目的介绍经内镜下斜坡脊索瘤切除的手术方法,探讨内镜在下斜坡脊索瘤手术中的应用价值。方法 3例下斜坡脊索瘤,均采取内镜引导下经口.咽后壁入路进行肿瘤切除。结果术后 MRI 显示2例肿瘤获得全切,1例次全切除;患者术后均未出现严重并发症,无手术后遗症;术后随访6个月～2年,1例术后1年死亡,2例无瘤生存。结论内镜引导下经口-咽后壁入路切除下斜坡脊索瘤具有手术径路短,周围组织结构损伤小,术后恢复快,无严重并发症和后遗症等优点;特别是采用不同视角的内镜能显示并切除其他手术方法所不能显示的位于隐蔽解剖区域的病变,更有利于肿瘤的彻底切除,是切除下斜坡脊索瘤较好的手术方法。
Objective To introduce the surgical method of endoscopic resection of chordoma, and to explore the value of endoscopy in the surgical treatment of chordoma. Methods Three cases of chordoma under the slope, were taken under the guidance of endoscopic guidance. Pharyngeal wall approach for tumor resection. Results Postoperative MRI showed complete resection of 2 cases and complete subtotal resection in 1 case. No severe complications were found after operation, and sequelae were not observed. The patients were followed up for 6 months to 2 years and 1 case died after 1 year. Two patients survived without tumor. Conclusion Under the guidance of endoscope, resection of inferior chordoma with trans-pharyngeal posterior wall has the advantages of short operative path, less damage to the surrounding tissue structure, rapid postoperative recovery, no serious complications and sequelae, especially in different angles of view Mirror can show and excision of other surgical methods can not be displayed in the hidden anatomical lesions, but also conducive to the complete removal of the tumor, resection of the lower chordoma is a better surgical method.
