| Abstract: | On the basis of experimental studies conducted on 535 albino Wistar rats and clinical observations over 125 patients, and from complex appraisal of morphological, biochemical, and tensiometric data the conclusion is drawn that optimal operative cutting of tissues is achieved by means of far infrared carbon dioxide laser beam with a wavelength of 10.6 microns. Comparison of these characteristics showed the strength of the postoperative scar to be much less in intraoperative tissue cutting with a steel scalpel or high-energy beam of an AIG laser with a wavelength of 1.06 microns. Low-intensity laser radiation increased the strength of the postoperative scar in the early periods in all groups. Tissue cutting with a high-energy carbon dioxide laser beam with a wavelength of 10.6 microns in combination with pre- and postoperative exposure of the zone of the incision to low-intensity 0.89 micron wavelength laser beam considerably increases the strength of the postoperative scar and is the method of choice in the treatment of aseptic wounds. |
