Comparison of Two Steroid Nasal Implants Following Endoscopic Sinus Surgery for Chronic Rhinosinusitis

1. The Propel 'implant' is composed of small, flexible tubes which dissolve while releasing Mometasone which is one type of steroid. This application has been approved for use by the FDA. 2. Nasopore soaked with triamcinolone. This "packing' is a sponge‐like material which dissolves while releasing triamcinolone, which is another type of steroid. Triamcinolone has been approved for use topically elsewhere on the body, although the specific use of Triamcinolone in the sinuses has not been approved by the FDA. Both of these procedures are currently used regularly by Dr. Pearlman in practice at the conclusion of ESS for treatment of chronic rhinosinusitis. As standard of care, treatment is determined intraoperatively (during surgery), at the discretion of the surgeon. In this study, each subject will have both treatments (one in each cavity). The 'experimental' aspect relates to directly comparing the two procedures. This research study is being done because there is currently a lack of consensus regarding the optimal nasal packing regimen. There have been no comparison studies and practice patterns vary widely. Our study looks to compare the Propel implant to Nasopore packing soaked in Triamcinolone.
