METHOD OF ONE-STAGE BREAST RECONSTRUCTION IN CANCER USING AN ALLOIMPLANT BASED ON A DURA MATER AND A SILICONE ENDOPROSTHESIS Russian patent published in 2019 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to reconstructive plastic surgery of mammary gland. Greater pectoral muscle is mobilized by cutting off the lower edge of its attachment, laterally to the level corresponding to 9 o'clock on the clock face. Lower-lateral part of the greater pectoral muscle is separated from the anterior thoracic wall and a sub-pectoral pocket is formed by electrodissection to labeled levels along the perimeter of the formed gland. After the sub-pectoral pocket is created, a human dura mater (DM) membrane is prepared. Formed DM is laid on the lower breast reconstruction zone corresponding to the lower breast slope, DM edge is anchored with atraumatic suture to free edge of great pectoral muscle. Pocket width is selected to select a silicone endoprosthesis, followed by hemostasis in the formed sub-pectoral pocket. Silicone endoprosthesis is placed into the pocket. Free edge of DM is fixed in area of submammary fold, then edges of musculus serratus anterior and DM are fixed. Postoperative wound is closed in layers to leave two drainages installed in a bed of the endoprosthesis and in an axillary region – an area of lymphadenectomy.

EFFECT: method enables reducing the risk of postoperative ulcers and extrusion of the silicone implant, reducing traumatism and surgical intervention by eliminating the need to use autologous muscle grafts.
