1. Butterfly incision is used for non-osteotomy. If silicone prosthesis is used for filling, the incision on the upper edge of the nasal vestibule can be used. For mild type I, the method of increasing the height of nasal tip is mainly adopted, and the inflatable reinforcement material is the first choice to make the filling prosthesis. The technical essentials are: firstly, put a ruler on the back of the nose through the root of the nose, and then measure the height, length and shape of the nose tip to be filled from the side.
For mild type ⅱ, the thickness of the central part of the silicone prosthesis or swelling material corresponding to the carina can be reduced and only the two ends of the carina can be filled. For patients with long nose deformity, the same effect as nasal tip filling swelling can be obtained through traditional long nose plastic surgery.
2. The method of bone cutting is mainly to use the incision between alar cartilage and lateral nasal cartilage. Butterfly incision can be used if accompanied by long nose deformity, but the lower end of the incision should extend to the base of nasal columella.
One is to separate from the incision along the cartilage surface and subperiosteal of the nasal bone, up to the nasal root and on both sides of the frontal process of the maxilla. Firstly, the protruding part of the hump on the back of the nose is chiseled, including the nasal bone and septum cartilage, alar cartilage and winglet cartilage. Then lateral oblique osteotomy of nasal bone was performed.
