目的:探讨上颌骨LeFortI型截骨进路切除累及翼腭凹、颞下凹巨大鼻咽纤维血管肿瘤的可行性。方法:采用矫正上颌骨先天或后天畸形的LeFortI型截骨术式进路,切除位于鼻咽部、筛窦等深在部位的纤维血管瘤。结果:该进路术野显露充分,取得了理想的治疗效果。结论:上颌骨LeFortI型截骨进路是切除鼻咽、颅底部纤维血管瘤的理想进路。
OBJECTIVE: To investigate the feasibility of maxillary LeFortI osteotomy approach for the treatment of giant nasopharyngeal fibrovascular tumors involving the pterygopalatine fossae and the infratemporal fossa. Methods: LeFortI type osteotomy approach was used to correct the congenital or acquired maxillary deformity. The hemangiomas located in the deep nasopharynx and ethmoid sinus were removed. Results: The surgical field revealed fully, and achieved the desired therapeutic effect. Conclusion: Maxillary LeFortI osteotomy approach is the ideal approach for resection of nasopharyngeal and skull base fibrovascular tumors.
