Study the Applications of CO2 Laser in Medicine

Abstract

Carbon dioxide (CO2) laser ablative fractional resurfacing produces skin damage, with removal of the epidermis and variable portions of the dermis as well as associated residual heating resulting in new collagen formation and skin tightening. The nonresurfaced epidermis helps tissue to heal rapidly; with short-term postoperative erythemaThe results for 8 patients after a single session of a fractional CO₂ resur- facing mode were studied. The treatments it included traces of burns, traces of surgeries, traces of wounds, open pores, fibrosis and acne scars. The patients had skin prototypes 2 to 4 and wrinkle degrees 1 to 3The histologic effects, efficacy, and treatment safety in various clinical conditions and for dif ferent phototypes are discussed. The CO2 laser for fractional treatment is used in super-pulse mode. The beam is split by a lens into several microbeams, and super-pulse repetition is limited by the pulse width. The laser needs a power adaptation to meet the set fluence per microbeam. Laser pulsing can operate repeatedly on the same spot or be moved randomly over the skin, using several passes to achieve a desired residual thermal effect. Low, medium, and high settings are preprogrammed in the device, and they indicate the strength of resurfacing. A single treatment was given with the patient under topical anesthesia. Howeverthe anesthesia was injected on areas of scar or applied as a cream over the skin.
