Fat filler temple is the safest and ideal filling method at present, using negative pressure to extract excess fat from fat-rich parts of the body, and after special treatment such as filtration and purification, it is injected into the temple in a fixed, quantitative and hierarchical manner to fill the sunken temples with fullness and roundness. Because autologous fat belongs to its own tissue, there will be no rejection after injection, but if you choose an irregular, unqualified institution to operate, it can lead to the following hazards: 1, vascular embolism: whether with autologous fat, or other filler materials, in the process of filling the temples, it is possible to inject the filler into the blood vessels, and once this happens, the consequences are often more serious. If the filler blocks the small blood vessels, the local skin of the blood supply will be blackened, ischemic and necrotic, and the candidate will feel pain, and the degree will gradually increase. If the filler blocks a large or important blood vessel, such as the ophthalmic artery, it can lead to blindness. In more serious cases, the filler will reach the lungs with blood circulation, leading to pulmonary embolism and even death; 2. Hematoma and infection: Although autologous fat filler temples belong to microplasty, they also belong to the scope of surgery, and hematoma or infection may occur after surgery, which can be accompanied by local symptoms such as redness, swelling, heat and pain; 3. Aesthetic problems: If the amount of filler is too large at one time, it will affect the facial contour; the amount of bilateral filler cannot be completely consistent, which may lead to poor symmetry of the temples and affect the aesthetics.
