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

9. juli 2026 opdateret af: Carol Yan, University of California, San Diego

Radiofrequency Ablation (RhinAer, Neuromark) vs. Cryoablation (ClariFix) of the Posterior Nasal Nerve for Chronic Rhinitis: A Randomized Controlled Trial

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)

Detaljeret beskrivelse

Chronic rhinitis (non-allergic/vasomotor rhinitis) affects an estimated 14 million Americans and is characterized by nasal inflammation in the absence of infectious or allergic triggers. When medical management fails, patients may pursue procedural intervention to ablate the posterior nasal nerves. Currently available FDA-cleared standard-of-care options include in-office radiofrequency ablation (RhinAer, Neuromark) and cryotherapy (ClariFix). Despite the availability of these modalities, comparative effectiveness data are lacking. This randomized controlled trial will enroll adult patients and randomly assign them to one of the three treatment arms to compare symptom reduction and durability of response across the three procedures.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Aktiv komparator: RhinAer
RhinAer is a radiofrequency ablation procedure for chronic rhinitis. This in-office procedure applies temperature-controlled radiofrequency energy to ablate the overactive posterior nasal nerve.
Enhed: RhinAer
RhinAer is an in-office radiofrequency ablation device that delivers targeted thermal energy to the posterior nasal nerve along the lateral nasal wall. The procedure is performed under local anesthesia without the need for general anesthesia or sedation, and aims to reduce parasympathetic nerve signaling to decrease rhinorrhea, postnasal drip, and nasal congestion in patients with chronic rhinitis.
Aktiv komparator: Neuromark
Neuromark is a radiofrequency ablation procedure for chronic rhinitis. This in-office procedure applies temperature-controlled radiofrequency energy to ablate the overactive posterior nasal nerve.
Enhed: Neuromark
Neuromark is an in-office radiofrequency ablation device that delivers targeted thermal energy to the posterior nasal nerve along the lateral nasal wall. The procedure is performed under local anesthesia without the need for general anesthesia or sedation, and aims to reduce parasympathetic nerve signaling to decrease rhinorrhea, postnasal drip, and nasal congestion in patients with chronic rhinitis.
Aktiv komparator: ClariFix
ClariFix is a cryoablation procedure for chronic rhinitis. This in-office procedure applies freezing (cryotherapy) to ablate the overactive posterior nasal nerve.
Enhed: Clarifix
ClariFix is an in-office cryoablation device that applies freezing (cold thermal) energy to the posterior nasal nerve in the posterior nasal cavity. The procedure is performed under local anesthesia without the need for general anesthesia or sedation, and aims to reduce parasympathetic nerve signaling to decrease rhinorrhea, postnasal drip, and nasal congestion in patients with chronic rhinitis.

Foranstaltningsbeskrivelse
Tidsramme
Sino-Nasal Outcome Test-22 (SNOT-22)
Tidsramme: SNOT-22 will be administered at baseline and at 1, 3, and 6 months post-procedure.
SNOT-22 is a validated 22-item patient-reported outcome measure assessing sinonasal-specific quality of life across domains including nasal symptoms (nasal blockage, rhinorrhea, loss of smell/taste), ear and facial symptoms (ear pain, facial pressure), sleep dysfunction (difficulty falling asleep, waking up tired), and psychological and functional impairment (reduced productivity, fatigue, sadness).
SNOT-22 will be administered at baseline and at 1, 3, and 6 months post-procedure.
Total Nasal Symptom Score (TNSS)
Tidsramme: TNSS will be administered at baseline and at 1, 3, and 6 months post-procedure.
TNSS is a validated 4-item patient-reported scoring instrument measuring severity of rhinorrhea, nasal congestion, nasal itching, and sneezing.
TNSS will be administered at baseline and at 1, 3, and 6 months post-procedure.

Foranstaltningsbeskrivelse
Tidsramme
Visual Analog Scale (VAS) Patient Satisfaction
Tidsramme: VAS patient satisfaction will be administered at 1, 3, and 6 months post-procedure.
A 0-10 visual analog scale on which patients rate their overall satisfaction with the procedure and its effect on their chronic rhinitis symptoms, with higher scores indicating greater satisfaction.
VAS patient satisfaction will be administered at 1, 3, and 6 months post-procedure.
