The patients were weighed before starting the treatment and at every follow-up and were compared.Ī–C, Markings for areas treated by Ulthera, in all patients. During their treatment procedure, patients assessed their levels of perception of pain and improvement on a 10-point scale (0 = no pain 1–4 = mild pain 5–8 = moderate pain 9–10 = severe pain). Similarly, patients used the Subjective Assessment Scale to assess their results at the 6-month evaluation period. If the correct image was identified as posttreatment image, then only the assessment was considered as an improvement. If a change was observed, the reviewer was asked to identify the posttreatment image. The investigators were given pretreatment and posttreatment photographs of the patients in a paired manner to determine if discernable clinical improvement was noted. Efficacy from baseline to 6 months was rated quantitatively (objectively) by 2 independent investigators using the Investigator Assessment Scale on standardized photographs (0 = no change 1 = mild improvement 2 = moderate improvement and 3 = significant improvement). Good quality clinical photographs were clicked at baseline, 2 months, 3 months, 6 months, and 1 year and were compared for assessment.
Objective and Subjective Clinical Analysis The purpose of this study was to assess both the safety and efficacy of this treatment. This study describes an investigation of Ultherapy for tightening facial skin. Using different transducers, MFU-V treatment can be customized to meet the unique physical characteristics of each patient by adjusting energy and focal depth of the emitted ultrasound. 11, 12Ī commercially available device combines MFU with high-resolution ultrasound imaging (MFU with visualization ), which enables visualization of tissue plane to a depth of 8 mm and allows the user to see where the MFU energy will be applied (Ultherapy Ulthera Inc., Mesa, AZ, USA). The application of heat at these discrete thermal coagulation points cause collagen fibers in the facial planes such as the superficial muscular aponeurotic system (SMAS) and platysma, as well as the deep reticular dermis, to become denatured, contracting and stimulating de novo collagen.

9, 10 The intervening papillary dermal and epidermal layers of skin remain unaffected. Micro-focused ultrasound (MFU) can be focused on subcutaneous tissue where the temperature briefly reaches greater than 60☌, producing small (1 mm 3) thermal coagulation points to a depth of up to 5 mm within the mid-to-deep reticular layer of the dermis and subdermis. During the past decade, IFUS has been used as a clinical noninvasive surgical tool to treat tumors, including those of the liver, prostate, and uterus.
Intense focused ultrasound (IFUS) is an energy modality that propagates through the tissue, up to the depth of several millimeters. 2, 3 Ultrasound has become a leading method, due to its ability to accurately focus energy into the body in the form of heat and selectively destroy small volumes of tissue.
In an effort to meet the patient’s demand of no downtime, many skin tightening procedures and nonablative skin resurfacing treatments have emerged (eg, monopolar, bipolar, tripolar radiofrequency) to induce collagen shrinkage and remodeling, while preserving the epidermis. The concept of replacing a surgeon’s scalpel with noninvasive procedures has attracted attention in medicine for more than half a century.
