METHOD OF FORMING PECTORAL FLAP Russian patent published in 2024 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to reconstructive surgery. Skin insula is marked along submammary fold in projection of abdominal portion of greater pectoral muscle so that the central point of the skin island is at the intersection of the submammary and midclavicular lines. Mutually perpendicular lines corresponding to longitudinal and transverse axes of the flap, which are connected to each other in the form of an oval, are laid from this point. Further, the marking lines are continued from the skin island in the projection of the anterior axillary line, skin and subcutaneous fat around a skin island are incised in an oblique direction so that the ratio of the areas of the skin island base and its skin surface corresponds to 2:1. A pectoral fascia is dissected, an anterior surface of the greater pectoral muscle is dissected along its entire length cranially from a skin insula and in an axillary region. Free edge of the greater pectoral muscle is identified and a blunt dissection is performed in the fascial layer separating it from the lesser pectoral muscle. Greater pectoral muscle is detached up to the level of its attachment to the anterior surface of the ribs. Posterior surface of the muscle is separated from the surrounding tissues up to the lower edge of the clavicle. Thoracic-acromial vascular bundle is visualized, greater pectoral muscle is transected along lines parallel to sternum along medial and lateral edges of cut skin insula with preservation of clavicular portion of greater pectoral muscle. Donor chest wound is closed with two rows of sutures, and the wound is drained with a silicone tube.

EFFECT: method enables creating an incision in the axillary region, which in the remote postoperative period solves the problem of aesthetics of the thoracic region and reduces injuries.
