[CO2 laser vaporization of papilloma of the conjunctiva and eyelids].

In irradiated tissue, the farinfrared CO2 laser generates high temperatures of around 400 degrees C. Thermal damage can occur at the borders of the area being treated, but there are good hemostatic properties and thermal sterilization of the irradiated tissue. Photovaporization of papillomas has been occasionally proposed to achieve thermal inactivation of papilloma viruses and reduce the recurrence rates. Seventy-five cases of recurrent squamous papilloma were vaporized with a CO2 laser and followed-up for over 2 years. Only 2 recurrences were observed (20% have been reported after surgical excision). The procedure is quick, safe, easy to perform and well accepted by the patient. Good hemostatic properties, lack of cicatrication, and excellent cosmetic results are further advantages. Histological examination may be limited by thermal tissue damage.
