Background: Medically refractory chronic rhinosinusitis treated with Endoscopic sinus surgery is a well-established for with a symptomatic success rate ranging from 75% to 98%. Middle meatal dressings are commonly used to reduce postoperative complications. Aim of the work: This study aims to study the effect of absorbable middle meatal spacers in preventing synechia following endoscopic sinus surgery. Patients & Methods: A randomized controlled trial was carried out on 26 cases undergoing endoscopic sinus surgery for the management of bilateral chronic rhinosinusitis in the Otorhinolaryngology. Head and Neck Department, Zagazig University Hospitals. Results: Our results as regard to middle meatal dressing shows statistically significant difference between the absorbable spacers (nasopore) and non absorbable ordinary pack as regards reduction of synechia and adhesion formation after endoscopic sinus surgery. Therefore, middle meatal packing with polyurethane foam (nasopore) is effective in reducing adhesion and synechiae after endoscopic sinus surgery.
Conclusions: Many trials were done to reduce adhesion formation and many different materials had been used for synechiae prevention, one of these materials is middle meatal spacers, one of them is polyurethane foam (nasopore). Packing with polyurethane foam is effective in reducing adhesions after endoscopic sinus surgery a statistically significant difference had been reported between packing with polyurethane foam and Ordinary pack at the middle meatus.
