[Fractional photo-thermolysis by laser Fraxel as an adjuvant for facial surgical rejuvenation].

The fractional resurfacing (Fraxel laser) is a new procedure for facial and extrafacial rejuvenation. His claim is obtain a great efficacy on wrinkles, close to those of the CO(2) and erbium lasers, but without their risks and long lasting down time. We use a scanner, able to create multiple (around 2000 to 3000/cm(2)) 70-150 microns diameter microthermal zones surrounded by islands of viable tissue. The reepithelialization is complete in a day, but there is a collagen denaturization in the dermis, between 300-750 microns like after a traditional resurfacing. At each session, around 25% of the dermis are treated. 4 treatments are performed with a 1 to 2 weeks interval. We report our comprehensive results since we began in December 2004. At the time of the abstract, 600 sessions were performed (150 Patients). A visible reduction of wrinkles is observed anytime, with improvement of the texture of the skin, and in the same time, a dramatic improvement of the pigmented lesions. About tolerance, no severe side effects or dyschromia were noticed. We observed two case of limited erosion, (one of the first patients) due to a practical problem (bulk heating). The average erythema duration is 2 days. On the face, a 2-4 days edema occurs in many of the patients. Fraxel laser treatment is not designed as a substitute for surgical skin tightening such as facelift. Therefore, the fractional resurfacing is safe and effective for a visible reduction of wrinkles and appears as a very interesting treatment in association with face lift to rejuvenate the face.
