What are the characteristics of prosthetic rhinoplasty?

There are many ways to perform rhinoplasty. In addition to autologous cartilage rhinoplasty, prosthetic rhinoplasty is a more traditional and popular method. If you choose to have a prosthetic rhinoplasty, there are many things to pay attention to after the operation, such as taking medicine under the guidance of a doctor, avoiding spicy and irritating foods, getting more rest, etc., especially after the operation, you must take measures to prevent infection. The following are some obvious features of prosthetic rhinoplasty.

Features of prosthetic rhinoplasty:

The selection of rhinoplasty materials should be based on the patient's own conditions and economic conditions, combined with the doctor's diagnosis, experience and knowledge.

advantage:

a. Softer than silicone rubber, more natural after surgery.

b. There is no redness of the nose tip after the operation.

c. Tissue can grow into the material, and long-term fixation is better.

d. The nose tip is very soft after surgery. No one can tell that a rhinoplasty was performed unless the patient tells you so.

e. Surgery is also easy to perform on patients with very thin nose skin.

shortcoming:

a. Due to good curing, the material becomes one with the human body and is more difficult to remove than silicone rubber.

Of course, since a one-time surgery can last forever, this problem will only occur when you are not satisfied with the results of the surgery and need another surgery. However, surgeons who have extensive experience with this material generally have mastered special techniques for removal, so there is no need to worry.

b. Higher price than silicone rubber.

c. Sculpture requires rich experience.

d. For adolescents who are in puberty, since all aspects of their body functions are in the development stage, so is the nose. If rhinoplasty is performed at this time, it will easily affect the growth of the nasal bone and nasal cartilage, leading to atrophy of the nose and causing subcutaneous inflammation. You may even have trouble breathing due to swelling in the anus or an upper respiratory infection or allergies.

Advantages of surgery

First of all, the surgical effect of prosthetic rhinoplasty can be predicted, and computer technology can be used to build an accurate and intuitive communication platform between the patients and doctors. Doctors can vividly demonstrate the effects of rhinoplasty to patients in three-dimensional space, and patients can also ask doctors for modification suggestions based on their own aesthetic views, better satisfying patients' desire for "a certain look".

Secondly, prosthetic rhinoplasty requires surgical experts to fit the features of the prosthesis to the features of the patient. Traditional rhinoplasty requires hand-carving of the prosthesis, but the shape of the patient's nasal bones is not understood. Therefore, the prosthesis produced is difficult to fit the nasal bones completely, which can easily lead to sliding, dislocation, prosthesis deviation, and step-like deformity of the root of the nose. Figure 7 shows the situation after rhinoplasty using the traditional method. It can be seen that there is a large gap between the prosthesis and the nasal bone. The patient reported that the prosthesis floated and swayed under the skin, and the nose looked fake after the surgery. The shape of the digital prosthesis comes directly from the computer-reconstructed nasal bone model. At the same time, the thickness of the prosthesis is accurately calculated by analyzing the difference between the simulation effect and the original nose shape, the deformation of the soft tissue in different rhinoplasty areas, and the digital expert experience library. Therefore, the prosthesis is morphologically consistent with the individual characteristics of the patient, fits firmly, and the surgical effect after implantation is exactly the same as the simulation effect.

Finally, biocompatible materials for prosthetic rhinoplasty. Traditional silicone plastic implants are composed of solid silicone rubber material and chemical additives. Although materials containing chemical additives will not cause major safety hazards after being implanted into the human body, they will have a certain impact on the patient's recovery from trauma. Rhinoplasty is filled with expanded polytetrafluoroethylene shear-arti material, which has good biocompatibility, good aging resistance, resistance to high temperature and high pressure steam sterilization, good stability, combination of biological inertness and biological activity, strong and not easy to break, elastic, and can be adjusted soft and hard at will, easy to process, strong plasticity (easy to shape), white, opaque after implantation, and easy to remove. It has been widely used in soft tissue, hard tissue, plastic implants and other fields.
