Endonasal rhinoplasty which goes by its other name of closed rhinoplasty allows surgeons to reshape the nose by making all surgical cuts inside the nostrils. Open rhinoplasty differs from closed rhinoplasty because it uses external incisions across the columella but closed rhinoplasty conducts all surgical incisions inside the nostrils while removing any chance of scarring. https://www.scarlessnose.com/blog/what-is-closed-rhinoplasty/
