"Boot-on-Donut" procedure for anterior and large septal perforation.

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. METHOD: 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. CONCLUSION: 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.
