It's basically not difficult. Rhinoplasty refers to the operation of cushioning the external nose by filling the nose with autologous, foreign tissue or tissue substitutes, thus improving the appearance of the nose. There are two kinds of rhinoplasty incisions: columella incision and intranasal incision, among which the intranasal incision (near columella) is widely used because the incision is hidden and there is no trace on the outside.
