“Closed” Rhinoplasty is performed in such a way as to ensure that all incisions are hidden within the nostril, so there is no external scarring.  The tradeoff here is that there is less the surgeon can do when using this method – fewer tools and procedures are available to the surgeon.  An “Open” Rhinoplasty, on the other hand, leaves a small scar that often times fade after a few months.  The benefits of an “Open” Rhinoplasty is vastly improved functionalities and tools available to the surgeon.  This is especially important if the patient has abnormal or challenging nasal anatomy.
