At the end of surgery, patients were randomized to receive Chitogel to one side of the sinuses (allowing the other side to serve as control). Patients underwent routine follow\u2010up with nasoendoscopies performed at 2, 6, and 12 weeks postoperatively. Sinus ostial measurements, microbiology, and microbiome swabs from bilateral sides were collected intraoperatively and at 12 weeks postoperatively.

A significant decrease in infections on the Chitogel side (12.0%) compared with control (52.0%) (<jats:italic>p<\/jats:italic> = 0.005) was evident.
