When taking the cartilage of nasal septum, the beauty seeker should lie on his back, put towels on his face and nostrils, and fill his nostrils with gauze to prevent blood from flowing back to his throat. Nasal septal cartilage rhinoplasty usually uses local anesthesia. Through the right nostril, the nasal mucosa was cut from bottom to top at the anterior end of nasal septum 1 ~ 1.5 cm, and separated vertically to the cartilage of nasal septum. Attention should be paid to the integrity of nasal mucosa when cartilage is peeled off. Gently cut the cartilage at the front and upper ends of the nasal septum cartilage above 1cm, reach the opposite side of the cartilage, separate it, and then take out the nasal septum cartilage with the required size. When the septal cartilage is placed between the medial feet of bilateral alar cartilage, it must reach the inferior nasal spine of the columella, and the lobular cartilage is placed in the columella for "shield" transplantation, highlighting the left and right expression points of the nasal tip. Put the remaining cartilage blocks on the support bar to increase the tip of the nose, and you can put 2 ~ 3 pieces. After the appearance is satisfactory, suture the incision intermittently.
