Radiofrequency Lesioning: A Treatment for Trigeminal Neuralgia
Radiofrequency lesioning, also referred to as radiofrequency rhizotomy, is a preferred surgical option for patients with a heightened risk of complications from other surgical procedures when treating trigeminal neuralgia. Instead of addressing the root cause of the condition, radiofrequency lesioning focuses on interrupting the transmission of pain signals to the brain. During the procedure, an electrode is inserted through the cheek, generating heat and damaging the affected nerve.
What to Expect After Radiofrequency Lesioning Treatment
After undergoing radiofrequency lesioning treatment, the majority of patients experience immediate relief from pain, with about 90% reporting positive results. However, it is important to be aware of potential side effects and complications associated with this procedure.
One common side effect of radiofrequency lesioning is facial numbness. While this can be bothersome for some individuals, it is generally considered a minor issue compared to the relief it provides. Additionally, there is a relatively high recurrence rate of 40% within two to three years after the initial treatment. However, the procedure can be repeated to address recurring pain.
Like any medical procedure, there is always a risk of infection at the insertion point in the cheek. It is essential to follow proper hygiene practices and keep the area clean to minimize this risk. Some patients may also experience corneal numbness, although this is typically temporary and resolves on its own.
In rare cases, there is a possibility of excessive nerve damage. It is crucial for patients to communicate any abnormal sensations or prolonged discomfort to their healthcare provider. However, if there are no complications, most individuals can expect to resume their normal activities within a day or two after the treatment.
