METHOD FOR ELIMINATION OF EXTERNAL NOSE DEFECT BY IMMERSED PARAMEDIAL FLAP FROM FOREHEAD Russian patent published in 2025 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to maxillofacial, reconstructive, plastic surgery, otorhinolaryngology, oncology. Surgical field is marked, soft tissues are hydroprepared. Inner lining of the nasal cavity is formed by performing skin incisions around the edge of the defect, mobilizing and rotating the obtained flaps. Then, an individual template is modeled along the contours of the formed defect. Paramedial forehead flap is marked. Then, after hydropreparation of soft tissues, the skin is incised along the marked marking with an electrocoagulator in cutting mode. Adipocutaneous flap is mobilized together with the fibers of the frontal abdomen of the frontal-occipital muscle to the projection of the origin of the supra-block artery and vein. Further, the flap is mobilized subperiosteally with preservation of the vascular bundle. Tunnel is formed in subcutaneous fat layer in area of external nose and bridge to edge of wound defect. Thereafter, the outer surface of the flap is de-epidermised with a scalpel. Flap is rotated by 180 degrees medially, delivered in the tunnel towards the nasal defect. Flap edges are distributed along the wound perimeter and fixed. Skin defect in the donor area is closed and a pressure bandage is applied. Drainage with active aspiration is brought into the wound.

EFFECT: method enables complete elimination of the defect of external nose and nasal cavity, higher aesthetic and functional result due to one-stage reconstruction, reduced risk of perioperative complications.
