Abstract：
As the indications for endoscopic skull base approaches have increased, so has the need for more versatile vascularized flaps for skull base reconstruction. Here, we describe a novel lateral based nasopharyngeal flap (LNPF). Two cadaver heads were dissected to elucidate flap anatomy, dimensions, and technique. A retrospective review was performed on two cases where LNPF was used to repair CSF leaks in the nasopharyngeal area, and outcomes reported. The LNPF is an ascending pharyngeal artery myomucosal flap that includes the nasopharyngeal mucosa and the superior pharyngeal constrictor muscle. The flap was 1.2 × 2.2 cm in greatest dimensions. The LNPF was used for salvage CSF leak repair in two cases: one clival and one tubal. Both patients had resolution of leak at 7 months follow-up. The LNPF is a novel flap with reconstruction potential for the nasopharynx, including the lower clivus and the eustachian tube.
摘要：
随着内窥镜颅底入路适应症的增加，因此需要更多功能的血管化皮瓣进行颅底重建。这里,我们描述了一种新型的鼻咽侧基皮瓣（LNPF）。解剖了两个尸体头部以阐明皮瓣解剖结构，尺寸,和技术。对2例使用LNPF修复鼻咽区脑脊液漏的病例进行了回顾性研究，和报告的结果。LNPF是一种升咽动脉肌粘膜瓣，包括鼻咽粘膜和上咽缩肌。皮瓣最大尺寸为1.2×2.2cm。在两种情况下，LNPF用于挽救性CSF泄漏修复：一种是斜坡，一种是输卵管。两名患者在7个月的随访中均有渗漏消退。LNPF是一种新颖的皮瓣，具有重建鼻咽部的潜力，包括下斜坡和咽鼓管。
