Juvenile nasopharyngeal angiofibromas (JNAs) are rare, benign, and locally invasive nasopharyngeal tumors. Endoscopic endonasal resection is effective, non-invasive, with low complication rates. Until recently, endoscopic resection was not suitable for intracranially invasive tumors.
PURPOSE/METHOD: We describe resection steps of an intracranially extending JNA with a combined endoscopic endonasal and endoscopic-assisted sublabial transmaxillary approaches. Indications, advantages, and approach-specific complications are also discussed. The main surgical steps are shown in an operative video.
Surgical excision of JNAs by a combined endoscopic endonasal and sublabial transmaxillary approaches represents a safe and effective treatment for selected intracranially invasive JNA.
青少年鼻咽血管纤维瘤（JNAs）是罕见的、良性的、局部侵袭性的鼻咽肿瘤。经内镜鼻内切除术是一种有效、非侵入性的方法，其并发症发生率较低。直到最近，内镜切除术还不适合用于颅内侵袭性肿瘤。
目的/方法：我们描述了一种采用经内镜鼻内和经唇下经口腔上颌窦联合入路切除颅内延伸型 JNA 的步骤。还讨论了适应证、优点和入路相关并发症。主要手术步骤在手术视频中展示。
采用经内镜鼻内和经唇下经口腔上颌窦联合入路切除 JNAs 是治疗特定颅内侵袭性 JNA 的一种安全有效的方法。
