⑴ Prolonging the length of nasal skin: Make butterfly-shaped incision at the tip of nose and the edge of alar, and peel it up and down. The depth of peeling is the surface of nasal bone and nasal perichondrium, and the peeling range is from the top to the eyebrow, the bottom to the upper lip, and the left and right to the zygomatic arch, so that the skin between the eyebrow and the maxilla is pushed to the nose, which can generally increase the length of the skin on the back of the nose by about 65438±0.5cm.
⑵ Nasal lining: The nasal bone and cartilage were fully exposed, and the periosteum was arcuately cut at the upper edge of the pear-shaped hole of about 1.5cm, and the periosteum was lifted and shifted downwards to form a nasal bone periosteum flap pedicled below. The nasal periosteum was separated from the nasal septum mucosa, and the nasal septum mucosa was cut horizontally. At this time, the pear-shaped square runs through the nasal cavity and peels off along both sides of the pear-shaped hole, so that the lower part of the nose (including cartilage) moves down, and the periosteal flap is sutured with the upper edge of the pear-shaped hole to cover the perforation defect.
⑶ Nasal bracket: Autologous iliac bone and autogenous costal cartilage are commonly used at present. Medical silicone rubber is rarely used because it is insoluble and will cause skin necrosis when exposed to tension. Carve cartilage or bone into an "L" shape and implant it under the fascia of the back of the nose. The nasal columella bracket should be close to the nasal spine and fixed with wire or steel wire.
⑷ Bone grafting of superior alveolar bone: For severe saddle nose deformity, bone grafting should also be carried out on both sides of pear-shaped hole to raise the root of nose and correct the concave deformity of face 1/3. Incision was made at the sulcus of the upper teeth in the oral cavity, and subperiosteal dissection was done along both sides of the piriform hole to form the subperiosteal cavity. Carve cartilage or bone into the same shape as pear-shaped hole, implant it into pear-shaped hole and upper tooth groove, and fix it with steel wire.
In order to ensure good postoperative results, saddle nose must go to regular plastic surgery hospitals, Xiamen, Xiamen and Meilai for surgical treatment.
