Electrosurgery, also known as electrodesiccation, is an emerging and promising procedure in the treatment of rosacea. By targeting dilated blood vessels and reducing facial redness, this method presents an interesting option for those suffering from this skin condition. Read on to learn everything you need to know about this new procedure.

Electrosurgery: What are we talking about?
Electrosurgery is a surgical technique that uses the heat generated by a high-frequency electric current passing through biological tissues. It is used therapeutically to coagulate, vaporize, cut, or destroy tissues. Electrosurgery is used in various types of surgical procedures, including orthopedic surgery, reconstructive surgery, and dermatological surgery. It should be noted that electrosurgery generators typically operate within a frequency range of 200,000 kHz to 5 MHz. Sensitive tissues do not depolarize at frequencies higher than 10,000 Hz, so the application of a high frequency is crucial to avoid acute pain.
Several electrodes are necessary to perform electrosurgery. Often, the practitioner applies the active electrode to the area to be treated. The dispersive electrode is placed at another level on the patient's body to close the electrical circuit. The electric current generated in the form of an electron flow thus passes through the tissues, which act as a resistance according to their water content. This resistance allows the conversion of electrical energy into thermal energy. The increase in temperature of the tissues traversed results in their coagulation.

How does electrosurgery benefit individuals prone to rosacea?
In the context of rosacea, electrodessication causes the instant coagulation of facial blood vessels, which helps to reduce the redness characteristic of this skin condition. The telangiectasias, or dilated blood vessels, are also targeted and their diameter is reduced. The electrosurgery procedure is generally quick and only requires local anesthesia, or in some cases, no anesthesia at all. It provides the practitioner with precise control over the target tissue, which reduces the risks of bleeding and damage to surrounding tissues.
Electrosurgery is a minimally invasive procedure, subsequently allowing for a quick recovery of patients.
The number of electro-surgery sessions needed to treat rosacea varies depending on the severity of the disease and the individual's response. Generally, several sessions, spread over several weeks, are required. Electro-surgery is particularly beneficial for patients suffering from telangiectasia, the vascular form of rosacea. It is also used to treat patients with rhinophyma ranging from moderate to severe.
Electrosurgery has indeed demonstrated good efficacy in a recent clinical trial conducted on patients with moderate to severe forms of rhinophyma. In total, seven individuals aged between 40 and 69 were treated, and the results were very satisfactory for all of these patients. Electrosurgery allowed a return to their original nasal shape while maintaining a healthy state of the cartilage. Thus, patients were able to regain a certain level of comfort. As for side effects, only 3 patients exhibited minor scarring after the operation.
Rosacea and Electro Surgery: Special Precautions for Use?
Electrosurgery treatment can have side effects due to the high current it uses. This technique can particularly expose one to the risk of cartilage necrosis, a complication that is nonetheless quite rare. As for post-operative care, recommendations are tailored to each patient but generally include good skin hydration, to support healing, as well as the daily application of sun protection. This latter advice helps to prevent the risks of post-inflammatory hyperpigmentation. Finally, it should be noted that special vigilance is recommended for people with dark skin as they may exhibit pigmentation disorders following the treatment.
Electrosurgery must always be performed by a healthcare professional. When carried out at home, this treatment poses high risks of infection, bleeding, and cartilage necrosis.
