PURPOSE OF REVIEW Nasoseptal flaps are a frequently used and well characterized means of reconstruction following endoscopic endonasal approach surgery (EEA). However, there are alternative means of reconstruction, including the extracranial pericranial flap (ePCF), that while used infrequently fulfill a specialized need in larger or salvage reconstructions. This review aims to better characterize long-term outcomes using ePCF where there is currently a paucity of objective data on use and outcomes. RECENT FINDINGS A traditional pericranial flap involves elevating and rotating the flap through a craniotomy defect to reconstruct defects of the ventral skull base. The ePCF is implemented without performing a craniotomy, and instead tunnels the flap through a bony opening created at the level of the nasion. This review presents outcomes in a large single-center cohort of patients with ePCFs to better characterize the short- and long-term success, risks, and complications of this reconstructive method. SUMMARY Long-term follow-up demonstrates that obstruction of the frontal sinus outflow may occur but rarely requires surgical intervention. ePCF are a reasonable alternative to consider in cases where local tissue would be insufficient, is not available, or has already failed. There is a low risk of flap complications.

颅底重建中颅外颅周皮瓣的长期并发症。


综述目的 鼻中隔皮瓣是内窥镜鼻内入路手术 （EEA） 后一种常用且特征明确的重建方法。然而，还有其他重建方法，包括颅外颅周皮瓣 （ePCF），虽然不经常使用，但可以满足大型或挽救性重建的特殊需求。本综述旨在更好地描述使用 ePCF 的长期结局，因为目前缺乏关于使用和结局的客观数据。最近的发现 传统的颅周皮瓣涉及通过开颅缺损抬高和旋转皮瓣，以重建腹侧颅底的缺损。ePCF 是在不进行开颅手术的情况下实施的，而是通过在鼻孔水平创建的骨开口将皮瓣隧道化。本综述介绍了 ePCF 患者大型单中心队列的结果，以更好地描述这种重建方法的短期和长期成功、风险和并发症。摘要 长期随访表明，额窦流出道可能发生阻塞，但很少需要手术干预。ePCF 是局部组织不足、不可用或已经失败的情况下考虑的合理替代方案。皮瓣并发症的风险很低。
