According to experts, under normal circumstances, the nose is red after rhinoplasty, and under abnormal circumstances, the nose is red after rhinoplasty. Under normal circumstances, the nose is red after rhinoplasty, and it is normal for the nose to be red and swollen within one week after rhinoplasty. Experienced rhinoplasty doctors have little trauma during the operation, and the redness disappears after 1-3 days, but this is also related to personal physique, but most people can dilute the redness and reduce the swelling in one week. But if this phenomenon does not disappear after a week, we will go to the hospital for treatment. Causes of nose redness after rhinoplasty: 1. The redness of nose after rhinoplasty is related to the material of 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 disadvantage that once the tip of the nose is excessively raised, the skin tension of the tip of the nose will easily affect the local blood circulation, resulting in whitening or redness of the skin of the tip of the nose. 2. Nose redness after rhinoplasty is related to the stripped cavity. Insufficient or shallow cavity peeling 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.
