At present, augmentation rhinoplasty with autogenous costal cartilage is highly praised by many rhinoplastic surgeons, and some doctors even advocate that costal cartilage is suitable for all rhinoplastic patients. Compared with nasal septum cartilage and auricular cartilage, it is not only abundant and easy to carve, but also convenient to obtain materials and relatively easier for doctors to operate.

But there are inevitably some shortcomings: first, abdominal incision will leave scars; Secondly, the deformation rate of costal cartilage after transplantation Autologous costal cartilage leaves the original growth area and is transplanted to the nose, which will have a certain deformation rate. Generally, the longer the graft, the greater the possibility of deformation. This requires attention to the selection of materials, reasonable carving techniques, shortening the relative length as much as possible, reasonable fixation and other operations. Sometimes, even if all the techniques are used reasonably, there will still be a few deformations, and the nasal root will tilt slightly to one side for a long time after operation, most of which are not necessary.
