Effectiveness of Kinetic Oscillation Stimulation Treatment in Patients with Non-Allergic Rhinitis Refractory to Conventional Medical Therapies

Abstract

1.1. Introduction: Kinetic Oscillation Stimulation (KOS) is a new treatment for symptoms of non-allergic rhinitis (NAR). The aim of the study was to investigate effectiveness of KOS treatment in patients affected by NAR. 1.2. Methods: From December 2018 to July 2020, 39 patients, already refractory to conventional medical therapy, were treated with KOS. As control group, we considered a group of 41 patients treated with topical mometasone furoate, observed in the same period and number of days. During the ENT visit, objective examinations were performed to assess respiratory function. In addition, all the subjects filled out quality of life (QoL) questionnaires. All patients were reevaluated after 45 days. 1.3. Results: All the instrumental assessments and QoL questionnaires showed a significant improvement 45 days after KOS treatment. Sixteen patients (43%) reported an improvement across all tests. Active anterior rhinomanometry improved for Inspiratory Resistance in 26 patients (70%) and for Expiratory Resistance for 27 patients (73%). Moreover, we found that KOS group presented a better improvement statistically significant for the QoL questionnaries, respect the control group. 1.4. Conclusion: KOS treatment is a safe and mini-invasive procedure for the treatment of NAR symptoms, well accepted from patients and with a promising improvement of QoL, better than conventional medical therapies.
