- Brief Summary
Skin aging is a continuous and inevitable presses usually starting at the age of mid-twenties, this prosses affects all facial layers including skin, subcutaneous fat, superficial muscular aponeurotic system (SMAS), deep facia, the retaining ligaments, muscle activity, and even facial bony structure . The clinical outcome of this process causes the aging signs of the face and neck, including loose facial skin, sagging cheeks, excess skin hanging from the lower jawline and excess fat in the neck .
In the last decade with the introduction of absorbable threads, thread lifting has gained interest and popularity among patients and physicians, as noninvasive technique to treat ptotic skin and reposition of ptotic soft tissue into a more anatomical direction. Histopathological studies indicated that dermal and subcutaneous foreign body reaction after inserting the threads, in forms of collagen deposition, and fibrosis , could explain the tightening effect throughout contracture and remodeling. However, some studies question efficacy especially in the aspects of durability and patient satisfaction .
Another nonsurgical alternative for facial rejuvenation is high-intensity focused ultrasound (HIFU) therapy, during the past decade, HIFU has been used as a clinical noninvasive surgical tool to treat tumors, including those of the liver, prostate, and uterus (10-12) The HIFU devices heat tissue with acoustic energy in a focused, controlled manner. The thermal injury within the tissue leads to focal necrosis and cellular damage, initiating an inflammatory cascade that culminates in tissue remodeling, similar to changes that occur after ablative or nonablative laser treatments .
The Investigators hypothesis that the HIFU treatment followed immediately by thread insertion can amplify and enhance the skin fibrosis, tissue lifting capacity and might give better and longer clinical results in treating ptotic skin.

- Primary Outcome Measures
Name Time Method Change in Subject Global Aesthetic Improvement Scale from baseline to 6 months, and 12 months after treatment for each side of the face. 3, 6 months and 12 months after treatment Subject Global Aesthetic Improvement Scale (SGAIS): (0 = no change; 1 = mild changes; 2 = moderate changes; 3 = significant changes)
Skin lifting in upper, mid and lower part of the face: 3, 6 months and 12 months after treatment for each side of the face 3, 6 months and 12 months after treatment For assessment of skin lifting, the face will be devided into three segmnets : upper, mid, and lower third. The mid-third face-lift will be evaluated by mid-cheek angle. The lower third face-lift will be evaluated by submental lift. The mid-cheek angle will the angle between a horizontal line drawn from alae nasi and a line drawn from alae nasi to the malar prominence.
Change in Investigator Global Aesthetic Improvement Scale from baseline to 6 months, and 12 months after treatment for each side of the face 3, 6 months and 12 months after treatment Investigator Global Aesthetic Improvement Scale (IGAIS) from the standardized photographs (0 = no change; 1 = mild improvement; 2 = moderate improve- ment; and 3 = significant improvement)
Wrinkle score, Texture score and pore score calculated by VISIA Software 3, 6 months and 12 months after treatment for each side of the face 3, 6 months
- Secondary Outcome Measures
Name Time Method Occurrence of treatment-related adverse effects collected during the treatment and follow-up periods. 12 months including pain, nerve irritation , numbness/paresthesia , lumps , erythema, tingling, swelling , headache , rash, and pruritus
Patients pain sensation during the treatment for each side of the face at the first visit 1 month Visual Analogue Scale (VAS) (0-10), with 0 denoting no sensation and 10 denoting the worst possible pain.
