METHOD OF ELIMINATING DEFECT OF ENTRUM OF NOSE Russian patent published in 2023 - IPC A61B17/24 A61B17/322 

FIELD: medicine; reconstructive surgery and oncology.

SUBSTANCE: preliminary marking is performed taking into account the configuration and size of the defect after removal of the malignant neoplasm. An incision is made from the base of the wing of the nose, along the slope of the nose, to the level of the nasolacrimal groove, as well as from the base of the wing of the nose along the nasolabial fold, according to Fig. 4a. The cut nasolabial fat transposition flap is mobilized and positioned in the area of the nasal vestibule defect. The flap is fixed along the edges of the defect with separate interrupted sutures. The wing of the nose is fixed with interrupted sutures to the displaced flap in accordance with the anatomical position of the symmetrical wing of the nose. After this, the donor wound is sutured layer by layer with an intradermal suture.

EFFECT: method allows for visual control during reconstruction of the nasal vestibule while preserving the natural anatomical contours and achieving aesthetic results without creating additional tension.
