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。
Objective: To investigate the diagnostic value of combined fiberoptic nasopharyngoscopy and CT in the detection of small primary nasopharyngeal carcinoma (NPC) and explore its predilection site from the NPC primary small tumor. Methods: 3863 patients with otolaryngological diseases were examined by fiber nasopharyngoscopy. Thirty-six patients with minimal primary nasopharyngeal carcinoma were confirmed by pathology. The patients underwent CT enhanced scanning at the same time, and their primary sites were statistically analyzed. Results: Thirty-six patients were diagnosed nasopharyngeal neoplasm by fiberoptic nasopharyngoscopy combined with CT. There were 25 cases (69.4%) of the primary lesion in the top wall, 9 cases (25.0%) of the posterior wall and 2 cases of the pharyngeal recess 5.6%). CONCLUSION: The tiny primary NPC is more common in the top wall, followed by the posterior wall, and the third is the pharyngeal recess. The combination of fiber nasopharyngoscopy and CT plays an important role in the early accurate diagnosis of NPC.
