Ultrasonic dissectors (USD) function by using ultrasonic motion to created heat and the resultant coagulation of proteins. USD may be used for cutting and coagulating tissue with decrease in thermal injury to surrounding tissue. Additionally, less manipulation of the thyroid tissue while transecting the vascular pedicles may lead to decreased inflammation. Studies have suggested the use of USD decreases operating time by 10-35%, decreases hospital stay, and decreases intraoperative and postoperative bleeding. [18]
