METHOD OF FORMING MEMBRANOUS PART OF NASAL SEPTUM Russian patent published in 2024 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to maxillofacial and plastic surgery. Arc-like incisions are made on both sides in the area of the wings of the nose in the direction to the nasal septum with distance of 4–5 mm. Then incisions are made along rims of wings of nose to places of transition of wing of nose into membranous part of nasal septum. Triangular skin flaps are formed with bases at the skin part of the nasal septum and rounded apices. Length of the base of the triangular skin flaps is the length of the filtrum of the upper lip minus the length of the existing membranous portion of the nasal septum. Cut out triangular skin flaps are mobilized. In the membranous portion of the nasal septum, the mucosa is incised in the direction of the nasal cavity with transection of alar cartilages over a length equal to the length of the base of the cut triangular skin flaps. Thereafter, the mobilized mucous-cartilaginous fragments of the nasal tip are displaced upwards and anteriorly, and the edges of the wounds in the area of the wings of the nose are sutured together by combining points "a" and "b" according to Fig. 1–2. Formed wedge-shaped defects of the membranous part of the nasal septum are filled with cut and rotated triangular skin flaps.

EFFECT: method enables forming the membranous portion of the nasal septum in the correct ratio to the size of the filtrum of the upper lip, as well as the physiologically correct longitudinal-oval configuration of the nostrils while eliminating the deformation of the nasal tip.
