What are the side effects of fat grafting for the cheekbones?

Facial fat grafting to the cheekbones is a cosmetic surgical procedure that enhances the fullness and three-dimensionality of the cheek area by injecting autologous fat or other fillers. Possible side effects include the risk of infection, allergic reactions, fat migration and liquefaction, asymmetry, and nerve damage.

Failure to maintain proper hygiene after surgery may lead to infection at the injection site, causing symptoms such as redness, swelling, and pain. Additionally, injury to small blood vessels during the procedure may result in hematoma formation, which can affect recovery. Although autologous fat theoretically does not cause allergic reactions, medications or materials used during processing and injection may trigger sensitivity reactions. Before the fat has fully stabilized, it may migrate, affecting the filling outcome. If fat particles are too large or clump together, the fat survival rate may decrease, leading to liquefaction. Uneven fat distribution may cause facial asymmetry. Given the dense nerve distribution in the face, improper technique during the procedure could damage nerves, leading to unnatural facial expressions or sensory abnormalities.

To minimize the side effects of facial fat grafting to the cheekbones, patients are advised to choose a reputable hospital and an experienced surgeon before undergoing the procedure, and to fully understand the surgical risks and post-operative care instructions prior to surgery. After surgery, patients should strictly follow medical advice for post-operative care and follow-up visits to ensure both surgical effectiveness and safety.
