【摘要】 目的进一步探讨缩鼻黏膜药物在慢性鼻炎鼻窦炎性病变CT诊断中应用价值。方法31例临床疑有鼻炎鼻窦炎患者均经CT冠状位扫描,层厚、层距5mm。首次扫描后,如鼻腔或鼻道有实变,在实变侧鼻孔滴入1%麻黄碱滴鼻液3～4滴,体位引流、擤出鼻涕。再行鼻窦扫描,体位、参数同前。CT表现按照改良法分为6型:Ⅰ型漏斗型,Ⅱ型鼻道窦口复合体型,Ⅲ型蝶筛隐窝型,Ⅳ型息肉型,Ⅴ型特发型,Ⅵ型混合型。结果31例中CT表现为:Ⅰ型、Ⅲ型、Ⅴ型各3例,Ⅱ型8例,Ⅳ型5例,Ⅵ型4例。慢性鼻炎5例,伴有中下鼻甲肥大12例,鼻中隔偏曲9例,上颌窦黏膜下囊肿、右侧筛窦黏液囊肿、霉菌性上颌窦炎各2例。使用滴鼻液前,20例鼻腔或鼻道有分泌物影响观察。使用滴鼻液后,鼻腔、鼻甲黏膜收缩,分泌物排出,可明确判定有无息肉存在。2例用药前后扫描分型改变。9例用药前后扫描无明显变化。结论在慢性鼻炎鼻窦炎性病变CT扫描前给予缩鼻黏膜药物,使分泌物排出、黏膜收缩,有助于息肉的显示。更多还原

【Abstract】 Objective To evaluate the utility of nasal mucosa angiotonica during the diagnosis of chronic rhinitis and sinusitis.Methods thirty-one patients with clinically proved chronic rhinitis and sinusitis underwent coronary CT scans of the head with 5 mm of slice thickness and interval.After first scanning,3-4drops of 1% ephedrine naristillae were applied to the nostrils of the consolidation side,then the patients adopted postural drainage and discharged the nasal secretion,simultaneously,CT scans of the accessory nasal sinuses were performed by using same body positions and parameters.CT findings in the group were divided into following six types according to a modified classification such as type I appeared as infundibular,typeⅡ-osteaomeatal units;type-Ⅲ sphenoethmoidal recess,type Ⅳ-sinonasal polyposis,type Ⅴ-idiopathic,and type Ⅵ-mixed pattern.Results Among 31 cases,typeⅠ,Ⅲ and V was found in 3,respective-ly,type Ⅱin 8,type Ⅳ in 5,type VI in 4,and chronic rhinitis in 5.Before using naristillae,nasal cavity secretion had influence on the ob-servation in 20 cases,while after using naristillae,the nasal polyp could be clearly identify due to the contraction of nasal mucosa and the discharge of nasal cavity secretion.After using naristillae,the classifieation in 2 cases changed,while those in 9 cases non-changed.Conclusion The application of nasal mucosa angiotonica in patients with chronic rhinitis and sinusitis before CT scanning led up to contraction of nasal mucosa and discharge of nasal cavity secretion and therefore it is helpful to display the nasal polyp.更多还原
