Cryotherapy for a runny nose

Chronic runny nose, medically known as rhinorrhoea, can be an incredibly frustrating condition that impacts daily life. It may stem from various causes, including allergic rhinitis, non-allergic rhinitis or conditions like chronic sinusitis. Cryotherapy, a minimally invasive treatment, has emerged as an effective option for addressing this issue, particularly when traditional treatments fail to provide relief.

What is cryotherapy for a runny nose?
Cryotherapy involves the application of controlled cold temperatures to specific areas within the nasal passages. In the case of rhinorrhoea, cryotherapy targets the posterior nasal nerve (PNN), a key contributor to the overproduction of mucus. By freezing the PNN, the therapy disrupts the nerve signals that trigger excessive mucus production, offering long-lasting relief.
Who is cryotherapy suitable for?
ENT specialists may recommend cryotherapy for patients with symptoms of a runny nose, blocked nose or post nasal drip. This may be caused by conditions such as::
- Chronic rhinorrhoea that does not respond to medications like antihistamines or nasal sprays.
- Post nasal drip – mucus running down the back of your nose
- Allergic rhinitis (Hayfever) that isn't responsive to medications.
- Non-allergic rhinitis where triggers such as temperature changes cause a runny or blocked nose.
- Mixed rhinitis, a combination of allergic and non-allergic factors.

What does the procedure involve?
Cryotherapy for rhinorrhoea is typically performed in an outpatient setting by an ENT specialist. Here’s what patients can expect:
- Preparation: A local anaesthetic is applied to numb the nasal cavity, ensuring patient comfort during the procedure.
- Cryotherapy application: Using a small cryotherapy probe, the ENT specialist targets the PNN at the back of the nasal cavity. The probe freezes the nerve for a few seconds, reducing its ability to send signals that cause excess mucus production.
- Recovery: The procedure is quick, usually lasting around 20 minutes, and patients can often return home the same day.

Benefits of cryotherapy for rhinorrhoea
Cryotherapy offers several advantages over traditional treatments:
- Minimally invasive: No incisions or significant downtime are required.
- Long-lasting relief: Many patients experience improvement in symptoms for up to a year or longer.
- Safe: The procedure carries a low risk of side effects, with most patients reporting only minimal discomfort and mild nasal congestion which resolves within days.
- Quick recovery: Patients can typically resume normal activities within 24 hours.
Are there any risks or side effects?
Cryotherapy is generally well-tolerated, but some patients may experience minor side effects, including:
- Headaches;
- Facial discomfort;
- Nose bleeds;
- Nasal dryness;
- Nasal congestion;
- Infection;
- Changes in taste;
- Ear blockage;
- Palatal numbness.
For individuals struggling with chronic rhinorrhoea, a blocked nose or post nasal drip, cryotherapy could offer an effective, minimally invasive solution if medication has not worked for you.
If you're considering this treatment, consult a qualified ENT specialist to explore your options.
