Autologous fat rhinoplasty is a minimally invasive plastic surgery that extracts healthy fat tissues from other parts of the body and injects the fat particles into the dorsal nasal cavity by injection to augment the appearance of the nose after purification, cleaning and other treatments. The risks of the surgery are as follows: 1. Post-operative infection: If the operation is not strict or the post-operative care is not proper, it will lead to swelling, redness and other infections in the nose; 2. Localized skin necrosis: The main reason is that the fat particles mistakenly enter into the blood vessels during the injection, which will easily lead to localized necrosis of the skin, and in serious cases, it will lead to vascular embolism. If the fat particles are inadvertently injected into the blood vessels in the nose, it may lead to blindness; 3, poor nasal shape: if it leads to widening of the nose or the height of the bridge of the nose is insufficient in the long run, and the fat can be partially absorbed, the candidate may need to take several supplemental injections. Therefore, when choosing autologous fat rhinoplasty, candidates need to choose professional and experienced doctors, after an interview candidates need to combine the specific conditions of the individual, to choose the most appropriate surgical program, not only to protect the safety of the operation, but also to obtain good surgical results.
