息肉患者的CT影像学资料,重点观察鼻腔鼻窦炎的CT表现和鼻腔鼻窦的解剖变异。结果鼻腔鼻窦炎性病变分为5型:漏斗型,占30.8%;窦口鼻道复合体型,占24.4%;蝶筛隐窝型,占9.0%;息肉型,占14.1%;其余为混合型,占21.8%。结论鼻腔鼻窦CT示各型鼻腔和鼻窦炎性病变与窦口鼻道复合体变异或蝶筛隐窝炎症、鼻甲气房、鼻中隔偏曲等解剖变异有相关性,为鼻内镜手术治疗提供重要的指导价值。

Objective To investigate the application of spiral CT in diagnosis of diseases of nasal cavity and paranasal sinusitis.Methods CT imaging data of 156 cases of clinically confirmed rhinitis,paranasal sinusitis and nasal polyp were collected to observe CT manifestation of sinonasal inflammation and anatomic variation of nasal cavity and sinus. Results Sinonasal inflammatory lesions was classified into 5 types：infundibular accounted for 30.8%;ostiomeatal com- plex accounted for 24.4%;sphenoethmoidal recess accounted for 9.0%;polyp accounted for 14.1%;mixing accounted for 21.8%.Conclusion Sinonasal CT scanning indicates correlation between sinonasal inflammatory lesions and anatomical variations,including ostiomeatal complex variation,sphenoethmoidal recess inflammation,turbinate air cell and deviation of nasal septum,providing valuable guidance for nasal endoscopic surgical therapy.
