    Improved nasal airway obstruction (NAO) symptoms were reported at 3 months following temperature-controlled radiofrequency (TCRF) treatment of the septal swell body (SSB). This report provides results from assessments of the long-term safety and efficacy of TCRF treatment of SSB hypertrophy to treat NAO through 12 months posttreatment. This prospective, multicenter, long-term, open-label study was conducted in nine centers within the United States and included patients with severe/extreme NAO attributed to SSB hypertrophy. Outcome measures included assessments of Nasal Obstruction Symptom Evaluation Score (NOSE), Numeric Rating Scale (NRS) ease-of-breathing, patient satisfaction, and adverse events at 6 and 12 months. Of the 70 patients treated, 65 and 62 patients completed the 6- and 12-month follow-up assessments. Compared to baseline, there was a 67.5% decrease in adjusted mean NOSE scores at 6 months (mean change -49.6, 95% confidence interval [CI] -54.8 to -44.4; p < 0.001) and a 65.4% decrease at 12 months (mean change -48.1, 95% CI -53.7 to -42.5); p < 0.001), which is consistent with previously published 3-month results. A 62.0% and 62.5% improvement compared to baseline was observed in the NRS ease-of-breathing score at 6 and 12 months, respectively (p < 0.001). No serious adverse were reported overall and no new device- or procedure-related adverse events were reported in the interval between 3 and 12 months posttreatment. TCRF treatment of SSB hypertrophy has a significant and durable effect on improving the symptoms of NAO and health-related quality of life in patients with symptoms of nasal obstruction and congestion through 12 months postprocedure. © 2024 The Author(s).
