There are various factors that cause a round nose, including subcutaneous tissue, skin and cartilage. The skin tissue of the tip of the nose is different from that of the back of the nose. The skin tissue of the tip of the nose is thick and rich in sweat and sebaceous glands, while the skin of the back of the nose is more relaxed and thin. The cartilage of the nasal tip is mainly supported by the nasal wing cartilage and the nasal septum cartilage, of which the hypertrophy of the fornix of the middle foot is one of the important factors leading to the rounding of the facial nasal tip. The shape of the lateral foot of the nose also has a decisive mechanism of action for the shape of the nose as well as the nasal tip. Round nasal tip can be corrected surgically, and the surgical procedure broadly includes both suture method and implantation method. The suture method is a direct vision suture treatment of the cartilage at the tip of the nose to achieve the purpose of rhinoplasty. The specific methods can be subdivided into strut sutures, nasal apex generation sutures, nasal apex balance sutures, septal sutures in the nasal columella and lateral foot closure sutures. The implantation method means that autologous cartilage or prosthesis is used to fill the tip of the nose for the purpose of improving the round nose. Candidates should go to a regular hospital and choose a suitable procedure for themselves under the advice of a physician.
