Could Ultherapy be performed on a person's neck if that person has some nodules on the thyroid?

Ultherapy is not performed over the thyroid gland.  However, if you are concerned about new nodules on the thyroid, you may wish to prioritize the thyroid first.  Ulthera can provide very positive results on the neck. Raffy Karamanoukian, Los Angeles

Ultherapy is purposely avoided being performed over the thryroid. Although this precaution is observed, it would be prudent for you to have your physician performing your treatment aware of your condition.

The thyroid is not treated with Ultherapy and the energy does not penetrate that deep and therefore there is no concern about damaging the thyroid. Unless you have a goiters thyroid which fills your whole neck, this is never a concern with Ultherapy.
