Clinical benefits of polyurethane nasal packing in endoscopic sinus surgery.

The benefits of nasal packing after endoscopic sinus surgery (ESS) are still debated in the literature. Our aims were to evaluate the efficacy, and the clinical effects of a totally degradable nasal dressing used after ESS. Thirty patients with chronic rhinosinusitis with nasal polyps were enrolled in a prospective, randomized, double-blind, controlled study. Every patient underwent ESS and a polyurethane nasal dressing was used in one nasal fossa and the contralateral fossa was left unpacked. The extent of mucosal edema, crust formation, bleeding tendency, presence of synechiae, amount of nasal discharge, and the patency of the ostiomeatal complex (OMC) was evaluated during nasal endoscopy on the first, fourth, and twelfth postoperative weeks. All clinical findings were statistically analyzed. Endoscopy showed a significant improvement in the patency of the OMC on the side with resorbable material at 4 weeks after surgery. Follow-up at week 12 showed that in addition to the OMC patency scores, synechia formation and nasal discharge were also significantly improved in the packed fossa. Polyurethane packing is an effective alternative for nasal packing following functional endoscopic sinus surgery.
