Rhinoplasty: Due to trauma or infection of the nose, the nasal column is partially or completely defective and the nasal wing and tip may be adhered together. Treatment depends on the extent of the defect and whether it is combined with septal lesions to determine the surgical method. The nasal column is too wide and too short: only the excess tissue of the crescent is removed at the inner edge of the anterior nostril. Low nasal column: the commonly used methods are V-Y shaping method and local flap grafting method. Sagging nasal column: The whole septum tissue can be removed in a shuttle shape and the nasal column can be lifted up, or part of the skin and soft tissue can be removed from the edge of the nasal column. Deviation of the nasal column: deviation of the nasal column is often accompanied by deformities of the anterior nostril nasal tip and even the nasal wing, which requires comprehensive treatment. While correcting the nasal column, it is also necessary to correct the position of the nasal tip to make the nostrils symmetrical and the lower part of the nose balanced. Nasal Column Inversion: If the nasal column is invaginated but the tip height is normal, nasal septum cartilage or auricular cavity cartilage graft can be used to fill the invaginated nasal column. If the nasal column is sunken and the nasal tip is low, autologous cartilage or substitutes can be used to shape the nasal column into an L-shape and correct the above two deformities at the same time. In cases of nasal column inversion combined with tight septal tissue, a septal relaxation incision is feasible, with the upper tissue sliding downward and the nasal spine partially chiseled away to relax the lower septal tissue, and the nasal column cartilage is implanted at the same time. It is also feasible to advance a simple rectangular flap of the nasal septum or advance a full-layer V-Y suture of the nasal septum. Nasal Column Defect: Composite transposition method, nasolabial canal method, upper lip flap method, and human middle tipped flap method can be used to repair or shape the nasal column. Rhinoplasty: Oversized nostrils will make people look unrefined and beautiful and affect one’s external beauty, so it is necessary to perform nostril reshaping surgery to narrow the nostrils by making incisions in the nostrils to make the facial features coordinated and more attractive to individuals. Stenosis and atresia of the anterior nostril: nostril stenosis and atresia not only affect breathing, smell and development, but also affect the development of the whole face. In addition to congenital factors, most nostril stenosis and hemispheric atresia are caused by acquired factors such as trauma, burns, scalds or infections. Narrow or atretic anterior nostrils, especially those with scarred narrow or atretic anterior nostrils, require rhinoplasty. Inconsistent nostril size: It may be congenital, such as patients with cleft lip and palate (commonly known as hare lip), often accompanied by inconsistent nostril size. Acquired nostril disparity in size can be caused by disease, trauma, burns, scar contracture, etc. Posterior nostril atresia: Posterior nostril atresia is very rare and can be divided into two categories: congenital and acquired. Nasolabial angle: The standard value of nasolabial angle should be 90°~110°, if it is greater or less than this value, it is theoretically regarded as unattractive. People with saddle nose have larger nasolabial angle and shorter nasal length, forming a skyward nose, which can usually be corrected by saddle nose surgery to lengthen the length of the nose and improve the nasolabial angle. Those with long noses tend to have drooping nasal tips, forming a hawk nose with a small nasolabial angle, which can be corrected by nasolabial angioplasty. The support of silicone prosthesis is used to increase the length of the nose to reduce the nasolabial angle, and local anesthesia is mostly used. Special attention should be paid to the fact that the force of downward support of the tip of the nasal prosthesis should not be large, otherwise it will easily lead to local perforation. Surgical method: 1. Fill the nasolabial angle with cartilage or solid silicone to increase the nasolabial angle. Operation steps: take an incision at the bottom of the nostril, peel off the anterior nasal spine, implant the pre-made rib cartilage or auricular cartilage and solid silicone filling, and suture the incision. 2. Excise part of nasal cartilage and anterior septal cartilage to increase the nasolabial angle. Operation steps: incision and peeling along the nostril margin, or by intranasal incision, excision of excessive anterior septal cartilage and part of the vertical part of the medial foot of the septal cartilage, suture the wound margin. 3. Excise part of the nasal cartilage to elevate the tip of the nose. Operation steps: cut and peel the nasal cartilage at the junction of nasal wing cartilage and lateral nasal cartilage in the nostril, remove part of the cartilage at the junction of nasal wing cartilage and lateral nasal cartilage, then suture the nasal wing cartilage and lateral nasal cartilage, and then close the incision
