上颌骨掀翻复位术在良性涉颅鼻腔鼻窦肿瘤中的应用

Application of maxillary bone eversion reduction on benign tumor in nasal cavity and paranasal sinus invading the skull base

目的探讨涉颅良性鼻腔、鼻窦肿瘤的手术治疗方法。方法报道６例鼻腔、鼻窦良性肿瘤侵及颅底的病例，其中骨化纤维瘤３例，骨瘤１例，骨软骨瘤１例，骨巨细胞瘤（Ｉ～Ｉ级）１例，均采用１侧上颌骨掀翻复位术及颅面联合进路手术切除肿瘤，全部切除肿瘤４例，近次全切除２例。结果无手术并发症，术后随访２～３年，５例无异常，１例骨化纤维瘤术后２年复发。结论上颌骨掀翻术是一种较好的治疗涉颅良性鼻腔、鼻窦肿瘤的手术方法。

Objective To investigate the operative methods for benign tumors in nasal cavity and paranasal sinus invading the skull base. Methods Six cases of benign tumors in nasal cavity and paranasal sinus invading the skull base were reported.Of them,3 were ossifying fibromas, 1 osteoma, 1 osteoenchondroma and 1 giant osteoid osteoma.The tumors were removed by combined approaches through unilateral maxillary bone eversion reduction.Results No complication was found.Follow up was made 2～3 years after operation. Five cases were uneventful, 1 had a relapse of tumor but still alive.Conclusions The method is appropriate for treating benign tumors in nasal cavity and paranasal sinus invading the skull base.
