Abstract
PURPOSE : CO₂laser emits energy in the mid portion of the infrared spectrum at a wavelength of 10,600nm. The CO₂laser is the workhorse laser in the treatment of cutaneous disease With water as the chromophore (light-absorbing compound), CO₂laser light is highly absorbed in biologic tissue in which water comprises between 75-90%. The CO₂laser is superficially absorbed by tissue water, with little scatter, limiting penetration into the skin to less than 0.1 mm. The beam can be delivered with a large spot size by using silk touch(TM)-computerized scanner and with little thermal damage to the tissues by using superpulsed mode recently. The purpose of this study is to evaluate the variety of cutaneous diseases treated by CO₂laser and the therapeutic effects of the CO₂laser on various skin diseases. MATERIALS AND METHODS : 459 cases of various skin diseases treated by CO₂laser between 1996 and 1998 were subjected to detailed analysis. The CO₂laser is candela laser system (U.S.A) Model 20C. The laser produces power output that ranges from 0 to 30 W of continous wave and from 0.5 to 7.0 W of superpulsed mode. The effectiveness of treatment was measured into 4 groups-excellent, good, fair, poor by estimating the clinical improvement with initial image of photograph. RESULTS : 1. In 459 cases of various skin diseases treated by CO₂laser the case of pigmented nevus (118), wart (80), lentigo (65) and acne scar (42) comprise the large portion of patient compositon. 2. The excellent and good response above 50% of patient was observed in most of the cutaneous diseases. Especially in pigmented nevus, wart, acne scar and xanthelasima palpebrum the excellent and' good response was observed above 90% of patient. CONCLUSION : The CO₂laser is actually used in treatment for wide ranges of cutaneous disorders such as pigmented nevus, wart, acne scar and lentigo even including basal cell carcinoma and hailey-hailey disease. The CO₂laser with silk touch(TM) and superpulse mode is a very effective modality for the various skin disorders such as pigmented nevus, wart, acne scar and lentigo.
