Abstract

Background: In the absence of direct evidence supporting how to use nasal endoscopy findings to judge chronic rhinosinusitis (CRS) disease control, experts' practice patterns could provide guidance. Methodology: Participants consisted of a diverse group of twenty-nine rhinologists. Participants were presented with every possible combination of bilateral nasal endoscopy findings represented by the modified Lund-Kennedy (MLK; range: 0–12) endoscopic scoring system and Nasal Polyp Score (NPS; range: 0–8). Reflecting the practical consequence of CRS disease control assessment, participants were asked whether they would consider CRS treatment escalation based on each scenario in the absence of any CRS symptoms, and how strongly they considered escalating therapy. The same scenarios were then presented in the context of 1 burdensome CRS symptom and participants again were asked whether they would consider treatment escalation. Results: The median threshold total MLK score for considering treatment escalation was ≥4 and 75.9% of participants’ MLK thresholds were within 1 point of 4. The median threshold total NPS for considering treatment escalation was ≥3 and 62.5% of participants’ NPS thresholds were within 1 point of 3. Endoscopy score thresholds decreased in the presence of 1 burdensome symptom and generally increased when requiring stronger affirmation for considering CRS treatment escalation. Conclusion: Reflecting the practice patterns of a diverse group of rhinologists, MLK score ≥4 or NPS ≥3 may serve as thresholds for considering CRS treatment escalation. Alternatively, MLK score <4 or NPS <3 may serve as endoscopic goals of CRS treatment. These results provide guidance for using nasal endoscopy findings as a criterion of CRS disease control.
