报告4725例纤维鼻咽镜的检查结果，镜下诊断为慢性炎症、正常鼻腔鼻咽、鼻咽癌分别占6597％、14．41％和10．96％，居前三位。纤维鼻咽镜确诊率及对慢性炎症、鼻咽癌确诊率显著高于间接鼻咽镜．P值＜0，001。对鼻咽囊肿的诊断，纤维鼻咽镜确诊率高于间接鼻咽镜，但无统计学差异。提出纤维鼻咽镜对鼻咽鼻腔疾病的诊断尤其是结合VCA－Iga检查对鼻咽癌的早期诊断具有较高的价值。 Report of 4725 cases of fiber nasopharyngeal examination results, microscopic diagnosis of chronic inflammation, normal nasopharyngeal, nasopharyngeal carcinoma accounted for 6597%, 14.41% and 10.96%, the top three. Diagnosis of fiber nasopharyngeal and chronic inflammation, nasopharyngeal carcinoma was significantly higher than the indirect diagnosis of nasopharyngeal. P value <0,001. The diagnosis of nasopharyngeal cysts, fiber nasopharyngeal diagnosis rate higher than indirect nasopharyngeal, but no statistical difference. It is suggested that the diagnosis of nasopharyngeal nasal cavity diseases by fiber nasopharyngoscopy is of high value especially in the early diagnosis of nasopharyngeal carcinoma in combination with VCA-Iga examination.
