Abstract
In order to apply high power semiconductor laser scalpel in oral and maxillofacial surgery, we studied the wound healing process on abdominal skin of five japanese white rabbits, being incised by contact high power semicondactor laser scalpels (10W, 15W, 20W). We compared and discussed the results with those obtained when using the referetial Nd: YAG laser scalpel (10W, 15W, 20W) and electric scalpel (75W, 100W).
Optically no bleeding was observed when using a high power semicandactor laser scalpel and Nd: YAG laser scalpel, and partial bleeding spots were observed when using an electric scalpel. The wound healing process using the hish power semicondactor laser scalpel and Nd-YAG laser scalpel were almost same in recovery and were better than when using an electric scalpel. Spreding tendency of the surgical wound was observed when using an electric scalpel. Histologically, normal wound healing was observed when using any scalpels.
These experimental results revealed that high power semiconductor laser scalpel had effective prevention for post-incisional bleeding and no organic effect on the circumferential tissues as a result of the irradiation.
