METHOD FOR THE PREVENTION OF PATHOLOGICAL SCARS OF POSTOPERATIVE SKIN WOUNDS Russian patent published in 2022 - IPC A61B18/20 A61N5/67 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to plastic surgery, dermatology, and cosmetology. Physical impact is carried out using high-intensity focused pulsed light radiation. In this case, a laser is used as a source of high-intensity focused pulsed light radiation, the active medium of which is neodymium-doped yttrium aluminum garnet, with a wavelength of 1064 nm, with a pulse duration of 650 mcs and a repetition rate of 1.5 Hz. On the 7th day after the operation, the specified laser source is exposed to the skin around the wound at an energy density of 15-20 J/cm² and a laser spot diameter of 5 mm. On the 14th day, the same laser source is exposed to the skin around the wound with a laser exposure energy density of 25-31 J/cm² and a laser radiation spot diameter of 5 mm. In case of incomplete relief of inflammation in the wound, additionally for 21 days, the laser source is exposed to the skin around the wound with an impact energy density of 36-41 J/cm² and a laser radiation spot diameter of 5 mm. In case of presence of hyperemia in the area of ​​the forming scar, additionally on the 50th day, laser exposure is performed directly on the area of ​​its formation with an impact energy density of 96-127 J/cm² and a laser radiation spot diameter of 2 mm. If there are capillaries in the treatment area, additionally on day 80, laser exposure is performed directly on this area with an impact energy density of 127-159 J/cm² and a laser radiation spot diameter of 2 mm. If there are capillaries in the treatment area, additionally on the 110th day, laser exposure is performed directly on this area with an energy density of 159-191 J/cm² and a laser spot diameter of 2 mm.

EFFECT: method allows to prevent the formation of visible scars, and therefore increases the cosmetic effect of surgical operations.
