目的:报告鼻内镜下切除筛窦骨瘤13例(14侧),并探讨相关的技术方法。方法:采用回顾性研究方法,并复习文献进行讨论。13例筛窦骨瘤患者,7例(8侧)术前CT示骨瘤未附着在纸样板、前颅底,在鼻内镜下解剖骨瘤与周围的联系后切除;4例术前CT示骨瘤附着在纸样板、2例术前CT示骨瘤附着在前颅底,在鼻内镜下解剖、暴露骨瘤后用电钻磨除。结果:13例(14侧)筛窦骨瘤在鼻内镜下完整切除,无眶内和颅内并发症,所有患者术腔在6~8周内上皮化。结论:术前冠位加轴位CT扫描能较完整评价骨瘤与筛窦各壁的关系,为手术方法和器械的选择提供有益的帮助;鼻内镜下配合适宜的手术器械,如电钻等切除筛窦骨瘤,无面部瘢痕、创伤小,是经鼻内途径切除筛窦骨瘤的理想选择。
Objective: To report the endoscopic resection of ethmoid sinus tumor in 13 cases (14 sides), and to explore the related technical methods. Methods: Retrospective research methods, and review the literature for discussion. In 13 cases of ethmoid sinusoma, 7 cases (8 sides) of preoperative CT osteoma were not attached to the paper model and anterior skull base, and were dissected after endoscopic sinus surgery. Osteoblast attached to the paper model, 2 cases of preoperative CT osteoma was attached to the anterior skull base, endoscopic anatomy, exposed after osteotomy with electric drill. RESULTS: Thirteen (14) ethmoid sinusomas were completely resected under endoscopic sinus surgery without intraorbital or intracranial complications. All patients underwent epithelialization within 6-8 weeks. Conclusion: The preoperative coronal plus axial CT scan can be a more complete evaluation of the relationship between osteoma and ethmoid sinus wall, for the surgical methods and equipment to provide useful help; endoscopic endoscopic surgery with appropriate equipment such as electric drill Removal of ethmoid sinus tumor, no facial scar, small trauma, is the ideal choice for the removal of ethmoid sinus tumors by intranasal approach.
