METHOD OF SURGICAL REMOVAL OF CLOSED EAR DEFORMATION Russian patent published in 2024 - IPC A61B17/00 A61F11/20 

FIELD: medicine; maxillofacial surgery.

SUBSTANCE: method consists of two surgical stages. At the first stage, plastic surgery of local tissues is carried out, preserving the resulting excess skin and using it in the second stage. During the first stage, a fragment of costal cartilage is implanted, covered with a rotated sheet of superficial temporal fascia and moved into the previously left skin pocket. An incision is made in the skin and cartilage from the dorsal surface of the auricle parallel to the course of the intended antihelix along the entire length of the cartilaginous part of the auricle without damaging the integrity of the perichondrium from the anterior surface. Then the incisions are made parallel to the previous incision, retreating 1.5–2 mm from each other. Further, these incisions continue towards the upper cartilaginous edge in the form of diverging rays. The formed cartilaginous strips, gradually expanding from the base to the edge, are mobilized. The anterior edge of the auricle is cut off from the temporal region. The shape of the auricle is compared in the new position, the cartilaginous strips are fixed in the new position to each other with long-absorbable monofilament. The skin flaps along the edges of the wound are placed back on top of the formed auricle, preserving the resulting excess skin. Next, forming rollers soaked in Levomekol, Heparin and Vasilin ointments are placed above and below the antihelix. They are fixed with U-shaped sutures. The second stage is carried out after 1 year. A skin incision is made in the temporal region, 1 cm away from the edge of the auricle. The skin flap is mobilized and the cartilaginous part of the helix is exposed. A fragment of a costal cartilaginous autograft is implanted, restoring the relief and size of the opposite relatively healthy ear. It is fixed to the cartilaginous rudiment. The parietal branch of the superficial temporal artery is ligated below the site of the intended incision. A fascial flap is cut out and mobilized on the feeding pedicle with the base facing the auricle. Next, the fascial flap is tilted along with the feeding vessel by 180°, covering the cartilage autograft and a part of the auricle's own cartilage. Vacuum aspiration is created by introducing active drainage under the fascia. Skin flaps are placed over the auricle. The wound is sutured. The forming rollers soaked in Levomekol, Heparin and Vasilin ointments are fixed with U-shaped sutures above and below the antihelix. The drainage is removed.

EFFECT: method makes it possible to increase the efficiency of eliminating deformation of the folded auricle due to a deficiency of cartilage tissue, reduce the trauma of surgical treatment, preserve local tissue, reduce the number of cicatricial deformities, and reduce the risk of postoperative complications.
