1. Operation lengthening method: By making incisions on the nasal columella and the lower edge of both nostrils, the muscle direction is reconstructed and the longitudinal direction is prolonged, which can prevent people from shortening and leaning back. There will be 2-3 mm incision marks under the columella after operation, which are not obvious after fading.
2. Injection method: Botulinum toxin injected into both nasal alars can prolong the human body and prevent shortening and falling back, but Botulinum toxin can be metabolized by the human body and needs to be injected once a year.
