Nasal wing plastic surgery mainly includes alar deformity and alar defect. Nasal alar deformity is more common in congenital diseases. Patients with cleft lip are often complicated with alar cartilage dysplasia, alar drooping and alar narrowing, which will obviously affect the overall beauty of the nose. Clinically, there are mainly alar drooping, alar hypertrophy, alar contraction and alar collapse. Compared with alar defect, alar deformity is more common in plastic surgery. If the alar is large and the nostrils are wide, the lower part of the alar base can be carefully removed to narrow the nostrils. If the alar margin is wide, the alar free margin can be partially removed, and the incision can be stitched to the inner surface of the alar after trimming; If the nostril is too big, the alar is too thick or the upper part of alar groove is too full, a skin incision along the anterior edge of the lateral foot of alar cartilage can be made. The alar edge of drooping nose has a harmonious arc, not too high, too low, too straight and asymmetrical. Nasal alar droop can be manifested as anterior, posterior or all alar margin drooping, and the lateral view can cover the columella, forming a false columella invagination deformity. The main treatment methods are as follows: 1. Marginal resection: Dr. Deneckc and Dr. Meyer first proposed to remove the alar margin when treating bilateral cleft lip nose. This method is gradually extended to alar basal resection, which is used for alar drooping plastic surgery and nasal reduction plastic surgery. Check the drooping alar edge and remove it. Extended resection can enlarge the incision to nasolabial groove, but attention should be paid to the smooth and natural edge of reconstructed alar. 2. The method of trimming the alar cartilaginous lateral angle and the subchondral atrium of nasal septum: It was put forward by McKinney and Stalnecker( 1984), that is, the lower edge of alar cartilaginous lateral angle and alar were removed above the nasal cartilage of nasal septum. This method is only suitable for people with thin skin. Chondrotomy of the inferior margin of nasal septum is an effective method to improve the alar and columella. 3. Partial excision of alar lining: A cartilage lining skin on the upper edge of the lateral corner is removed through the incision between the cartilage in the nose, which can also play the role of lifting the alar. However, this method may cause irregular alar edge or abnormal notch, so we should be cautious. Shape your beautiful history and realize your beautiful dreams. As long as you choose a regular large-scale plastic surgery institution, nose wing plastic surgery will open your beautiful life.
