Can You Get Ultratherapy with a Titanium Piece in Your Cheekbone?

While Ultherapy should not be performed directly over metal or other types of implants, the ultrasound technology is such that the doctor can visualize the exact location treatment is reaching, so the implant can be avoided. I recommend visiting a board-certified dermatologist with extensive experience using Ulthera.

Ultherapy uses microfocused ultrasound and does not work well over a highly dense metal. The procedure can still be performed, but care must be taken to avoid the area of concern. Our office regularly performs customized Ultherapy treatments in Los Angeles. 

Your physician has a monitor that allows him or her to visualize the plane of penetration of  Ultherapy. If the monitor shows the implant and the energy won't be delivered that deeply, then it probably is safe. Certainly, the doctor can use Ultherapy and treat around the implant.
