Common autologous cartilage is divided into costal cartilage, ear cartilage and septal cartilage, and the materials selected for different nose foundations are also different.
Auricular cartilage is elastic cartilage, easy to carve, and the wound is hidden, so it will have no impact on the appearance of the ear after healing. Seven characteristics of ear cartilage rhinoplasty; 01 good tissue compatibility and stability; 02 relatively simple operation; 03 easy to carve and shape; 04 real touch; 05 hidden scars; 06 the cutting amount basically meets the needs; 07 small complications and damage. Costal cartilage removal may be complicated by significant pain and occasionally pneumothorax; while ear cartilage removal has fewer complications.
Septal cartilage rhinoplasty refers to a surgery that uses autologous nasal septal cartilage transplantation as rhinoplasty material; it can be used to raise and extend the nasal tip and columella to solve the problem of low and flat nose tips and upturned noses. , short columella and low nasolabial angle. It is a better way to sculpt the nose shape, but it is not suitable for those with insufficient cartilage development. It is part of autologous tissue transplantation, which avoids the rejection of allogeneic tissue and is highly safe; the nasal septum cartilage removal surgery and the nasal columella lengthening surgery are performed in the same surgical incision, without the need for a second surgical area in other parts of the body, and the total wound area is decrease.
Autologous costal cartilage: Costal cartilage combines the advantages of the first two types and improves the shortcomings. Autologous costal cartilage has a large supply, is easy to obtain, has strong plasticity, is easy to carve, has moderate texture, and is supportive enough to lift and extend the tip of the nose without causing perforation. However, there will be pain at the place where the ribs are removed after surgery, and there is a possibility that the costal cartilage will be absorbed.
In summary, ear cartilage is suitable for shaping the nose wing and protecting the tip of the nose, but is not suitable for lifting and extending the tip of the nose. Nasal septal cartilage can support the nasal dorsum, columella, and nasal tip, but it is not suitable for short noses and short noses. Costal cartilage is suitable for raising and lengthening the tip of the nose, but there is a possibility of absorption.
The silicone used in silicone rhinoplasty is medical silicone rubber. It has good elasticity, soft feel, easy to shape, good chemical properties, non-toxic, non-carcinogenic, non-teratogenic, and has good tissue compatibility. good. ?After the prosthesis is implanted into the body through rhinoplasty surgery, there may be a mild one-time inflammatory reaction locally, and later a thin layer of fibrous capsule will be formed around it. Therefore, safe and qualified silicone rhinoplasty materials can be carried for life if nothing happens.
