EDS is more effective than NS in topical delivery to the NP and ET orifices in cadavers. Targeted ESS may facilitate greater NP penetration by EDS compared to NS, with possible synergism after ESS for augmented delivery. These findings suggest a role for EDS delivery methods for ETD management and in CRS+ETD patients undergoing sinus surgery. This article is protected by copyright. All rights reserved.
