METHOD FOR A ONE-STAGE MAMMARY GLAND RECONSTRUCTION AFTER SUBCUTANEOUS RADICAL MASTECTOMY USING A POLYURETHANE IMPLANT PLACED PREPECTORALLY Russian patent published in 2020 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to oncology. Thickness of excised skin and subcutaneous fat should be more than 1.5 cm, preoperative marking is applied to skin according to figure 1: first, median line is applied from middle of clavicle through nipple and middle of lower slope, marking the submammary fold, marking the mammary gland as a reference point for performing the subcutaneous mastectomy, then in the parasternal area in the craniocaudal direction the medial meridian is applied, and the lateral meridian is drawn along the anterior axillary line, location of skin incision is made along lower edge of areola, delineating semicircle from point A to point B, dividing areola in half, and further from point B to point B is drawn horizontal line with size of 5–6 cm towards anterior axillary line, then according to the specified marking, an skin incision is made and gland tissue is subcutaneously removed, covering tissues are separated, glandular tissue is separated from greater pectoral muscle and removed, wherein the integrity of the greater pectoral muscle without disturbing, further into the prepared skin-muscular bed on the greater pectoral muscle, without mobilizing the latter, silicone implant with polyurethane coating of appropriate size and shape is installed without using additional methods of implant covering, the latter is located only under skin and subcutaneous fat, then separate sutures are used to close subcutaneous fat and skin with an intradermal suture.

EFFECT: method enables avoiding the pectoral muscle injury, reducing the operation time and volume, reducing blood loss, preserving the pectoral muscle functionality, ensure good fixation on the tissues of the anterior chest wall, which prevents the implant rotation, reduce the risk of capsular contracture and reduce the hospital bed-days; proposed operation is less traumatic and simpler technically.
