Nasal Polyps

Brief summary

Prior studies have suggested that topical furosemide may reduce the recurrence of sinonasal polyposis following sinus surgery. This project aims to further investigate that claim through a blinded randomized controlled clinical trial following patients who undergo functional sinus surgery for chronic rhinosinusitis with sinonasal polyposis by randomly assigning participants to receive topical furosemide versus placebo nasal spray for 2 months post operatively. Outcomes would be compared at 6 months through endoscopic grading scores using Lund Kennedy and Meltzer scores as well as Sino-Nasal Outcome Test (SNOT-22) scores to measure the rate and degree of recurrence and impact on symptoms in the treatment group versus placebo.

Outcome results

Primary

Polyp Recurrence

Nasal and paranasal polyposis based on endoscopic grading through Lund Kennedy score to measure the rate and degree of recurrence.

Time frame: 6 months

Population: This data was not collected and therefore no data analysis was done due to the study being terminated early secondary to 1) low enrollment due to the emergence of better medical alternatives to treat polyps (ie. Biologics) which made using furosemide not useful and 2) COVID.
