为进一步探讨内窥镜检查对鼻咽疾患的早期诊断价值，作者应用接触式显微内窥镜配以高清晰度电视摄像系统，结合活体染色，直接动态观察２２０例鼻咽正常或不同病变受检者鼻咽粘膜上皮的微观形态。接触式显微内窥镜最大放大倍数１５０倍，连接长焦摄像镜头后图像可放大４００倍，能较清晰地显示粘膜上皮表层原位细胞的形态结构及分布排列情况，还能对粘膜毛细血管的形态及血细胞流动情况进行观察。初步观察结果显示：正常鼻咽粘膜上皮细胞排列较规则，多为柱状上皮细胞；鼻咽炎症的粘膜上皮细胞排列多不规则，脱落细胞较多，血管扩张，常见有鳞状细胞化生；鼻咽癌病灶染色不均，表层细胞形态及排列极不规则，微血管扩张、曲张，易出血。
To further explore the value of endoscopy for the early diagnosis of nasopharyngeal diseases, the author applied contact micro-endoscope with high-definition television camera system, combined with living staining, direct dynamic observation of 220 cases of nasopharyngeal normal or different lesions The microscopic morphology of the nasopharyngeal mucosa epithelium of the examinee. The maximum magnification of contact micro-endoscope 150 times, connecting the telephoto camera lens can magnify the image 400 times, can clearly show the mucosal epithelial cells in situ morphology and distribution of the arrangement, but also mucosal capillaries The morphology and blood flow were observed. Preliminary observations showed that: normal nasopharyngeal mucosa epithelial cells arranged more regular, mostly columnar epithelial cells; nasopharyngeal inflammation mucosal epithelial cells arranged more irregular, more exfoliated cells, vasodilation, common squamous metaplasia; nasal Pharyngeal lesions uneven staining, the surface cells arranged in a very irregular shape, capillaries dilated, varicose, bleeding easily.
