METHOD OF SKIN-PRESERVING MASTECTOMY WITH RECONSTRUCTION OF DE-EPIDERMISED FATTY SKIN FLAP AND FREE TRANSPLANTATION OF NIPPLE-AREOLA COMPLEX IN PTOSIS MAMMARY GLANDS Russian patent published in 2024 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to oncology and mammary gland surgery (MG) in cancer, implying removal of MG tissue and simultaneous reconstruction. Skin is incised according to Wise marking, nipple-areola complex and MG tissue are removed, de-epidermisation of the skin-subcutaneous flap of the mammary gland is performed in the area of the lower and upper slope, in the area of the removed mammary gland a de-epidermal skin-subcutaneous flap is placed as a sandwich, wherein the blood supply of the flap is preliminary examined using the intravenous administration of indocyanine, then the flap is fixed with interrupted sutures to the greater pectoral muscle on the border of the upper quadrants, a drainage is installed in the area of the formed mammary gland, free nipple-areola complex is fixed with interrupted sutures in the area of central quadrants of mammary gland to gland skin at level of 20 cm from clavicle, skin is closed in area of mammary gland.

EFFECT: use of the proposed method in clinical practice enables: preserving a greater pectoral muscle and preserving a functional component of the muscle; to perform single-stage breast reconstruction: removing a large amount of tissue with subsequent replacement with a de-epidermised fatty skin flap without using an endoprosthesis or muscle flaps; reduce the number of postoperative complications due to the use of intravenous administration of indocyanine, and in the presence of ischemic zones in the de-epidermis dermal-subcutaneous flap, the ischemic zones are intraoperatively dissected, and as a result, the percentage of necrosis in the postoperative period is reduced.
