Abstract

Lasers have introduced new therapeutic modalities in medicine. A wide variety of lasers provides plastic surgeon with variable treatment options that were not available previously.
The 1062㎚ Nd;YAG contact laser system was used to treat 26 patients (34 cases) during period of March 1997 to July 1998. We used different setting of power rate in continuous wave mode for each purpose. The power setting of 1-2W was used for the laserbrasion because of good melting and coagulation effect. A 6-8W was selected for flap dissection and incision because of good cutting ability and excellent hemostasis. The handpiece was equipped with a frosted end contact laser scalpel made of synthetic sapphire crystal. This scalpel has a wavelength conversion infrared absorbing surface treatment on it’s distal end ,which limits the depth of penetration to less than 0.5㎜ and increases the temperature gradient of the tissue.
When we used Nd;YAG contact laser, the advantage were as the follows. In laserbrasion by the Nd;YAG contact laser, smokeless and bloodless field was possible. And penetration depth can be accurately controlled. It was easy and quick technique, so postoperative discomfort was minimal. In flap dissection and incision, penetration depth can be accurately controlled and there was-minimized bleeding, so visualization was excellent. Nd;YAG contact laser has good cutting ability with only a little heat damage of adjacent tissue, so precise dissection can be possible. The contact laser technique combines the advantages of both the scalpel and electrocautery.
In conclusion, Nd;YAG contact laser system produces clinically favorable therapeutic effects in patients with epidermal or upper dermal lesions as well as flap dissection and incision.
