目的：探讨采用经上颌骨翻转入路手术切除颅底肿瘤的方法及术后并发症。方法：采用经一侧上颌骨掀翻入路切除3例颅底肿瘤,其中鼻咽巨大纤维血管瘤1例；翼腭窝平滑肌肉瘤1例；鼻口咽部非霍奇金恶性淋巴瘤1例。结果：3例患者均无上颌骨坏死和面部畸形、无错位咬合、无面神经功能障碍和下睑外翻、无术侧面部感觉障碍和溢泪、无脑脊液漏及颅内外感染。但2例出现术侧分泌性中耳炎、有轻度张口受限。结论：经一侧上颌骨掀翻入路行颅底手术具有显露充分、肿瘤切除彻底、正常功能结构及外观影响小的优点。
Objective: To explore the method of transcranial maxillofacial surgery for the removal of skull base tumors and postoperative complications. Methods: Three cases of skull base tumors were excised via one maxillary overturning approach, including 1 case of giant fibrosarcoma of the nasopharynx, 1 case of leiomyosarcoma of the pterygopalatine fossa, 1 case of nasopharyngeal non-Hodgkin’s lymphoma . Results: All the 3 patients had no maxillary necrosis and facial deformity, no dislocation occlusion, no facial nerve dysfunction and lower eyelid eversion, no facial side sensory and overflow tears, no cerebrospinal fluid leakage and intracranial infection. However, 2 cases of surgical side secretory otitis media, mild mouth restriction. CONCLUSIONS: Skull base operation with maxillary overturning on one side has the advantages of adequate exposure, thorough tumor resection, little effect of normal functional structure and appearance.
