The thicker the prosthesis, the greater the skin tension after implantation, and the more obvious the stimulation to the skin on the back of nose. Especially for beauty seekers with thin skin on the back of the nose, a soft prosthesis should be used for rhinoplasty, and it should not be carved too thick.

In addition, when carving the prosthesis, if the back of the nose is carved too thick, it will cause excessive local pressure, affect the blood circulation of the tissue, and make the rhinoplasty locally red.

2. It is related to the material of the prosthesis.

The material of the prosthesis is hard and may be rejected, which is one of the reasons for the discoloration of the skin on the back of the nose. Domestic silica gel used in the early days is very hard and irritating to tissues because it contains many impurities. Although the high-quality medical silica gel used in recent years is much less irritating to tissues, it can't avoid the shortcomings of rhinoplasty, such as excessive skin tension at the tip of the nose, which will affect local blood circulation and lead to whitening or redness of the skin at the tip of the nose.

Therefore, in the selection of materials, we should first choose artificial materials and autogenous cartilage rhinoplasty which are soft and not prone to rejection, avoid using artificial materials in the nose area, and then eliminate the influence of material defects on the operation.

3. It is related to the void.

Insufficient or shallow peeling of nasal cavity is the cause of nasal skin discoloration. If the stripped cavity is smaller than the space needed for carving the prosthesis, it is easy to make the skin tension after implantation too high, affect blood circulation, and lead to whitening or shining skin. In addition, shallow exfoliation level is easy to cause the implanted prosthesis to stimulate the tissue and change the color of the skin on the back of the nose.
