Whether it is necessary to reduce the alar of the nose must be evaluated and judged after the nose tip surgery. When the alar is wide, it is mostly because the alar skin is redundant. We need to cut off the skin under the alar and sew up the incision to narrow the alar, which will make the nostrils look very long. The incision is left at the junction of nose and cheek, and the scar is not obvious. There are three cases of alar reduction surgery: 1. If the alar is wide and the nostril is wide, partial resection of alar base and nostril reduction can be performed cautiously. The incision is located at the base of alar and the lower part of alar sulcus. Under local anesthesia, part of the full-thickness tissue of the alar base was properly removed, and then the nostril was rotated inward to narrow and sutured intermittently in layers. The length of scar visible after operation is generally less than 1CM. 2. 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. 3. If the nostril is not big, the alar is too thick or the upper part of alar groove is too plump, you can make a skin incision along the front edge of the lateral foot of alar cartilage, secretly peel off the lower skin and alar cartilage, cut off the swollen soft tissue on the cartilage surface, and then appropriately remove the upper and lateral parts of alar cartilage; Then cut off a diamond-shaped vestibular skin and nasal mucosa in the nostril, and cut off excess adipose tissue. Finally, the incision on the edge of the nostril is stitched with the incision on the inner side of the base of the alar. The length of scar visible after operation is generally less than 1CM. In general, the outermost nostril does not exceed the vertical line of the inner canthus, otherwise the alar will be enlarged. When the alar is wide, the nostrils will appear very large. If the nose is wide, even if the nose is not low, it will appear very low. When the nose is lower and the alar is slightly wider, only rhinoplasty can achieve the natural effect of narrowing the alar.

Edit the preoperative precautions for reducing the alar in this paragraph.

First of all, [1] before the operation, female friends must not wear makeup to avoid menstrual period; For male friends, quit smoking one week in advance; And do not take drugs containing aspirin within two weeks before operation, because aspirin will reduce the coagulation function of platelets; Do a professional preoperative examination. If there are patients with hypertension and diabetes, they should inform the doctor of their condition at the time of initial diagnosis, so that the doctor can confirm the nasal alar plastic surgery plan. There is also to make sure that you are healthy before surgery, and there is no infectious disease or other body inflammation. It should be said that as long as we can attach great importance to the above contents, and then go to a regular hospital for professional nose-nose-alar reduction surgery, we can get satisfactory nasal plastic surgery results.

Edit the nursing precautions after nasal alar reduction in this paragraph.

1. Within a few weeks after alar reduction, wearing glasses outside can effectively cover up the surgical traces. Put some foam material or band-aid under the glasses frame to avoid the discomfort caused by long-term pressure on the glasses. 2. The makeup method to cover up the swelling and hypertrophy of the nose is: use a light or white makeup cream at the tip of the nose and a slightly darker makeup cream at the side of the nose, which can make the nose three-dimensional and appear taller. In this way, people's attention to your nose width can be reduced. 3. Removal of nasal scab after alar reduction: First, gently put a cotton swab into the nostril with water or vaseline to make the cotton swab cling to the scab skin, so that the dry scab can absorb water and soften, and the softened nasal scab can be gently dipped out with a cotton swab. In order to prevent dry scab, wipe it with a wet cotton swab several times a day for several days or weeks. 4. Bleeding after alar reduction; Bleeding mostly occurred 5 days after operation, and the bleeding site was mostly under nasal cavity 1/3. Holding the lower 1/3 of nasal cavity and nostril by hand can effectively stop bleeding. When nosebleeds, you should sit forward to avoid supine position, so as to avoid vomiting caused by blood flowing into the pharynx. Spit out the blood in your mouth, not swallow it. 5. Wound bruise: After the alar reduction operation, cold compress of eye ice pack can reduce the swelling of nose and eyes. Eye swelling causes an increase in eye secretions, which can be wiped clean with cotton swabs dipped in water and normal saline. 6. Within a few weeks after alar reduction, the sense of nose is reduced, and there may be an embarrassing situation of unconscious runny nose. Patients should bring some toilet paper in case of emergency. In addition, the nasal sensation decreases, and the protective response to injury is slow, so attention should be paid to protection. To avoid frostbite, burns and other injuries. 7. After removing the bandage, the patient can clean his face and head. Before this, the patient can gently wipe the exposed part of the face with a wet soft towel. For the next 6 weeks, patients should be careful and gentle when washing their faces, and avoid violent rubbing. When washing your hair, you should have the help of others, take your head back and avoid bowing your head.
