The external incision is not completely along the alar edge at the junction of nose and face. Some people think that the incision in this position can cover up the scar hyperplasia in the later stage, but this will only lead to the difficulty of suture in the later stage, leaving no extra space, which is not worth the candle. The normal external alar incision is to make an incision on both sides of the alar, along a point above the upper foot edge of the alar, to separate the skin, expose alar cartilage, cut off alar cartilage, cut off a small part of tissue, and then cut off the subcutaneous excess connective tissue and fat, as well as the nasal skin, for suture.
Incision is to make two small incisions under the root of the nose, remove some tissues, and then sew them carefully, retract the alar and raise the nose, so that the nose will become smaller and there will be no scars in the nostrils.
Under normal circumstances, if the nostrils are large, it is more suitable for internal cutting.
If the nostrils are not big, but the alar is thick, this situation is suitable for external incision.
