METHOD OF REPLACEMENT OF SUBTOTAL SKIN-MUCOUS-CARTILAGINOUS DEFECT OF END PART OF NOSE AND UPPER LIP SKIN IN CASE OF PARTIALLY PRESERVED WINGS OF NOSE Russian patent published in 2012 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely to reconstructive regenerative surgery and can be applied in treatment of vast defects of nose and upper lip skin with partially preserved wings of nose. Essence of method lies in cutting out skin-fatty flaps in cheek area on edges of nose defect and closing wound surface if end part of nose with skin flap. First skin-mucous-cartilaginous defect of end part of nose and upper lip skin is formed. After that skin-fatty nasolabial flaps are cut out on both sides of defect 5-7 mm below nose cavity bottom. With base facing upper lip, and top, facing internal angle of eye, leaving 5 mm to the edge of lower eye-lid. After that, in area of nose wings near medial side of each skin-fatty nasolabial flap from their base to partially preserved nose wings made is a cut at angle 45-50°. Triangular flaps with bases, facing nose wings are formed. After that mobilisation of skin-fatty nasolabial flaps and triangular flaps is performed undercutting partially preserved nose wings. Bottom of nose cavity is formed by bringing each skin-fatty nasolabial flap under undercut partially preserved nose wings and their laying on wound surface of nose cavity. Medial sides of each nasolabial flap are fixed to remaining skin of upper lip. Lateral side of flap is fixed with sutures to mucous membrane in lower parts of remaining bone part of nasal septum. Nasolabial flaps are bent is projection of medium line upwards and sewn to each other. After that internal lining of nose arch and nose tip are formed, bending end parts of nasolabial flaps towards nose wings and fixing to them by means of sutures. After that, bridge flap is formed on dorsum of nose with U-shaped cut on glabella. After mobilisation it is displaced to newly created nose tip and sewn with medial edges of skin-fatty nasolabial flaps. Edges of donor wounds of skin-fatty nasolabial flaps are mobilised and sutured. Triangular flaps are sewn into lower parts of donor wounds. Donor wounds are sutured.

EFFECT: application of claimed invention makes it possible to simultaneously form and replace subtotal skin-mucous-cartilaginous end defect of part of nose and upper lip skin in case of partially preserved nose wings, restore bottom of nasal cavity and upper lip skin, eliminate necessity of creating additional donor wound, provide full feeding of nasolabial flaps.
