Surgical technique report demonstrates an extended anterior ethmoidal artery flap for large septal perforations, highlighting an approach to provide sufficient mucosal coverage.
INTRODUCTION Pedicled endonasal flaps are currently the most widespread techniques with high success rate in the treatment of septal perforations (SPs). However, complete closure of large SPs (>2 cm) is technically more challenging with high risk of recurrence. Few endonasal flaps provide sufficient tissue for large SPs and usually are based on complex techniques or with higher morbidity. The anterior ethmoidal artery (AEA) flap is the most widely used endoscopic techniques; however, it does not repair large SPs. The objective of this study is to describe step by step an innovative technique to repair large SP with a pure endoscopic extended AEA flap which includes the mucosa of sphenoid rostrum and the inferior meatus. In addition, we added a radiological study showing the additional area. This is the first report in the literature of an extended AEA flap.
