METHOD FOR RECONSTRUCTION OF CICATRICAL-CHANGED DEFECTS OF NOSE TIP Russian patent published in 2024 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: flaps are formed to move to the defect area of the nose tip and to be fixed in the area of the defect. Arched skin incision is made from the upper one-third of the wing of the nose on the right, through the nasal dorsum to the upper one-third of the wing of the nose on the left, at a distance from the existing scar-changed edge of the defect towards the nasal dorsum according to the defect size of 1.5 cm. A full-thickness skin flap of arched shape is cut out and mobilized in the area of nasal dorsum; the base of this flap is a scar-changed edge of the defect. Flap is mobilized and overturned in the area of the existing defect of the nasal tip. Taking into account the defect from the inverted flap in the region of the dorsum, as well as the tip and wings of the nose, a sliding rectangular full-thickness skin flap is formed from the forehead, for this purpose, two vertical incisions are made from an upper one-third of a wing of a nose to the right and to the left, along a nasal bridge, with a transition to a frontal region to its upper one-third. Length of the cuts is equal to three times the vertical size of the defect; cut out full-thickness skin flap is mobilized, haemostasis is carried out and moved to the defect area, fixing with interrupted sutures, while the flap is fixed to the inner surface of the base of the wings of the nose.

EFFECT: method allows performing one-stage surgical treatment, avoiding possible face asymmetry and cosmetic defect of donor area; achieve symmetry of the tip of the nose and a good aesthetic appearance; use adjacent to the defect area tissues having identical characteristics for a better cosmetic result; reduce the period of disability and rehabilitation of the patient.
