METHOD FOR POSTAURAL FOLD FORMATION WHILE REMOVING TOTAL AURICLE DEFECT Russian patent published in 2017 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: bordering incision is made along the perimeter of the prefabricated auto-rib cartilaginous frame of the auricle. The formed capsule of the auto-rib cartilaginous frame is milled from the underlying soft tissues to the lateral edge of the anti-curvature. A tunnel is formed in the auto-rib cartilaginous frame capsule under the frame itself to the border with the concha fovea. The semilunar graft is modeled from the auto-rib cartilage and placed in the tunnel. At that, three incisions are made in the capsule of the auto-rib cartilaginous frame in the lower pedicle area and in the middle part of the anti-curavture and in the anti-curavture area. Further, three tunnels are formed perpendicular to the course of the anti-curvature to the border with the concha fovea in the auto-rib cartilaginous frame capsule, under the frame itself. Three semilunar grafts with a length of 0.3-0.7 cm, width of 0.2-0.4 cm, height of 0.4-1.0 cm are formed from the auto-rib cartilage. The obtained grafts are placed in the tunnels in the auricle frame capsule parallel to the border of the concha fovea.

EFFECT: method allows to increase the aesthetic result of the operation due to the achievement of the necessary degree of frame retraction along the entire border of the concha fovea for postaural fold formation, to reduce the traumatic nature of the method due to preservation of blood supply to the auto-rib cartilaginous frame capsule of the auricle.
