The methods of alar reduction surgery include excision and injection of botulinum toxin. Nasal alar reduction surgery is to achieve the reduction effect by removing excess cartilage or tissue from the alar. However, the excision operation is aimed at the redundant cartilage in the alar part, and the injection of botulinum toxin is aimed at the muscular situation in the alar part. Botulinum toxin can effectively make muscles contract temporarily, so as to achieve the effect of narrowing the alar. The specific method should be determined according to the specific situation of each person's alar. It is recommended to choose a professional regular hospital.
