Nasal cryotherapy is an incision-free treatment that can help patients with chronic rhinitis symptoms, such as a chronic runny nose, nasal congestion or postnasal drip, that persist despite medical management. This intranasal cryoablation can be considered for allergic or nonallergic rhinitis, including allergic rhinitis and chronic nonallergic rhinitis such as vasomotor rhinitis.
What Is Cryoablation for Rhinitis?
Cryoablation for rhinitis, also called nasal cryoablation, uses controlled cold to reduce overactive posterior nasal nerve signals that contribute to excess mucus production and swelling in chronic rhinitis, a common problem for many patients in Singapore.
Cryoablation of the sphenopalatine area targets distal posterior nasal nerve branches beneath the nasal lining in each nasal cavity. These posterior nasal nerves help control nasal secretions and blood flow. In chronic rhinitis, overactive nerves may keep the nose runny, congested or sensitive to triggers.
Unlike nasal surgery, cryoablation requires no external incision. The procedure does not remove, reshape, cauterise or reconstruct tissue, and no sample is usually sent for laboratory testing.
Cryoablation does not cure the underlying allergy in allergic rhinitis or prevent reactions to inhaled allergens. This cold therapy treats symptoms linked to overactive nerves in chronic rhinitis, so allergen avoidance, nasal medicines or immunotherapy may still be needed.
Why Is Cryoablation Done and Who May Need It?
Nasal cryotherapy may be considered for refractory chronic rhinitis when symptoms of chronic rhinitis linked to overactive nerves persist despite appropriate medical management.
Chronic rhinitis includes allergic rhinitis, nonallergic rhinitis such as vasomotor rhinitis, and mixed forms. The symptoms of chronic rhinitis include:
- A persistent watery runny nose.
- Nasal congestion or blockage.
- Postnasal drip and frequent throat clearing.
- Nasal itching, sneezing or sensitivity to smells, temperature changes, smoke or spicy food.
- Reduced quality of life when nasal symptoms affect sleep, work or daily activities.
Other causes of nonallergic rhinitis include medicine-related, hormone-related and infectious conditions, such as a nasal or sinus infection. These need different treatment and should be identified first.
Medical management of chronic rhinitis starts with trigger avoidance, saline irrigation and symptom-specific medicines. These may include intranasal steroids, an intranasal antihistamine or an anticholinergic spray for watery discharge. Allergy testing and immunotherapy may be appropriate for some people with allergic rhinitis. Your specialist will review which treatments are appropriate before considering nasal cryotherapy.
Nasal cryotherapy may be an option for vasomotor rhinitis or allergic rhinitis if medical management does not provide enough relief, causes unwanted effects or is difficult to use consistently. Some studies show that people with higher total nasal symptom scores at the start of treatment improve more, but this does not predict an individual result.
The procedure may not be suitable if symptoms are mainly caused by a severe deviated septum, large nasal polyps, or another cause of nasal obstruction. An active nasal infection, a bleeding disorder, difficulty tolerating nasal endoscopy, or certain cold-related conditions may also affect suitability.
When to See an ENT Specialist
See an ENT specialist when symptoms of chronic rhinitis persist, recur, or interfere with your quality of life despite medical management.
A specialist assessment matters for patients with chronic rhinitis because nasal obstruction and discharge can have multiple causes, and each cause requires a different treatment. Your ENT specialist may review your nasal symptoms, triggers, medicines, previous medical management and general health. Examination may include nasal endoscopy to assess the nasal mucosa. Itching inside your nose, dry or watery eyes and other ocular symptoms may suggest allergic rhinitis. Allergy tests or a CT scan may be used in selected cases, but they are not needed for everyone.
Seek earlier assessment if you have severe symptoms, one-sided symptoms, repeated nosebleeds, fever, thick or foul-smelling discharge, marked facial pain, a visible nasal mass or a significant loss of smell. These features may point to a condition that needs different care.
How to Prepare for Cryoablation for Rhinitis
Tell your ENT specialist about all prescription medicines, over-the-counter products and supplements you take. This is especially important for aspirin, anticoagulants, and other medicines that can increase bleeding. Do not stop a prescribed medicine unless the clinician who manages that specific medication advises you to. Speak to your other medical providers before proceeding with cryoablation treatment for rhinitis.
Also tell your specialist if you have:
- A current cold, sinus infection or fever.
- Frequent nosebleeds or a bleeding disorder.
- An allergy to local anaesthetic.
- Cold urticaria, cryoglobulinaemia, Raynaud disease or another unusual reaction to cold.
- Pregnancy or a significant medical condition.
Fasting is usually not required when treatment is performed under local anaesthesia alone. If sedation or general anaesthesia is planned for another reason, follow the fasting instructions the treatment team provides. Avoid smoking and vaping because they irritate the nasal lining and can delay healing.
Most patients go home the same day as the procedure. Arrange for transport if you will receive a sedative or if your specialist advises you not to drive. Ask when you can resume normal activities.
What Happens During Cryoablation for Rhinitis?
For most patients, nasal cryotherapy is performed through the nostrils under local anaesthesia in a health care provider’s office or outpatient treatment room, without a skin incision or hospital admission.
The main steps are:
- A decongestant and local anaesthetic are applied inside the nasal passages.
- A nasal endoscope inspects the nasal cavity and guides treatment.
- A slim handheld cryotherapy device is placed against the nasal lining over the distal posterior nasal nerve branches near the sphenopalatine area.
- Controlled cooling cryoablates the posterior nasal nerve region briefly on each side of the nose.
- The cryotherapy device is removed, and the nose is checked for bleeding.
You may feel pressure, a cold sensation, mild discomfort or a mild headache during or shortly after the cryotherapy treatment. General anaesthesia is not usually needed. The procedure and numbing period often take about 20 to 30 minutes, although timing varies with the device, anatomy, and treatment plan. This cryoablation treatment differs from endoscopic vidian neurectomy, a form of vidian nerve surgery that involves severing the vidian nerve. Radiofrequency ablation is another posterior nasal nerve treatment that uses heat rather than cold.
What to Expect After Surgery and Recovery Timeline
Recovery after intranasal cryotherapy is usually brief, and many patients return to normal activities the same day or the next day.
Temporary congestion, watery discharge, nasal dryness, mild bleeding, facial pressure, headache or crusting can occur. Discomfort is often manageable with simple pain relief recommended by your clinician. There is no external wound or dressing. Use saline rinses or sprays only as directed, and avoid forceful nose blowing while the treated area settles.
Your specialist may advise avoiding strenuous exercise, hot baths and activities that raise the risk of bleeding for a short period. Food and fluid restrictions are not usually needed after numbing medicine alone.
Symptom relief is not always immediate. Improvement in chronic rhinitis symptoms commonly develops over two to six weeks as the nasal lining settles. A follow-up visit allows your specialist to review healing, nasal symptoms such as postnasal drip, medication usage and quality of life. During the follow-up period, your specialist may record a total nasal symptom score alongside changes in your quality of life.
Published studies, including a randomised controlled study, show significant improvement in runny nose and congestion for many, but not all, patients with chronic rhinitis. Distal posterior nasal nerves may recover over time, and nasal symptoms may return. After reassessment, repeat treatment or another procedure may be considered, but evidence on long-term efficacy and retreatment remains limited.
Risks and Possible Complications
Most adverse effects of nasal cryotherapy are mild and temporary, while serious adverse effects or adverse events have been uncommon in published studies.
Adverse effects include:
- Temporary nasal congestion, dryness or crusting.
- Mild pain, pressure or headache.
- A small nosebleed.
- Ocular symptoms, such as watery eyes.
- Temporary numbness of the palate, teeth or upper lip.
- Brief light-headedness or faintness.
- Infection or persistent bleeding, which is uncommon.
- Little or no improvement in rhinitis symptoms.
Across published studies, adverse events such as nasal dryness and nosebleeds were generally reported in fewer than 5% of patients, although rates of pain, headache and other adverse effects varied.
Contact your ENT team promptly for bleeding that does not stop, fever, worsening facial pain or swelling, breathing difficulty, visual symptoms, severe headache, or numbness that is marked or does not improve.

Dr Barrie Tan is a Senior Consultant ENT Specialist at Gleneagles Hospital in Singapore. If cryoablation is appropriate, he can explain the expected benefits, limitations, alternatives, anaesthesia and aftercare for your circumstances.
Before treatment, ask for an itemised nasal cryotherapy cost estimate and check whether it includes consultation, nasal endoscopy, anaesthesia and follow-up. If nasal symptoms have not improved with medical management, contact Barrie Tan ENT Head & Neck Surgery, to arrange an assessment and discuss whether cryoablation, radiofrequency treatment, nasal surgery or another treatment may be suitable for you.
FAQs
Can nasal cryotherapy help with rhinitis?
Yes, nasal cryotherapy may reduce runny nose, congestion and postnasal drip in selected people with allergic, nonallergic or mixed chronic rhinitis, including vasomotor rhinitis. It is generally considered after an accurate diagnosis and an adequate trial of medical treatment. It does not remove an allergy or correct a structural blockage, so use it only when appropriate.
Is nasal ablation painful?
Nasal cryoablation is usually tolerated with local anaesthesia. You may feel pressure, cold or mild discomfort during treatment. Mild facial discomfort or headache can occur afterwards and usually settles with time and simple pain relief recommended by your clinician.
What is the best treatment for chronic rhinitis?
The best treatment depends on the cause and the symptom that affects you most. Care may include avoiding triggers, saline irrigation, nasal medicines, allergy treatment or medical or surgical management of a structural problem. Consider cryoablation when nerve-mediated runny nose or congestion persists despite appropriate nonsurgical care.
