Under normal circumstances, the outermost nostril does not exceed the vertical line of the inner corner of the eye, otherwise the alar will increase. When the alar is wide, the nostrils will appear very large, so even if the nose is not low, it will appear very low and a little dull. Nasal alar reduction surgery is to choose different methods according to personal circumstances to make the nose more exquisite and perfect. 1, Simple rhinoplasty When the nose is low and the alar is slightly wide, only rhinoplasty can achieve the natural effect of narrowing the alar. You can also insert an auxiliary column into the nasal columella and transplant cartilage at the tip of the nose, so that the tip of the nose will stand up and the alar will shrink without other operations. 2. Nose wing adduction: Nose wing thickness, width and flatness are common in China. It can be narrowed by cutting off the lower part of the alar, or it can be pulled closer to the middle by cutting off the base of the thick nostril, which will have a good effect of alar plastic surgery. 3, nasal alar skin resection: when the nasal base is too wide or the nostrils are too large, it means that the nasal alar skin is redundant, and it is necessary to make an incision at the junction of the nasal alar and the cheek, and remove the nasal alar skin by 5-8mm, which can narrow the nasal alar and make the nostrils from flat to long. The tip of the nose can also be raised. 4, alar thinning surgery: remove part of the fat and connective tissue above the alar cartilage, if necessary, remove part of the cartilage, which can make the nose look thin, small and exquisite. Whether the alar reduction operation will leave scars depends mainly on the doctor's level. Experienced doctors will put the incision in the most hidden place, and reduce the tension of suture as much as possible, and cooperate with the anti-scar treatment after operation, so that the final scar will be extremely inconspicuous.
