The procedure can be performed in an outpatient setting, with medical staff beginning by injecting the patient with a local anesthetic. Once the nasal cavity is numb, they will insert an endoscope with a bulb-like device on the end containing liquid nitrogen into the nose. The nitrogen is then released onto the desired area to freeze the nerves. The whole procedure only takes around 90 seconds to complete, after which point the patient is given pain relief medication alongside anti-inflammatories. They are then monitored for around 30 minutes before being allowed to return home, where any symptoms usually disappear within 24 hours. Initially, patients may experience a blocked nose, but this will improve once the wounds heal.

• Patients usually see an improvement to their original symptoms around 7–30 days after undergoing the procedure, with medical studies finding that 80% of patients see an improvement lasting up to 1 year following treatment.
