METHOD OF OTOPLASTY FOR PROTRUDING EARS Russian patent published in 2024 - IPC A61B17/00 A61F11/20 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to plastic surgery and otorhinolaryngology. When the patient is supine, the boundaries of an S-shaped skin flap are marked on the posterior surface of the auricle in the region of the simulated antihelix. On the skin of the anterior surface of the auricle, four levels of the proposed mattress suture are marked: at the level of the apex of the triangular fossa, the base of the bifurcation of the antihelix, the middle one-third of the antihelix and at the level of the transition to the antitragus. Skin is infiltrated along anterior and posterior surface of auricle with a local anaesthetic solution. Preliminarily made markings on the posterior surface of the auricle are used to make convergent incisions of the skin with excision of a skin strip. Skin is mobilized and the auricular cartilage is dissected along the posterior surface of the auricle. Excess cartilage of the concheal fossa is determined, and 3–4 mm wide crescent-shaped strip of concheal fossa cartilage is excised along the perimeter of the junction with the antihelix. Cartilage edges are sutured together by interrupted sutures using prolene 5-0 suture. Injection needles are carried out through the cartilage through the points marked on the skin of the anterior surface of the auricle for the application of mattress sutures at four levels, namely at the level of the apex of the triangular fossa, bases of the bifurcation of the antihelix, the middle one-third of the antihelix and at the level of transition into the antitragus. Similar points of mattress suturing are marked by injection needles on back surface of cartilage. Cartilage is punctured 2 mm long using the created marking on the anterior surface of the auricle with the use of a scalpel. Plication of antihelix cartilage is performed with formation of its legs. Mattress sutures are applied using prolene 5.0 suture. Entire thickness of the cartilage of the edge of the concheal fossa is pierced and prolene 5.0 suture is passed through the punctures through the preserved subcutaneous fat along the posterior surface of the antihelix at four levels, namely at the level of the apex of the triangular fossa, the base of the bifurcation of the antihelix, the middle one-third of the antihelix and at the level of transition to the antitragus. Haemostasis is performed, the wound is closed by continuous intradermal suture using prolene 5.0 suture.

EFFECT: method of otoplasty in case of protruding ears provides stabilization of cartilage without formation of hypertrophic and keloid cicatrices on skin, allows to form an antihelix without presence of abnormal edges with sharp contours, to provide strong adhesion of cartilages, to improve patient’s quality of life.
