Can Nerve Damage from Ulthera Be Permanent?

Ultherapy treatment is delivery of ultrasonic energy through the skin.  I have personally never seen a motor nerve injury with Ultherapy.  Cutaneous nerves are more likely to be affected with a feeling of "pins and needles" or temporary soreness in the distribution of the nerve. Again, these effects have been temporary. I personally had an Ultherapy treatment at had a slight tingling sensation in one side of my lateral brow area that lasted approximately one week.  I also routinely perform Vaser liposuction which is a higher energy ultrasound treatment delivered below the skin with a probe directly into the tissues followed by liposuction.  In this treatment, any nerve effects have always been temporary, whether they have been motor or sensory.  I believe that the Ultrasound technology is very safe in both of these circumstances.

Ultherapy uses focused beams of Ultrasound to cause microscopic trauma to soft tissue underlying the skin in order to stimulate scarring, otherwise known as collagen formation. As the scar or collagen contracts, the face is lifted and skin is tightened. Any chance of temporary injury to a facial berve is extremely rare, and permenant deficit has never been reported.
