First, correct the crooked nose at the cartilage cone of the bridge of the nose. After the medial nasal soft and bone scaffold is widely separated from the soft tissue of the nasal dorsum, it can be cut from the northern edge of the nasal septum epiphysis to separate the nasal septum cartilage from the nasal cartilage.

Second, the incision to correct the crooked nose After routine disinfection and anesthesia, pay attention to correcting the incision of the crooked nose. There are two kinds of incisions: one is into the nose and the other is out of the nose. These nose shaping methods have their own advantages. After the incision is completed, subcutaneous tissue, pear-shaped hole and soft tissue inside the nose can be widely separated upward until above the nasal bone.

Third, when correcting the awl of the crooked nose, according to the degree of deviation of the bone vertebra, cut off the frontal process of the maxilla and the nasal bone from the edge of the pear-shaped hole with a bone chisel or a bone saw, and screw off the upper end of the nasal bone with a bone forceps. At this time, the bone cone can be loosened and can be moved with fingers during rhinoplasty.
