上颌和鼻腔恶性肿瘤扩展到眶部时,手术方针的选择是急需研究的问题。作者1970年～1985年施行上颌恶性肿瘤电外科切除186例,其中局部扩展性肿瘤65例施行联合手术:切除部分眶壁和邻近的眶内蜂窝组织40例,眶内容切除25例。肿瘤原发部位:上颌窦39例,筛窦16例,鼻腔9例,上颌牙槽突与硬腭1例。手术范围的确定,作者使用公认的Ohngren氏分类法,考虑肿瘤生长方向,肿瘤原发部位在上颌后上段56例(86.1％),好向眶部生长。上皮性恶性肿瘤48例(73.8％),非上皮性17例(26.2％)。有明显的眼部
When the maxillary and nasal malignancies are extended to the orbit, the choice of surgical guidelines is an urgent need to study. Authors of electrosurgical excision of maxillary malignant tumors from 1970 to 1985 were performed in 186 cases. Among them, 65 cases of locally advanced tumors underwent combined surgery: 40 cases of orbital wall and adjacent orbital cells were resected, and 25 cases of orbital contents were excised. Tumor site: 39 cases of maxillary sinus, ethmoid sinus in 16 cases, 9 cases of nasal cavity, maxillary alveolar process and hard palate in 1 case. The scope of the operation, the authors use the accepted Ohngren's classification, consider the tumor growth direction, the tumor in the upper part of the upper jaw in 56 cases (86.1%), good to the orbital growth. Epithelial malignancies in 48 cases (73.8%), non-epithelial in 17 cases (26.2%). There are obvious eyes
