At present, most rhinoplasty operations form an incision with a length of about 1 cm on the inner side of the nostril edge at the junction of the nasal columella and the alar, and a spacious cavity is separated under the fascia of the nasal dorsum or/and the periosteum of the nasal bone through this incision, and then the prosthesis is carved according to the requirements of patients and the skills of doctors, or the already carved prosthesis is directly implanted. Some complicated operations often need to make an incision on the columella, and an inconspicuous scar will be left on the columella after operation.
