Hello: I am glad to give you an answer. Nasal vestibular margin incision: it is an arc incision made at the top of a nostril, which is the most commonly used incision in rhinoplasty. The incision at the root of nasal columella has the same characteristics as the incision at the front center of nasal columella. Different incision methods have different effects. I hope my answer is useful to you and I wish you a speedy recovery.
