The multipoint, impedance-controlled radiofrequency ablation device effectively enhances nasal symptoms and quality of life in chronic rhinitis people, with a favorable safety profile.
A prospective, multicenter, single-arm clinical trial has portrayed compelling evidence for a novel therapeutic approach for chronic rhinitis. The study, which focused on a multipoint, impedance-controlled radiofrequency ablation device targeting the posterior nasal nerve, has shown marked improvements in nasal symptoms and overall quality of life for those suffering from both allergic and nonallergic rhinitis. Overall, 80 adults diagnosed with chronic rhinitis received treatment via radiofrequency ablation device designed to target and ablate the posterior nasal nerve—a key area implicated in the symptoms of rhinitis.
The key outcome was the alteration in the reflective Total Nasal Symptom Score (rTNSS) from the baseline to 6 months after the intervention. Secondary outcomes encompassed changes in the Eustachian Tube Dysfunction Questionnaire (ETDQ-7), the Nasal Obstruction Symptom Evaluation (NOSE) scale, and the mini-Rhinoconjunctivitis Quality of Life Questionnaire (mini-RQLQ), all of which examined various aspects of nasal symptoms and their impact on patients' quality of life. Out of the 80 subjects enrolled, 79 completed the 6-month follow-up. The results were striking, with prominent enhancements witnessed in all primary and secondary outcomes:
Importantly, both allergic and nonallergic rhinitis subgroups portrayed consistent improvements across all measures, with no pivotal differences between these groups, suggesting that the treatment was equally useful for both types of rhinitis. One captivating finding was the correlation between baseline rTNSS scores and treatment outcomes. Those with higher baseline rTNSS scores—indicating more severe symptoms at the start—tended to experience greater improvements at the 6-month follow-up.
The safety of the device was also scrutinized, with the key safety endpoint being the incidence of severe adverse events linked with the intervention. The study reported 1 serious adverse event: a case of epistaxis (nosebleed). With its ability to offer lasting symptom relief, the multipoint, impedance-controlled radiofrequency ablation device represents a potentially transformative remedy for chronic rhinitis.
