Abstract:

For the last 13 years we have been using the CO2 laser ray in plastic surgery, indicating it strictly in cases of restorative surgery of cavernous hemangiomas and eventually in benign dermatologic lesions. With the advent of new laser technologies, its indication extended to the resurfacing field, where results depend on patient selectivity. In our experience, we noticed that the CO2 laser rays had poor results in attempts to remove tattooing and in incisions of skin and mucosa. Four years ago, we experimented with the radiofrequency equipment, whose mechanism of action in the tissues is very similar to that of the CO2 laser rays (cellular volatilization). Following experimental studies in rats and human skin, we began to employ radiosugery in daily clinical practice.
