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:

• Chronic rhinorrhoea that does not respond to medications like antihistamines or nasal sprays.
• Non-allergic rhinitis where triggers such as strong smells or temperature changes cause a runny nose.
• Mixed rhinitis, a combination of allergic and non-allergic factors.
• Conditions where other treatments, including surgery, are not suitable or desired.

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:

1. Preparation: A local anaesthetic is applied to numb the nasal cavity, ensuring patient comfort during the procedure.
2. 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.
3. 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 mild nasal congestion or crusting, 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:

• Temporary nasal congestion or dryness.
• Mild discomfort or a sensation of pressure during or after the procedure.
• Rarely, changes in nasal sensitivity or temporary numbness.

For individuals struggling with chronic rhinorrhoea, cryotherapy offers an effective, minimally invasive solution. ENT specialists can evaluate the underlying causes of your symptoms and determine if this treatment is appropriate for you. By targeting the source of the problem - the posterior nasal nerve - cryotherapy can significantly improve quality of life, reducing the impact of a runny nose on daily activities. If you're considering this treatment, consult a qualified ENT specialist to explore your options.
