auricular cartilage
Ear cartilage is elastic cartilage with uneven shape and contains a lot of elastic fibers. You can bend at will and twist hard without breaking. The cartilage of the concha cavity behind the auricular fossa is intact, and the knife edge is hidden behind the ear.
Ear cartilage is soft and can't support it. Generally, it is used to lengthen the tip of the nose or columella, and it can also be used to deal with the problem of depression of the nasal floor. ? Using ear cartilage alone for nasal synthesis is limited to the nasal type with good foundation, and it is not necessary to lengthen and raise the tip of the nose. It is simply used to pad the tip of the nose, which plays a role in modifying the tip of the nose and protecting the nasal prosthesis.
Autologous cartilage rhinoplasty
Common surgical schemes for auricular cartilage;
Silicone gel+auricular cartilage pad tip
Bulb+auricular cartilage pad nasal tip
A well-established nose is shaped only by ear cartilage (this is rare)
Nasal septal cartilage
The hyaline cartilage separates the two nasal cavities. In fact, the nasal septum is moderate in hardness and is a very good material for rhinoplasty. Asians, on the other hand, have flat noses, and what they lack is the nasal septum. Therefore, it is difficult to see the surgical scheme of nasal synthesis using nasal septum during the operation. If the measurement is sufficient, it can be used to lengthen the columella and shape the tip of the nose, which is a better autologous material than auricular cartilage.
costal cartilage
Compared with nasal septal cartilage, costal cartilage is harder in texture, more effective in three-dimensional shaping and wider in application. Costal cartilage is generally used, and other cartilage is deliberately not used. Costal cartilage can be used for nose tip shaping, bridge lifting and columella lengthening. But before using costal cartilage, we must do three-dimensional reconstruction CT to check whether costal cartilage is calcified. If calcification occurs, other cartilage must be selected for surgery.
Common surgical schemes:
Enlarged nose bridge+semi-costal cartilage nose synthesis
Total costal cartilaginous nose syndrome
To sum up:
Material hardness: rib >; Nasal septum >: auricular cartilage
Good foundation: auricular cartilage
Poor foundation (pursuing exaggerated effect): semi-costal cartilage/full costal cartilage.
The nasal septum is developed: nasal septum cartilage+ear cartilage.
