鼻咽癌是耳鼻咽喉科常见的恶性肿瘤之一,首次就诊时,中耳积液所致的症状可能是唯一主诉。由于原发病灶部位深而隐蔽,往往误诊渗出性中耳炎。现将我们所遇3例报告如下,并对鼻咽癌致中耳积液的原因作一探讨。 例1,男,45岁,右耳听力下降5个月,鼓膜穿刺抽出积液,诊断“分泌性中耳炎”,治疗二月后复查,右中耳仍有积液。鼻咽部检查:鼻咽顶部右侧有光滑隆起,颈部无肿大淋巴结。鼻咽部活检:粘膜慢性炎症 Nasopharyngeal carcinoma is one of the most common malignant tumors of the otorhinolaryngology department.
