RFA is primarily used for the treatment of skin lesions, tumors, and other benign or pre-cancerous growths. It is a minimally invasive technique that utilizes high-frequency electrical currents to destroy targeted tissues.

Here’s how the procedure generally works in dermatology:

1. Preparation: The patient’s skin is cleaned and a local anesthetic is applied to numb the area surrounding the targeted lesion. This ensures that the patient remains comfortable during the procedure.

2. Insertion of the RFA probe: The dermatologist will insert a thin, needle-like probe or electrode directly into or near the skin lesion.

3. Radiofrequency application: Once the probe is properly positioned, the device delivers high-frequency electrical currents to the lesion or tissue. These currents generate heat, which causes coagulation (clotting) of the proteins in the cells, ultimately destroying the target tissue.

4. Monitoring and control: Throughout the procedure, the dermatologist will carefully monitor the process to ensure that the appropriate amount of tissue is destroyed without damaging surrounding healthy tissue.

5. Post-procedure care: After the procedure is completed, the patient may experience some discomfort or minor side effects like redness and swelling. Generally, RFA is well-tolerated, and the recovery period is relatively short.

6. Follow-up: Depending on the nature of the condition being treated, follow-up appointments may be scheduled to assess the effectiveness of the treatment and monitor for any signs of recurrence.

RFA is considered a safe and effective treatment option for various dermatological conditions, and it often provides good cosmetic outcomes compared to traditional surgical excision methods.
