Summary
A new grading scale, the Postoperative Polyp Scale (POPS), accurately assesses nasal polyp recurrence after surgery. This reliable tool aids in evaluating treatments for chronic rhinosinusitis with nasal polyps.
Area of Science:
- Otolaryngology
- Rhinology
- Medical Device Development
Background:
- Current endoscopic grading scales inadequately assess postoperative nasal polyposis.
- Accurate assessment of polyp recurrence is crucial for managing chronic rhinosinusitis with nasal polyps (CRSwNP).
Purpose of the Study:
- To develop and validate a novel endoscopic grading system, the Postoperative Polyp Scale (POPS).
- To improve the characterization of polyp recurrence in postoperative paranasal sinus cavities.
Main Methods:
- A modified Delphi method involving 13 otolaryngologists, rhinologists, and allergists established the POPS.
- Fellowship-trained rhinologists reviewed 50 postoperative endoscopy videos from CRSwNP patients using the POPS.
- Test-retest and inter-rater reliability were assessed for the POPS.
Main Results:
- The POPS demonstrated good inter-rater reliability (Kappa = 0.49-0.50).
- Excellent test-retest reliability was observed (Kappa = 0.80).
Conclusions:
- The POPS is a reliable and objective endoscopic grading scale for postoperative polyp recurrence.
- This novel scale can aid in measuring the efficacy of medical and surgical interventions for CRSwNP.
