About the Procedure
Posterior nasal nerve ablation is a minimally invasive treatment intended to reduce the overactive nerve signals that contribute to chronic runny nose (rhinorrhea) and congestion. Depending on the device used, cold (cryotherapy) or radiofrequency energy is applied to nerve branches at the back of the nasal cavity.
It is offered only after chronic rhinitis is confirmed and other causes, such as sinus disease, significant structural obstruction, or a cerebrospinal fluid leak, have been considered and excluded. The goal is to reduce bothersome symptoms, not to eliminate normal nasal secretions.
At Norelle Health, posterior nasal nerve ablation is considered as one option within a broader plan that also includes medical and allergy treatment. Whether it is suitable depends on the type and severity of symptoms, the response to prior treatment, and the findings on nasal endoscopy.
Who may consider it
Posterior nasal nerve ablation may be considered for patients with:
- Persistent runny nose or postnasal drainage
- Congestion from allergic, nonallergic, or mixed rhinitis
- Symptoms not adequately controlled with appropriate medication
- A diagnosis confirmed by examination
- A preference for an office-based option when suitable
It targets nerve-mediated symptoms and is one part of an overall plan rather than a replacement for diagnosis and medical care.
Who may need another approach
Another approach may be more appropriate when there is:
- An untreated sinus infection or nasal polyps
- Major septal or nasal valve obstruction
- A suspected cerebrospinal fluid leak
- Unexplained one-sided symptoms
- A condition better treated with allergy therapy or a medication adjustment
- A contraindication to the selected device
Evaluation helps identify these situations so that the right treatment is chosen.

How evaluation should work
Evaluation documents the type and severity of symptoms, triggers, the response to medication, and the relevant anatomy. Nasal endoscopy helps identify other disease and confirm access to the treatment area.
The clinician explains the device, what is known about its benefits and limits, the alternatives, and the expected onset of improvement. Insurance coverage varies and is not promised.
How it is performed
After topical or local anesthesia, the device is positioned at treatment sites in the posterior nasal cavity, and cold or radiofrequency energy is applied to the nerve branches. Multiple sites may be treated depending on the technique.
Many treatments can be performed in the office. The exact visit length and any restrictions depend on the specific approach and your individual situation.
Risks and alternatives
Possible risks include nosebleed, pain, crusting or dryness, temporary numbness or altered sensation depending on the device, incomplete or temporary benefit, and the need for additional treatment.
Alternatives include intranasal medical therapy, allergy management, and, for uncommon selected cases of severe refractory symptoms, vidian neurectomy, which is more invasive and has a different risk profile.
