Rhinoplasty is a nose surgery that changes the form of the nose. It can be performed to improve breathing as well but the main purpose of the surgery is for aesthetic concerns. Septoplasty is a breathing improvement procedure. It straightens the nasal septum, which is a wall inside the nose that divides the nasal airways into right and left sides. When the septum is crooked, it can make breathing through the nose difficult. A septoplasty is frequently performed in conjunction with a rhinoplasty.
