Manifestations and causes: Infection. Mainly due to the lack of strict aseptic operation and instrument sterilization, the presence of preoperative foci of infection in the face, or retrograde infection caused by postoperative wound immersion resulting in stitch removal. Skin ulceration. Mostly seen after liquid silicone injection rhinoplasty, which is now very rare due to the disabling of injectable rhinoplasty. Distorted nose. It is caused by the nasal bridge axis is not correct, the nasal septum is distorted, the nasal small column is distorted, the implantation cavity is not correctly separated during the operation, the prosthesis is sculpted asymmetrically, the pressure on both sides of the pressure bandage is not equal, and the postoperative care is not proper. Unattractive nasal shape. The nasal bridge is too high, the nasal bridge is too narrow, the frontal nasal angle lacks curvature, the nasal body curve is stiff, etc., mostly due to inappropriate sculpture of the prosthesis. Prosthesis contour shadow. Due to too shallow implant cavity, poor articulation between the prosthesis and bone surface, too steep dorsal side of the prosthesis, too thick on both sides of the prosthesis, mostly seen after silicone prosthesis rhinoplasty. Rejection reaction. It is manifested as no swelling after surgery, incision not healing and yellow liquid outflow, skin redness, etc., mostly seen in hypersensitive body or poor prosthesis compatibility. How to repair: 1, to solve the skew after rhinoplasty, the lighter one can be reset by manipulation, otherwise, the failed rhinoplasty repair surgery should be done. 2.When the outline of the nasal tip prosthesis shows, the prosthesis should be removed as early as possible, and after six months of observation, decide whether to perform the surgery again according to the specific situation. The second repair can use L-shaped silicone prosthesis rhinoplasty covered with autologous ear cartilage at the tip of the nose to prevent the outline of the prosthesis from showing again. 3.Once the prosthesis is found to float, repair it by implanting the prosthesis under the dorsal fascia of the nose and refrain from sending it into the original tunnel. 4.If the rhinoplasty implant is exposed, the prosthesis should be removed and anti-infection treatment should be strengthened. If the prosthesis is exposed in a small area at the tip of the nose and there is no infection, the double triangular flap method can be used to repair it. 5.If there is any rejection reaction, the prosthesis should also be removed. Three months after the removal of the prosthesis, autologous cartilage or other safe materials can be used for the second surgery. Surgical principles: careful understanding of the damage of the failed rhinoplasty to the candidate before surgery; observation of the nasal shape first to find out the nasal defects caused by surgery; design a reasonable repair plan according to the defects and reasons for surgical failure; sculpting the most suitable nasal prosthesis; ensuring that the prosthesis can be accurately implanted in the nasal cavity during surgery; strict disinfection of the wound after surgery to avoid infection.
