有关NIP的处理素有争论,近20年多主张经鼻侧切开,开放筛窦及内份上颌骨切除术(medial maxillectomy),因如切除不够可有残留,复发率可高达25％～75％,恶变率2％(Osborne),伴生鳞癌率13％(Hyams),故应广泛,完整切除。由于鼻内窥镜的使用,CT、MRI等影像诊断的进展,使术前准确判断肿瘤的部位、范围成为可能,且IP主要源起自鼻侧壁,尤常见为筛窦区和上颌窦口附近,大多发生于单侧,单发成
The treatment of NIP was controversial, more than 20 years advocated by the nasal incision, open ethmoid sinus and internal maxillary excision (medial maxillectomy), because there is not enough to have residual resection, the recurrence rate can be as high as 25% to 75 %, Malignant rate 2% (Osborne), associated with squamous cell carcinoma rate of 13% (Hyams), it should be extensive, complete resection. As the use of nasal endoscopy, CT, MRI and other imaging diagnosis of the progress, so that accurately determine the tumor site before surgery, the scope is possible, and IP originates mainly from the nasal wall, especially the ethmoid sinus and maxillary sinus ostia Near, mostly occurred in one side, single hair into
