Posterior nasal nerve (PNN) ablation is a procedure that can help people with chronic nasal congestion, runny nose, and other bothersome nasal symptoms. This treatment is often considered when medications or other therapies haven’t worked. By targeting specific nerves in the nose, PNN ablation aims to reduce the symptoms that come from overactive nasal glands and nerve responses. Here, we’ll explore what PNN ablation is, how it works, the benefits and risks, and what to expect during and after this chronic rhinitis treatment in Los Angeles.
What Is Posterior Nasal Nerve Ablation?
PNN ablation is a minimally invasive medical procedure that targets the posterior nasal nerve, a nerve bundle located deep within the nasal cavity. This nerve controls the nasal glands that produce mucus and plays a role in nasal congestion and irritation. When these glands become too active, they can cause symptoms like constant runny nose, stuffiness, sneezing, and other forms of nasal discomfort.
The purpose of PNN ablation is to disrupt or block the posterior nasal nerve, reducing or even stopping the signals that cause these symptoms. Doctors typically use either radiofrequency energy or cryotherapy (cold therapy) to target and deactivate the nerve. The process is designed to be quick and effective, with little downtime afterward.
Why Might You Need PNN Ablation?
PNN ablation may be recommended if you have chronic rhinitis, a condition that causes constant inflammation and irritation in the nose. Chronic rhinitis can lead to symptoms like:
- Persistent runny nose (also known as rhinorrhea)
- Nasal congestion or stuffiness
- Frequent sneezing
- Itching in the nose or throat
Many people with chronic rhinitis have already tried other treatments, like nasal sprays, antihistamines, or steroid medications, with little or no success. For these individuals, PNN ablation can offer a long-term solution that focuses on reducing symptoms directly at the nerve source.

How Does PNN Ablation Work?
During PNN ablation, a doctor uses specialized tools to access the posterior nasal nerve and deliver either heat (radiofrequency energy) or cold (cryotherapy) to the nerve tissue. This energy disrupts the nerve’s ability to send signals that lead to excessive mucus production and congestion. Here’s a closer look at the two main types of PNN ablation:
Radiofrequency Ablation
Radiofrequency ablation uses high-frequency electrical currents to generate heat. The doctor inserts a small probe through the nasal passage and places it near the posterior nasal nerve. The heat generated by the probe “ablates,” or disables, the nerve tissue. This reduces the nerve’s function and prevents it from over-activating the glands that cause nasal symptoms.
Cryotherapy
Cryotherapy, or cold therapy, works in a similar way but uses cold temperatures to freeze the nerve tissue. A small, controlled burst of cold is applied to the posterior nasal nerve, which also reduces its function. Cryotherapy can be a good option for those who may prefer an alternative to heat-based treatments.
Both methods are effective and safe, and the choice between radiofrequency and cryotherapy usually depends on the patient’s condition and the doctor’s recommendation.
The Procedure: What to Expect
PNN ablation is a relatively quick and straightforward procedure, typically done in an outpatient setting. Here’s what you can expect before, during, and after the procedure.
Preparation
Before the procedure, your doctor will review your medical history and may perform a physical examination to ensure that PNN ablation is the right choice for you. They may also ask you to avoid certain medications, like blood thinners, for a few days before the procedure to reduce the risk of bleeding.
Most people do not need general anesthesia for PNN ablation. Instead, the doctor will apply a local anesthetic to numb the nasal area, which helps make the procedure more comfortable.
During the Procedure
The doctor will insert a small probe into the nasal passage and guide it to the location of the posterior nasal nerve. Depending on the method chosen, the probe will then deliver either heat (radiofrequency) or cold (cryotherapy) to disable the nerve.
The procedure generally takes about 10-20 minutes per nostril. You may feel some pressure or a mild sensation, but the local anesthetic should prevent any significant pain.
After the Procedure
After the procedure, most patients can go home right away. You may experience mild nasal discomfort, congestion, or dryness for a few days, but these symptoms usually improve quickly. Your doctor may suggest using a saline nasal spray to keep the nasal passages moist and to speed up healing.
Recovery is typically quick, and most people can resume normal activities within a day or two. However, you may be asked to avoid strenuous exercise for a short time after the procedure to help prevent irritation.
Benefits of PNN Ablation
PNN ablation offers several benefits for people with chronic rhinitis:
Long-Term Relief from Symptoms
One of the primary advantages of PNN ablation is the long-lasting relief it provides. Because the procedure targets the nerve directly, it can significantly reduce symptoms like runny nose, congestion, and sneezing for an extended period. Many patients experience months or even years of symptom relief.
Minimally Invasive
The procedure is minimally invasive and can be done without general anesthesia. This means a shorter recovery time and fewer risks compared to more invasive nasal surgeries.
Quick Procedure and Recovery
PNN ablation is a short procedure, usually taking less than an hour, and patients often recover quickly. Most people can return to their regular activities within a day or two, making it a convenient option for those with busy schedules.

Risks and Possible Side Effects
Although PNN ablation is generally safe, it does have some risks and potential side effects. It’s important to discuss these with your doctor before deciding on the procedure. Some of the possible risks include:
Mild Nasal Discomfort or Congestion
Some patients may experience mild nasal pain, dryness, or congestion after the procedure. These symptoms are usually temporary and can be managed with saline sprays or other simple treatments.
Nosebleeds
A small number of patients may experience nosebleeds following PNN ablation. These are typically mild and go away within a few days, but it’s important to contact your doctor if you experience heavy or frequent bleeding.
Rare Risk of Infection
As with any procedure, there’s a slight risk of infection. Following your doctor’s aftercare instructions and keeping the nasal area clean can help prevent this.
Who Is a Good Candidate for PNN Ablation?
PNN ablation is typically recommended for people with chronic rhinitis who haven’t found relief through medications or other treatments. Good candidates for PNN ablation include:
- Individuals with symptoms like runny nose, congestion, and sneezing that persist for months or longer.
- Those who have tried other treatments, such as antihistamines or nasal sprays, with limited success.
- Patients who want a minimally invasive option for symptom relief.
Your doctor can help determine if PNN ablation is a good choice based on your symptoms and medical history.

Alternative Treatments
If PNN ablation isn’t right for you, there are other options for treating chronic rhinitis. These include:
- Medications: Antihistamines, decongestants, and nasal steroids can help manage symptoms in many cases.
- Allergy Treatments: If allergies are contributing to your symptoms, allergy shots or other treatments may help.
- Surgical Options: In some cases, surgery to open the nasal passages may be necessary, especially if there are structural issues causing congestion.
Final Thoughts
Posterior nasal nerve ablation is an effective option for those struggling with chronic nasal symptoms. By targeting the nerve responsible for nasal irritation, this procedure can offer long-term relief and improve your quality of life.
