The UltraPulseTM carbon dioxide laser (Coherent, Inc., Palo Alto, California) was used in skin ablation to treated superficial skin tumors, fine wrinkles, and as a laser scalpel for incisions and excisions. Thermal damage using this laser was much less than with traditional continuous wave and normal pulsed modalities. An animal model was employed to measure the histological thermal damage of various laser irradiations.
The results with the UltraPulseTMproved it to be an effective treatment device with minimum thermal damage and no complications. Furthermore, laser ablation depth was controlled by the number of laser passes. In some cases, post-operative hyperpigmentation developed, especially near the zygomatic prominence area, but pigmentation returned to normal after the application of 4% hydroquinone with 0.025% Retin-ATM emollient cream (Shantel Irradiance, Los Angeles, California) for several weeks.
The UltraPulseTM is a useful and effective device for plastic and aesthetic surgery.
