METHOD OF REMOVING THE DEFECT AND DEFORMATION OF OUSTEOHONDROUS ZONE OF THE NOSE Russian patent published in 2018 - IPC A61B17/00 A61B17/24 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely, maxillofacial and anaplastic surgery, and can be used to eliminate functional defect of nose formation. Hydropreparation of the skin in the tip of the nose and lateral nasal wall is conducted. Inverted V-shaped incision of the skin in zone of columella is performed. It continues with two marginal intranasal incisions on atrium of the nasal passages. Adipo-dermallayer sheet and perichondrium are mobilized, exposing the upper and lower lateral cartilages. Osteotomy of nose’s ossas and exsection of chondral structures are carried out. Autograft is positioned in zone of defect and deformation of osteohondrous part of the nose. Floating palatal connective-tissue autograft is used as the autograft. Autograft is taken in the bony palate zone by aquadissection of mucous coat of bony palate, conducting two parallel incisions of the mucous coat from the canine to the second cheektooth of maxillary bone, receding from the gum margin 3–5 mm, spaced 5–15 mm apart each other. Free palatal connective-tissue autograft is 5–25 mm in length, 5–15 mm in width is taken.

EFFECT: method allows to eliminate defect and deformation of the osteohondrous part of the nose with high functional and aesthetic results, minimize injuries to the donor’s zone by using the floating palatine subepithelial connective tissue autograft used as a soft-tissue autogenic interseptum between osteohondrous structures and skin integuments, choosing safer and less prone to the complication of the donor’s zone and simplification of the method of taking floating palatal connective tissue graft.
