What is Electrosurgery?

Electrosurgery is a common surgical technique employed in Dermatology that uses high-frequency electrical current to remove soft tissues, such as benign skin growths (e.g. warts or skin tags) or pre-cancerous lesions [1]. The heat that is generated by the current is used to destroy the target lesion. This technique can be used to control bleeding as well, other than performing surgical procedures such as cutting or coagulating tissues.

What does Electrosurgery treat?

Dermatologists may use electrosurgery to treat:

Seborrheic keratosis – Seborrheic keratosis, also known as an “age spot”, is a benign skin growth which has a dark, bumpy and rough appearance. They are typically non-cancerous, but patients may want to remove them for aesthetic concerns.
Viral warts – Warts caused by infections such as human papillomavirus (HPV) can be removed using electrosurgery techniques.
Acrochordons/skin tags – Skin tags are typically benign growth on the skin, most common in areas where the skin rubs against each other. Skin tags can cause discomfort depending on the size and location.
Rhinophyma – Rhinophyma is a skin condition which is characterised by the overgrowth of connective tissues on the nose, this causes the nose to look red, bulbous, and even bumpy.
Actinic keratosis – Actinic keratosis is characterised by a rough, scaly, and bumpy appearance of the skin. Actinic keratosis lesions are caused by sun exposure and UV damage, hence they may appear in areas such as the back of the hands, nape of the neck, ears, nose, and scalp. Actinic keratosis may develop into squamous cell carcinoma and hence early treatment is important.
Angiomas – Angiomas are growth of blood vessels, common types of angioma are cherry angiomas and spider angiomas. Electrosurgery is an attractive option to remove angiomas because it is also able to stop bleeding.

When is Electrosurgery recommended?

Electrosurgery is a common technique used in dermatologic practices, as it effectively removes superficial skin lesions or growths with minimal bleeding. However, it is important to consult a dermatologist to identify which skin growths and lesions can be removed or treated safely with electrosurgery. Certain skin conditions, especially skin cancers such as melanoma, may require other treatment methods e.g. biopsy and excisions

Who cannot undergo electrosurgery?

Due to the nature of the procedure, patients with implantable electronic devices (IEDs), such as pacemakers or implantable cardioverter defibrillators may not be suitable to undergo certain types of electrosurgery. Discussions with your cardiologist may be required.

Frequently Asked Questions

Is electrosurgery painful?

You may feel mild heat sensations or slight pressure, but an electrosurgery procedure is generally well-tolerated. It is performed under local or general anaesthesia to ensure your comfort.

Is there a risk of electrocution with electrosurgery?

During the process, there will be a grounding pad used to mitigate the risk.

How long does it take to recover from an electrosurgery procedure?

Recovery time generally depends on the area that’s being treated and the complexity of the procedure. The skin will typically scab over and healing can take a few days to a few weeks.

Does electrosurgery leave scars?

Electrosurgery typically leaves behind minimal scarring. Proper post-procedure care can also minimise your risk of scarring.
