RESUMEN
BACKGROUND: Micro-focused ultrasound with visualization has been cleared by the United States Food and Drug Administration to noninvasively lift the eyebrow, lift submental and neck tissue, and improve lines and wrinkles of the décolleté. OBJECTIVE: The objective of this prospective, open-label pilot study was to evaluate the efficacy and safety of patient-specific, customized micro-focused ultrasound with visualization treatment with vertical vectoring to lift and tighten facial and neck tissue. METHODS AND MATERIALS: Subjects 25 to 60 years of age (N=20) with areas of skin laxity on the face and neck were enrolled and treated. A dual depth treatment was administered using a vectored pattern. Subjects were evaluated after 90 days, 180 days, and one year. RESULTS: Overall improvements in Subject Global Aesthetic Improvement Scale and Physician Global Aesthetic Improvement Scale scores were reported by 90 and 100 percent of subjects at 90 and 180 days, respectively, and 95 percent for both measures at one year. Six of 14 evaluable subjects were rated as improved by blinded assessment at one year. Self-reported improvements maintained for up to one year included less sagging (79%), fewer lines and wrinkles (58%), and smoother skin texture (47%). CONCLUSION: Based on these results, treatment with micro-focused ultrasound with visualization with vertical vectoring demonstrated appreciable lifting and tightening of facial and neck tissue resulting in improved Global Aesthetic Improvement Scale scores and a high degree of patient satisfaction for up to one year.
