目的:探讨颞下窝及翼腭窝区侧颅底受累头颈肿瘤的手术进路及疗效。方法:2005年4月～2009年6月,15例颞下窝及翼腭窝区肿物并同时伴有侧颅底受累的患者在中山大学孙逸仙纪念医院口腔颌面外科进行手术治疗。采用颅面联合入路10例、颞下窝入路3例,Weber-Ferguson加Lynch入路2例。结果:15例患者肿瘤全部切除,11例同期行颅底软硬组织缺损的修复。无手术死亡,无术后偏瘫或脑脊液漏。结论:颞下窝及翼腭窝区颅底受侵肿物的手术入路应视肿瘤部位及颅脑组织受影响的程度而定。肿瘤切除同时行缺损修复可降低手术风险及并发症的发生。
OBJECTIVE: To investigate the surgical approach and efficacy of lateral head skull base tumors in the infratemporal fossa and pterygopalatine fossa. METHODS: From April 2005 to June 2009, 15 cases of tumors in the infratemporal fossa and pterygopalatine fossa were involved in surgical treatment of oral and maxillofacial surgery at Sun Yat Sen Memorial Hospital, Sun Yat-Sen University. There were 10 cases of craniofacial joint approach and 3 cases of infratemporal fossa approach, and 2 cases of Weber-Ferguson plus Lynch approach. RESULTS: All 15 cases had tumor resection and 11 cases were repaired with soft and hard tissue defects at the skull base. No operative death, no postoperative hemiplegia or cerebrospinal fluid leakage. CONCLUSIONS: The approach to the invasion of skull base in the infratemporal fossa and pterygopalatine fossa should be determined by the degree to which the tumor site and brain tissue are affected. Simultaneous resection of tumor at the time of tumor resection can reduce the risk of surgery and the occurrence of complications.
