鼻腔鼻窦病变CT扫描与鼻内窥镜检查的对照观察

目的　比较CT和鼻内窥镜 (nasalendoscope ,NE)对鼻腔和鼻窦病变的诊断价值 ,为临床诊断提供理论依据。方法　收集80例同一时期内具有鼻腔鼻窦区CT和鼻内窥镜检查结果 ,并得到病理证实的病例 ,对两者进行对照分析。结果　CT、NE的检查结果与病理结果对照 ,鼻窦炎、鼻窦肿瘤诊断正确率相似 ,鼻腔、鼻窦息肉、鼻腔肿瘤、鼻甲肥大NE诊断正确率高于CT ,副鼻窦体的解剖变异、鼻窦囊肿CT高于NE。结论　NE可以了解病变的形状、质地、颜色 ,并可在镜下活检 ,有助于病变的定性。CT可以了解病变的大小、形状和病变与邻近解剖结构的关系 ,两者互补可更全面诊断病变

Comparative Study of CT and Nasal Endoscope(NE) in Diagnosis of Lesions of Nasal Cavity and Paranasal Sinu

Objective To compare the diagnostic value of CT and NE for lesions of nasal cavity and paranasal sinus area.Methods 80 cases of nasal and paranasal sinus diseases which were examined by both CT and NE at same period and proved by pathology.were reviewed.Results Compare with results of pathology,the accucy rate of both CT and NE was identical in diagnosing sinusitis and tumours of paranasal sinus,NE was higher than CT in nasal and paranasal sinus polyp and nasal cavity tumour,turbinate hyperplasia CT was higher than NE in paranasal sinus cyst and anatomic variations.Conclusion Pathologic biopsy can be taken under NE guide to understand the shape,texture and colour of the illness focus CT can show the size,shape and anatomy relation between lesion and its neighbor tissue.The diagnosis may more perfectly through NE combined with CT.
