The types and treatment of scarring are very complex and require scientific diagnosis, a rational approach, and personal operation by a professional doctor. The common types of scarring on the general nasal skin are depressed or hyperplastic, which may cause deformation of the nose. Due to the complex three-dimensional structure of the nose, the treatment of nose scarring requires more consideration for aesthetic repair. Broadly speaking, treatment methods can be divided into two types: surgical and non-surgical treatments. Surgical treatment is suitable for mange scars that cause nose deformation and are large in size. Post-operative treatment also needs to be combined with laser and other comprehensive treatments to achieve a more aesthetic and invisible result. Among the non-surgical treatments, plasma beam therapy or microdermabrasion can be used to treat depressed scarring. Both methods stimulate rapid renewal of collagen and fibrous tissue, removing the aged skin from the scar and regrowing new skin. Plasma beam can even stimulate the regeneration of fibroblasts and elastin and collagen in the deeper layers of the depressed scar, thus restoring flatness to the depressed area. However, the specific treatment method still needs to be personalized according to the individual situation and needs to be treated in a qualified and well-equipped regular hospital, which is something that candidates must keep in mind.
