METHOD OF RHINOPLASTY USING A FLAP OF A CAUDAL PORTION OF A NOSE WING CARTILAGE Russian patent published in 2020 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, specifically to plastic surgery. Subpericartilage layer of the cartilage of the wing of the nose is exposed through its subcartilage incision on the inner side of the nostril by dissecting the skin and the mucosa of the inner cartilage of the wing of the nose along the contour of the caudal edge of the lateral pedicle. Further, marking is made at distance of 2–4 mm from the caudal edge of the lateral peduncle in parallel to the longitudinal axis of the lateral pedicle. Longitudinal line of a lateral pedicle is made along a line of marking without affecting the skin and mucosa of the inner cartilage of the wing of the nose, leaving 2–4 mm of the caudal segment of the nasal cartilage separated from the remaining main segment of the lateral pedicle as a cartilaginous flap. Then, on the inner side of the remaining main segment of the lateral pedicle, a pocket is created by skin detachment and an inner lining of the lower part of the remaining main segment of the lateral pedicle with a width of the separated caudal segment of lateral pedicle 2–4 mm. Further, the cartilaginous flap of the caudal segment of the lateral pedicle is moved under the remaining main segment of the lateral peduncle into the created pocket. Produced "sandwich" structure is fixed with a surgical suture, fixing both segments of the lateral pedicle – the remaining main segment of the lateral pedicle and the displaced separated cartilaginous flap from the caudal segment of the lateral pedicle. Pocket is closed by fixing the skin and the mucosa of the inner cartilage of the wing of the nose of the lateral peduncle with a rapidly resorbable surgical suture.

EFFECT: method enables reinforcing the structure of the lateral pedicle of the nose wing cartilage, enabling visualization of the caudal segment of the lateral pedicle of nose wing cartilage (NWC) with its dissection, which enables to accurately plan the level of dissecting NWC, marking and judging the need to reduce the caudal edge of the lateral pedicle, wherein the given stage of the operation is easily performed, including during the first surgical experience; improved shape and straightening of lateral pedicle, more pronounced decrease of lateral pedicle width in its caudal excess, without risk of nose wing cartilage weakening.
