Effects of Radiofrequency Ablation of Posterior Nasal Nerves on Inflammatory Cytokines, Peak Nasal Inspiratory Flow, and Nasal Blood Flow in Patients With Chronic Rhinitis

March 18, 2025 updated by: David Z. Allen, The University of Texas Health Science Center, Houston
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.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Inclusion Criteria:

  • chronic rhinitis symptoms for at least 6 months (rhinorrhea, congestion, post-nasal drip)
  • poor response to medical management that was attempted for at least 4 weeks
  • a rTNSS score ≥6, as well as ≥2 for rhinorrhea, and ≥1 for congestion.

Exclusion Criteria:

  • active sinusitis
  • rhinitis medicamentosa

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Radiofrequency ablation (RFA)
Device: Radiofrequency ablation (RFA)
The NEUROMARK device is an in-office, disposable bipolar RFA device with a treatment tip consisting of micro electrodes which delivers RF energy while monitoring appropriate tissue contact to maximize delivery to posterior nasal nerve and its variable branching. After topical anesthesia consisting of oxymetazoline and 1% lido followed by 4% lidocaine, the device will be placed in the posterior inferior turbinate under endoscopic visualization. The device will be activated per manufacturer's instructions

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Nasal Congestion as Assessed by the Peak Nasal Inspiratory Flow (PNIF)
Time Frame: Baseline
PNIF is used to assess nasal air flow during maximal inspiration, and is reported in liters per minute.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Nasal Congestion as Assessed by the Reflective Total Nasal Symptom Score (rTNSS)
Time Frame: Baseline
This is a 4 item questionnaire and each is scored from 0(none) to 3(severe). The sum of the 4 times were added to generate a scale from 0 to 12, a higher number indicating more congestion
