This clinical trial aims to learn if laser posterior nasal nerve neurolysis can treat chronic rhinitis in adults. It will also learn about the safety of laser posterior nasal nerve neurolysis. The main questions it aims to answer are:
1. Does laser posterior nasal nerve neurolysis improve chronic rhinitis symptoms?
2. What side-effects or complications do participants have after laser posterior nasal nerve neurolysis?
Researchers will compare laser posterior nasal nerve neurolysis to a placebo(a sham surgery with the same device and sound to see if laser posterior nasal nerve neurolysis works to treat chronic rhinitis.
Participants will
1. Receive laser posterior nasal nerve neurolysis in the office as local anesthesia surgery.
2. Visit the clinic in the first week, first month, and 3rd months after the surgery.
3. Record their symptom scores before the surgery and during each follow-up visit.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Age between 18 and 65 years old
* Chronic rhinitis symptoms for at least 6 months that have not responded effectively to medication (should include at least Intranasal corticosteroid (ICS) combined with intermittent use of oral antihistamine and, as needed, combination nasal spray) or where medication has not provided sustained improvement
* Total rTNSS ≥ 5 with Moderate to severe rhinorrhea symptoms (24-hour reflective Total Nasal Symptom Score \[rTNSS\] rhinorrhea score of 2-3) and mild to severe nasal congestion symptoms (rTNSS nasal congestion score of 1-3)
* All enrolled patients routinely undergo endonasal endoscopic examination, or have had a sinus CT within the past month confirming no significant rhinosinusitis."
Exclusion Criteria:
* Obstructive anatomical abnormalities limiting access to posterior nasal passages
* Nasal anatomical changes due to previous sinus or nasal surgery or injury
* Ongoing nasal or sinus infection
* History of severe dry eye, chronic epistaxis, rhinitis medicamentosa, or head and neck radiotherapy
* Self-reported history of bleeding tendency
* Current use of anticoagulants with inability to discontinue
* Previous chronic rhinitis surgery
* History of poor wound healing after head, neck, or throat surgery
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Change in chronic rhinitis score
Timeframe: From the date of randomization and every three months after intervention is performed on 3, 6, 9, and 12 months post intervention.
