Anesthesia and choice of incision: The surgery can be performed under local or general anesthesia. If a rhinoplasty or rhinoplasty is required along with the correction of a wide nasal deformity, we usually choose an open rhinoplasty incision across the nasal columella to the nasal flank margin on both sides, combined with an incision in the lateral wall crease of the nasal vestibule. In case of simple correction of wide nasal deformity, instead of nasal column incision, the nasal wing cartilage and lateral nasal cartilage incision combined with lateral nasal vestibule wall crease incision is chosen. The bottom edge of the wedge is located at the caudal edge of the nasal bone and the tip ends at the nasal frontal suture, close to the midline. The osteotomy is usually done with a 2 mm wide precision bone gouge. The first osteotomy line follows the bony septum from the caudal end of the nasal bone upward parallel to the midline and ends at the nasal frontal suture; the second osteotomy line starts lateral to the start of the first osteotomy line and cuts diagonally upward to meet the first osteotomy line at the nasal frontal suture. The width of the wedge-shaped bone block is determined according to the actual need, generally 2~3mm. Lateral osteotomy method: A skin incision of about 10mm in length is made through the lateral wall crease of the nasal vestibule, and the periosteal stripper is used to peel off the bone in the direction of the osteotomy line immediately above the superficial layer of the periosteum to the level of the lower edge of the nasal prominence of the frontal bone, which is the end of the lateral osteotomy line. When stripping the tunnel, the periosteum should be kept intact, and the tunnel should not be too wide, 3~5mm is sufficient. Take a single wing fine bone chisel to cut the bone plate from the lower edge of the maxillary nasal eminence along the osteotomy line inward and upward. The osteotomy line should be advanced along the basal line of the maxillary frontal eminence. Near the medial canthus, the line is turned to the medial midline. The osteotomy can usually be stopped when the medial bone mass is felt to be significantly loose. After completing the bilateral osteotomy, the dorsal nasal bone plate medial to the osteotomy line is squeezed with the thumb, and the bone plate is felt to have moved inward significantly and a bony depression appears, which indicates that the osteotomy is adequate. Moderate squeezing will narrow the nasal dorsal base to a satisfactory degree, and the bone block will recover without rebound after releasing, which means the deformity correction is in place. Postoperative treatment: The nasal dorsum was fixed and shaped with plaster for 3~4 weeks after surgery, and the plaster was replaced once a week as the soft tissue swelling of the nasal dorsum subsided. The sutures will be removed one week after surgery.
