Ultherapy or Thermage for neck with an ACDF (titanium screws and plates on cervical spine)?

Ultherapy is safe after ACDF because the depth of penetration of the ultrasound energy is only to the level of the skin and fascia.  There are deep neck muscles which cushion the spine.  Even in a thin neck, the ultrasound energy does not reach the spine and associated hardware.

Ultherapy will not affect your anterior cervical discectomy and fusion. The US energy will not penetrate that deep and in fact, is focused at 4.5 mm only. Read the Ultherapy ebook on the link below.Dr Karamanoukian

Ultherapy is safe with your titanium screws and plates.  One of the biggest advantages of Ulthera is you are able to visualize the treatment area and ensure the depth to which the energy is penetrating.  The deepest Ulthera transducer penetrates to 4.5 mm which would not be deep enough to have any effect on the titanium in your neck.  I would recommend a consultation with an experienced provider who can do a thorough consultation to ensure you are a good candidate and further address your concerns regarding your ACDF procedure.
