Primary outcomePrimary: Nasal Congestion as Assessed by the Peak Nasal Inspiratory Flow (PNIF) — 90 Liters Per Minute
Summary
The purpose of this study is to assess the effectiveness of radiofrequency ablation (RFA) of the posterior nasal nerve (PNN) in chronic rhinitis (CR) patients by comparing patient reflective total nasal symptom score (rTNSS) and nasal obstruction symptom evaluation (NOSE) , peak nasal inspiratory flow (PNIF) , and levels of Type 2 cytokines pre- and post-procedure.
