10 patients (6 females, 4 males) with adenoma sebaceum in tuberous sclerosis were treated by CO2 laser in Military Central Hospital 108 during period 1995 - 1998. The outcomes of treatment were excellent with almost complete resolution of all facial lesions without scar or recurrence over average 32-month following. The laser procedure provided high precision and efficiency without bleeding.

This study was performed on the rabbit skin using CO2laser. Rabbits were divided into 6 batches to receive CO2 laser with settings 5w to 8w, 1 - 2mm spots and 0.1s pulse to continuous waves. The results showed that thermal damages varied from 207m in 8A batches (8w, 1mm, 0.1s) to 817m in 5D batches (5w, 2mm, CW). The crater of the laser impact site in 8w, 1mm, 0.1s batch is cleaner and sharper then that in other batches

The port-wine stain has always been a difficult lesion to treat cosmetically. Skin biopsoes prior to treatment port-wine stains and at 11- 42 months after CO2 laser treatment of port-wine stain were taken in 6 patients of both sexes. Histology after CO2 laser surgery in successfully treated lesions is remarkable for a few small-caliber dilated vessels with relativelly free of erythrocytes. The histology after CO2 laser surgery also revealed a large amount of collagen deposited and a few appendageal structures in the dermis.

78 patients with Port wine stains (PWS) were treated by surgical method. The result showed that surgery is useful and effective. However, surgical scars are common and the skin grafts have more dark color than surrounding (if the skin grafts were required). So it must be very carefully in making a decision for surgery and choose a suitable method for each patient. The surgery is attempted to close local skin. And in case of the skin graft is required, it is better to take a full thickness skin graft in areas near to the face and neck.

The study was conducted on 84 patients with Post-wine stain from January 1995 to April 1999 in the Army Central Hospital 108. This genital condition develops laterally on skin of face and neck and in upper and middle areas of face. Lesions were characterized by colour, prominency, lump, Waner grade and ligh-colour changeability when stretching skin. Usually, this condition is more severe in adult patients and if the lesion occurred on upper lip, the condition were more complicated with lip enlargement and involved in mucous membrane.

14 patients with xanthelasma palperbraum of the eyelids have been treated with the CO2 laser. The lipomatous yellow plaque are accurately photovaporized in a bloodless field until the lesion is totally eradicated. The operation with the CO2 laser does not depend on a shape, size, position of the lesion. Satisfactory cosmetic results were achived in 13 of 14 patients without significant scarring.
