| Abstract: | In this study in 90 rats the measured rate of healing, pO2 in sites of postoperative scar and histological specimen of identical excisional wounds produced by CO2-laser, scalpel and combination are compared. The data of healing laser wounds via scalpel ones show slow laser wound healing. We explain, this by inhibition of the inflammation phase due to diminishing macrophages migration into the wound. pO2 data in postoperative scar after laser and scalpel wounds show that laser thermal alteration does not influence CO2 regimen in the scar. |
