目的 :探讨应用 L e Fort 型截骨进路切除侵入翼腭窝、颞下窝的巨大鼻咽纤维血管瘤的可行性。方法 :回顾性分析 2 0 0 0年 7月～ 2 0 0 2年 1月采用 L e Fort 型截骨进路手术切除 3例侵入翼腭窝、颞下窝鼻咽纤维血管瘤的临床资料。结果 :3例均为男性 ,年龄 13～ 19岁 ,术前均行单侧或双侧超选择性动脉栓塞 ,手术均经 L e Fort 型戴骨进路行肿瘤切除术 ,术后除 1例因左眼内直肌损伤出现视物轻度重影外 ,无其它手术并发症。术后病理诊断均为纤维血管瘤。术后经 2～ 18个月随访 ,3例病人均咬合良好 ,无肿瘤复发。结论 :L e Fort 型截骨进路是处置侵入翼腭窝、颞下窝的巨大鼻咽纤维血管瘤的较好手术进路之一。
OBJECTIVE: To investigate the feasibility of using L e Fort osteotomy approach to remove giant nasopharyngeal fibrovascular tumors that invade the pterygopalatine fossa and infratemporal fossa. Methods: The clinical data of 3 cases of infiltrating the pterygopalatine fossa and infratemporal fossa nasopharyngeal fibroadenoma by L e Fort osteotomy approach were retrospectively analyzed from July 2000 to January 2002. Results: All the 3 patients were male, aged 13 to 19 years. One or two sides of superselective arterial embolization were performed before operation. All the patients underwent L e Fort type of wearing bone approach for tumor resection. One case Because of left eye rectus muscle injury appeared mild visual ghosting, no other surgical complications. Postoperative pathological diagnosis of hemangiomas. After 2 to 18 months follow-up, 3 patients were well bite, no tumor recurrence. CONCLUSION: L e Fort-type osteotomy approach is one of the better surgical approaches for the treatment of huge nasopharyngeal fibrovascular tumors that invade the pterygopalatine fossa and infratemporal fossa.
