Two‐year outcomes of temperature‐controlled radiofrequency device treatment of the nasal valve for patients with nasal airway obstruction

Abstract Background The objective of this study was to evaluate long‐term symptom improvements in patients with nasal airway obstruction (NAO) secondary to nasal valve collapse (NVC) following minimally invasive temperature‐controlled radiofrequency (TCRF) treatment. Methods A prospective, single‐arm, multicenter study in patients >18 years with NAO due to NVC. Inclusion criteria were response to nasal valve dilation (e.g., modified Cottle maneuver) and baseline Nasal Obstruction Symptom Evaluation (NOSE) Scale score ≥60. Patients were treated in the nasal valve region with a TCRF device and followed through 2 years. A responder was ≥20% reduction NOSE Scale score or ≥1 reduction in severity class. Results A total of 122 patients were treated and 91 reached 2 years. The mean baseline NOSE Scale score was 80.3 (95% CI, 78.1–82.6). The adjusted mean change in score at 2 years was −45.8 (95% CI, −53.5 to −38.1), p
