This study evaluated the outcomes of patients with refractory chronic rhinitis treated with temperature-controlled radiofrequency neurolysis. The results showed significant improvement in symptoms, and the treatment was found to be safe with no serious adverse events. The data suggest that this novel device could be a minimally invasive option for treating chronic rhinitis.
Background Chronic rhinitis is a prevalent condition with a significant impact on quality of life. Posterior nasal nerve and vidian neurectomy are surgical options for treating the symptoms of chronic rhinitis but are invasive procedures. Objective To determine the outcomes of patients diagnosed with refractory chronic rhinitis and treated with temperature-controlled radiofrequency neurolysis of the posterior nasal nerve area in a minimally invasive procedure. Methods A prospective, single-arm multicenter study with follow-up through 52 weeks. Eligible adult patients had chronic rhinitis symptoms of at least 6 months duration with inadequate response to at least 4 weeks usage of intranasal steroids and an overall 12-h reflective total nasal symptom score (rTNSS) >= 6 with subscores 2 to 3 for rhinorrhea, 1 to 3 for nasal congestion, and 0 to 3 for each of nasal itching and sneezing. Temperature-controlled radiofrequency energy was delivered to the nasal cavity mucosa overlying the posterior nasal nerve region with a novel single-use, disposable, handheld device. Results A total of 50 patients were treated (42.0% male; mean age 57.9 +/- 11.9 years), and 47 completed the study through 52 weeks. Mean rTNSS significantly improved from 8.5 (95% CI 8.0, 9.0) at baseline to 3.6 (95% CI 3.0, 4.3) at 52 weeks (P < .001), a 57.6% improvement. Similar trends in improvement were noted for rTNSS subscores (rhinorrhea, nasal congestion, itching, sneezing), postnasal drip scores, and chronic cough scores. Subgroup analysis demonstrated the treatment was effective regardless of rhinitis classification (allergic or nonallergic). No serious adverse events with a relationship to the device/procedure occurred. Conclusions Temperature-controlled radiofrequency neurolysis of the posterior nasal nerve area for the treatment of chronic rhinitis is safe and resulted in a durable improvement in the symptoms of chronic rhinitis through a 52-week follow-up. Data suggest that this novel device could be considered a minimally invasive option in the otolaryngologist's armamentarium for the treatment of chronic rhinitis.
