Introduction: Endoscopic sinus surgery (ESS) is themainstay for treatment of chronic rhinosinusitis versusmaximal medical therapy. We propose a more economicaloption, by using steroid-impregnated Gelfoam instead ofNasopore post ESS, as it is less expensive and has showedeffectiveness in preventing post-operative bleeding.Materials and methods: A randomised, double-blinded,placebo-controlled trial was carried out in eight patients with chronic rhinosinusitis or nasal polyposis who were planned for bilateral endoscopic sinus surgery. A Peri-operative Sinus Endoscopy (POSE) Score and Lund-KennedyEndoscopic Score (LKES) were recorded. The use ofhydrocortisone-impregnated Gelfoam dressing versusnormal saline-impregnated Gelfoam dressing werecompared. Scores were repeated post-operatively at oneweek, three weeks and three months interval.Results: For LKES, at the end of three months, 50% of thepatients had the same score difference, 37.5% had betterresults on the study side while 12.5% had better results onthe control side. Meanwhile, for POSE Score, at the end ofthree months, 75% of the patients had better scoredifference on the study side while 12.5% had better resultson the control side.Conclusion: Gelfoam can be used as nasal packing materialto deliver topical steroid after endoscopic sinus surgery.Steroid-impregnated nasal dressing after endoscopic sinussurgery may not provide better long-term outcome.
