Sinonasal Symptom Correlation With the Postoperative Polyp Scale (POPS)

Background: Commonly used endoscopic nasal polyp grading scales have been shown to correlate poorly with symptom scores and quality of life metrics. The recently described Postoperative Polyp Scale (POPS) is a grading system that more accurately characterizes polyp recurrence in postoperative sinus cavities by describing incremental recurrence in relation to the surgically opened sinus cavities. Objective: The objective of this study was to determine if the POPS correlated with sinonasal symptoms. Methods: CRSwNP patients were prospectively administered SNOT-22 questionnaires and graded according to the POPS starting at their 1-month postoperative appointments. Total POPS scores (sum of each side) and Max POPS score (larger value of left and right) were correlated with SNOT-22 total scores and subdomains using Kendall correlation testing. Results: A total of 127 patients were enrolled in the study. Both Total POPS or Max POPS were significantly correlated to the SNOT-22 total score (P
