INTRODUCTION : As there are about 5-10% of all skin diseases amount to benign skin lesions and other cosmetically disabling conditions, amenable to laser therapy, it is decided to find out the effect of CO2 laser in the treatment from the patient’s point of view regarding better look cosmetically and psychologically. AIM AND OBJECTIVES : 1. To asses the effect of CO2 Laser in benign skin conditions. 2. To observe the side-effects of CO2 Laser while and after treatment. MATERIALS : A prospective analytical study was conducted in the department of dermatology, government stanley medical college and hospital, chennai, tamilnadu for a period of twenty five months from august 2004 to september 2006. Sixty cases were serially selected from the OPD who fulfill the inclusion criteria. This includes approximately 20% of failure expected either in the response to treatment and follow up. Selected cases were included after fulfilling the criteria, serially numbered, written consent obtained, proforma filled and filed. They were subjected to laser treatment, the mode, the power, the frequency and the time of laser application calculated depending on the type and depth of lesion, site of involvement and patient’s skin type. All the patients were treated under local anaesthesia ( 2% Xylocaine). Immediate side-effects were noted if any and the patients were followed up 1st week, 2nd week, 1st month, 2nd month, 6th month and 12th month. During the post treatment period the patients were treated with topical antibiotics ( 1% Silver Sulphadiazine cream) and topical sunscreen like Zinc oxide cream. Procedures were repeated at variable intervals depending upon the response and the results were analysed accordingly. INCLUSION CRITERIA : 1.Uncomplicated benign skin and vascular conditions [Epidermal nevus, Intradermal naevus, Naevus sebaceous of jadassohn, Lentigines, Lymphangioma circumscriptum ,Angiokeratoma, Benign appendageal tumors, Angiofibroma, Xanthelasma, etc]. 2. Tattoo, 3. Hypertrophic scar, 4. Patients who gave written consent for clinical photos and treatment. EXCLUSION CRITERIA: 1. Patients who were not willing to give written consent, 2. Secondary infections of the lesion to be treated. CONCLUSION : 1. In our study, CO2 laser gave excellent results in conditions like Actinic cheilitis, Intradermal nevus, Verrucous epidermal nevus, Xanthelasma palpebrarum and Syringoma. 2. In our study, CO2 laser gave good results in conditions like Angiofibroma, Tattoo removal, Hypertrophic scar and Angiokeratoma of Fordyce. 3. In conditions like, Multiple Trichoepithelioma, Nevus of Ota and Colloid milium, there was only minimal improvement. Perhaps better results would have been obtained with more treatment exposures and better patient compliance. 4. In conditions like, Keloid, Acne keloidalis nuchae and Lymphangioma circumscriptum, there was high incidence of recurrences even after adequate treatment sessions. 5. The conditions included in our study should be followed up over a long period to watch out for any recurrences following CO2 laser treatment. 6. The side effects like hypopigmentation, hyperpigmentation and mild atrophy would resolve over a period of time. 7. Keloidal scars were developed in two cases following the treatment of verrucous epidermal nevus and tattoo removal which may be due to the inherent tendency of the patients. 8. CO2 laser offers a well tolerated treatment modality without compromising the cosmetic aspects. 9. The CO2 laser is a good method of treatment for various benign skin lesions, especially where precise tissue ablation and concomitant haemostasis are desired.
