Histological Characterization After Treatment With the Ulthera® System

Up to 6 subjects will be enrolled. Subjects who have already chosen to have a surgical facelift procedure will be enrolled. Subjects will receive selective Ulthera® ultrasound exposures in the pre-auricular regions. Subject will return for a follow-up visit up to 48 hours post-treatment, on the day of their rhytidecomy. Study images will be obtained pre-treatment, immediately post-treatment, and at the follow-up visit.

This study is a prospective, single-center clinical trial. Subjects will be enrolled at the investigator's discretion if they meet inclusion/ exclusion criteria and provide written informed consent. Enrolled subjects will be treated with an assigned transducer based on their order of enrollment. At the study follow-up visit, subjects will undergo resection of the treated tissue for histological analysis prior to their planned rhytidectomy procedure.

• Active Comparator: Subject 1
  Ulthera treatment will be administered to both pre-auricular regions using a 4 MHz, 4.5mm depth transducer at 1.2 Joules and 30 Watts on the Left side versus 0.9 Joules and 30 Watts on the Right side.
  Intervention: Device: Ulthera Treatment
• Active Comparator: Subject 2
  Ulthera treatment will be administered to both pre-auricular regions using a 7 MHz, 3.0mm depth transducer at 1.05 Joules and 25 Watts on the Left side versus 0.75 Joules and 25 Watts on the Right side.
  Intervention: Device: Ulthera Treatment
• Active Comparator: Subject 3
  Ulthera treatment will be administered to both pre-auricular regions using a 7 MHz, 3.0mm depth transducer at 0.45 Joules and 15 Watts on the Left side versus 0.35 Joules and 14 Watts on the Right side.
  Intervention: Device: Ulthera Treatment
• Active Comparator: Subject 4
  Ulthera treatment will be administered to both pre-auricular regions using a 10 MHz, 1.5mm depth transducer at 0.25 Joules and 5 Watts on the Left side versus 0.18 Joules and 5 Watts on the Right side.
  Intervention: Device: Ulthera Treatment
• Active Comparator: Subject 5
  Ulthera treatment will be administered to both pre-auricular regions using a 4 MHz, 4.5mm depth transducer at 0.9 Joules and 30 Watts on the Left side versus 7 MHz, 4.5mm 0.9 Joules and 25 Watts on the Right side.
  Intervention: Device: Ulthera Treatment
• Active Comparator: Subject 6
  Ulthera treatment will be administered to both pre-auricular regions using a 7 MHz, 3.0mm transducer at 0.35 and 14 Watts, and a 4 MHz, 4.5mm depth transducer at 0.9 Joules and 30 Watts on the Left side versus a 7 MHz, 3.0mm depth and 4.5mm depth transducer at 2.0 Joules and 40 Watts on the Right side.
  Intervention: Device: Ulthera Treatment
