【摘要】 目的:探讨纤维鼻咽镜与CT联合检查对鼻咽癌(NPC)微小原发灶的诊断价值,并从NPC微小原发灶探讨其好发部位。方法:用纤维鼻咽镜检查耳鼻咽喉疾病患者3863例,经病理证实发现其中36例为鼻咽部微小原发癌患者,这些患者同时进行CT增强扫描,并就其原发部位进行统计分析。结果:36例患者经纤维鼻咽镜与CT联合检查发现鼻咽肿瘤,原发病灶位于顶壁者25例(69.4%),后壁者9例(25.0%),咽隐窝者2例(5.6%)。结论:NPC微小原发灶多见于顶壁,其次是后壁,第三是咽隐窝。纤维鼻咽镜与CT联合应用对NPC的早期准确诊断具有重要作用。更多还原

【Abstract】 Objective:To explore the value of nasopharygo-fiberscope and CT in diagnosing microfacal Nasophryngeal Carcinoma(NPC)and the prevalent area,the nasopharynx,where the NPC usually initially developed from.Method:From October,2003 to October,2005,the data of original microfocus of 36 pathologically confirmed NPC were reviewed retrospectively.These cases were examined by nasopharygo-fiberscope and CT strengthening scanning.Result:On clinical examination,only 2 cases(5.6%)were found to have original micro-tumor in the recess,the other 34 cases(94.4%)had developed from the other regions including 25(69.4%)from the roof and 9 cases(25.0%)from the posterior wall,all with smooth and symmetrical mucosa in the recess.Positive rate of nasophryngeal mass were 100% by nasopharygo-fiberscope and by CT.Conclusion:The data suggested that the roof of nasopharyngeal cavity be the most possible area that the original NPC micro-focus developed from,followed by the posterior wall and the recess.eNasopharygo-fiberscope and CT is very helpful for the correct clinical diagnosis of NPC.更多还原
