Internal alar surgery is a common plastic surgery method to improve the appearance of nose. By cutting a wedge-shaped full-thickness tissue at the base of the alar, the nostrils can be adducted and the vault raised, thus raising the tip of the nose. This is because alar tissue has an important influence on the shape of nasal tip. Through the operation of cutting the alar, both sides of the alar will also be tightened inward, so that the alar is not so wide visually. The effect of internal alar surgery varies from person to person. The specific results of the operation are influenced by many factors, including the anatomical structure of the nose and the shape of the nose before the operation. When considering the operation of internal alar, it is suggested to consult a professional plastic surgeon for detailed evaluation and discussion, so as to understand the expected effect of nasal tip elevation operation and fully understand the risks and complications of the operation.
