报告首诊为鼻息肉的鼻腔和鼻窦肿瘤12例。其中内翻性乳突状瘤和筛窦鳞癌各3例，鼻腔鳞癌2例，腺样囊性癌、嗅神经母细胞瘤、脑膜瘤和粘液表皮样癌各1例。鉴于肿瘤有可能与鼻息肉并存，认为对鼻息肉患者；①应先充分收缩鼻腔粘膜后以枪状镊拨开息肉，观察其周围和深部情况，有条件时应常规行鼻内窥镜检查；②对可疑病变术前应常规取材送病检。鼻息肉恶变可能与手术的反复刺激有关．因此应力求在鼻内窥镜下一次性彻底切除息肉，清除病变组织，建立良好的鼻窦引流通道，并配以术后综合治疗，尽量避免息肉复发。
Nasal polyps nasopharyngeal and nasal tumors reported in 12 cases. Including inverted papilloma and ethmoid sinus squamous cell carcinoma in 3 cases, 2 cases of nasal squamous cell carcinoma, adenoid cystic carcinoma, olfactory neuroblastoma, meningioma and mucoepidermoid carcinoma in 1 case. In view of the tumor may co-exist with the nasal polyps, that the patients with nasal polyps; ① nasal mucosa should be fully contracted by gun tweezers to open the polyp to observe the surrounding and deep conditions, conditions should be routine nasal endoscopy; ② preoperative suspicious lesions should be routinely taken for disease detection. Malignant changes in nasal polyps may be related to the repeated stimulation of surgery. Therefore, we should try to complete a one-time radical resection of polyps in nasal endoscopy, removal of diseased tissue, and establish a good sinus drainage channels, combined with postoperative comprehensive treatment, try to avoid recurrence of polyps.
