Abstract：
BACKGROUND: Surgical closure of large nasoseptal perforation (NSP) is challenging. The use of an extended anterior ethmoidal artery (eAEA) flap to reconstruct NSP may present with difficulties for NSPs which have their upper edge in a high position.
METHODS: We propose adding a \"donut-shape\" flap from surrounding septal tissue to the eAEA flap. Thus, the inverted edges of this flap allow to cover the uppermost aspect of the NSP. A series of 18 patients with complete closure of NSPs was included.
CONCLUSIONS: This novel \"Boot-on-Donut\" technique consisting of the eAEA flap (Boot) and inverted edges (Donut) is a feasible procedure that allows to reconstruct large NSP located superiorly.

摘要：
背景：大型鼻中隔穿孔（NSP）的手术闭合具有挑战性。使用扩展的筛动脉前动脉（eAEA）皮瓣重建NSP可能会给上边缘处于高位的NSP带来困难。
方法：我们建议在eAEA皮瓣中增加一个“甜甜圈形”皮瓣。因此，该瓣的倒置边缘允许覆盖NSP的最上面的方面。包括一系列18例NSP完全闭合的患者。
结论：这种由eAEA襟翼（Boot）和倒置边缘（Donut）组成的新颖的“Boot-on-Donut”技术是一种可行的程序，可以重建位于上方的大型NSP。
