A Randomized Controlled Trial Comparing Posterior Nasal Nerve Ablation Procedures for Chronic Rhinitis

The goal of this clinical trial is to learn which procedural intervention most effectively reduces symptoms of chronic rhinitis (non-allergic rhinitis) in adult patients (18 years and older). The main questions it aims to answer are: * Which procedural intervention leads to the greatest reduction in total nasal symptom scores (TNSS)? * Which procedural intervention leads to the greatest improvement in sinonasal quality of life as measured by the SNOT-22? Researchers will compare radiofrequency ablation (RhinAer or Neuromark) and cryotherapy (ClariFix) to see if there are differences in symptom reduction and durability of response across treatments. Participants will: * Be randomly assigned to one of three FDA-cleared posterior nasal nerve ablation procedures (RhinAer, Neuromark, or ClariFix) * Complete validated symptom questionnaires (TNSS and SNOT-22) before and after their procedure * Have their relevant medical records reviewed (demographics, clinical history, prior rhinitis treatments)
