Cheek implants have been used since 1956 and have a proven safety record, according to Johns Hopkins Medicine. Though they're typically made out of silicone, they may also be made from Medpor (porous polyethylene), Gortex, or hydroxyapatite (a substance much like tooth enamel and bone), all materials that are all widely used for medical purposes.Â
When placed by an experienced board-certified surgeon, these devices are considered very safe.
That being said, any surgery carries risks, including hematoma, swelling, bruising, numbness from nerve damage, persistent pain, poor healing, and side effects from anesthesia. The incidence of complications with facial implants isn't high, but certain problems may develop which require implant removal.
A study from 2018 reported that the most common complications of facial implant surgery, including cheek implants, were infection, implant migration, swelling, and extrusion.Â
It’s also possible for thick scar tissue to form around the implant (capsular contracture).Â
Implant migration can also be a risk. The scar tissue that forms around the pocket the implants are placed in usually keeps them in position, but while some providers secure the implants to the bone with a tiny screw to ensure they don't migrate, there's no consensus on whether to screw cheek implants to the bone to secure them.Â
Bone resorption (bone loss) has also been reported below solid facial implants, but doctors on RealSelf who have extensive experience with cheek implants don't believe it's a serious—or even valid—concern. "Bone is living tissue, and it remodels. We have been performing cheek implants for over 25 years and have never seen bone resorption be an issue," says Dr. Portuese.Â
Your facial plastic surgeon should explain all of these risks in detail.
