There are two types of plastic surgery : Reconstructive Surgery & Cosmetic Surgery
reconstructive surgery that restores the form and functions of the nose and seeks to resolve nasal injuries caused by various traumas including blunt, and penetrating trauma and trauma caused by blast injury. Reconstructive surgery also treats birth defects, breathing problems, and failed primary rhinoplasties. Most patients ask to remove a bump, narrow nostril width, change the angle between the nose and the mouth, as well as correct injuries, birth defects, or other problems that affect breathing, such as deviated nasal septum or a sinus condition
cosmetic surgery that improves the appearance of the nose
In plastic surgical praxis, the term primary rhinoplasty denotes an initial (first-time) reconstructive, functional, or aesthetic corrective procedure. The term secondary rhinoplasty denotes the revision of a failed rhinoplasty, an occurrence in 5–20 per cent of rhinoplasty operations, hence a revision rhinoplasty. The corrections usual to secondary rhinoplasty include the cosmetic reshaping of the nose because of a functional breathing deficit from an over aggressive rhinoplasty, asymmetry, deviated or crooked nose, areas of collapses, hanging columella, pinched tip, scooped nose and more. Although most revision rhinoplasty procedures are "open approach", such a correction is more technically complicated, usually because the nasal support structures either were deformed or destroyed in the primary rhinoplasty; thus the surgeon must re-create the nasal support with cartilage grafts harvested either from the ear (auricular cartilage graft) or from the rib cage (costal cartilage graft
