Abstract
BACKGROUND: Temperature-controlled radiofrequency (TCRF) neurolysis of the posterior nasal nerve (PNN; RhinAer) is a minimally invasive treatment option for patients with chronic rhinitis. OBJECTIVE: To determine clinical outcomes and quality of life (QoL) following TCRF neurolysis of the PNN. METHODS: A prospective single-arm study of 129 patients with chronic rhinitis at 16 medical centers in the United States and Germany. RESULTS: = .002 comparing 3 and 6 months). This represents 53.8% improvement over baseline at 3 months and 62.8% improvement at 6 months. Rhinorrhea, congestion, sneezing, and itching subscores and postnasal drip and cough scores were all significantly improved over baseline at both timepoints. At 3 months, 76.2% (95% CI, 68.1%-82.8%) of patients achieved a minimal clinically important difference of ≥30% improvement in rTNSS over baseline and the percentage was higher at 6 months (83.5% [95% CI, 75.8%-89.0%]). At 3 months, 80.3% (95% CI, 72.6%-86.3%) reported a minimal clinically important difference of ≥0.4-point improvement in the mini rhinoconjunctivitis quality of life questionnaire score, and the percentage was higher at 6 months; 87.7% (95% CI, 80.7%-92.4%). There were no serious adverse events with a relationship to the device/procedure reported through 6 months. CONCLUSION: In this large, multicenter study, TCRF neurolysis of the PNN was safe and resulted in a significant reduction in rhinitis symptom burden at 3 months that was sustained/improved through 6 months. The majority of patients reported a clinically relevant improvement in QoL at 3 and 6 months postprocedure.
