Dynamic ultrasound evaluation of body fillers and biostimulators in the buttocks of fresh-frozen specimen.

BACKGROUND: Ultrasound imaging is a useful tool to study the injection of fillers and biostimulators in the body. OBJECTIVE: Sonographically evaluate real-time injections of fillers and biostimulators and describe their behavior in the subcutaneous tissue of the buttocks of fresh-frozen specimen. METHODS: injection of two brands of high-density hyaluronic acid (HA), one brand of calcium hydroxyapatite (CaHA), one brand of hybrid injectable (CaHa + HA), one brand of polycaprolactone (PCL) and three brands of poly-l-lactic acid (PLLA) were performed in the subcutaneous tissue of the gluteal region under ultrasonography visualization on a fresh-frozen specimen. Videos during injection and static images immediately after injection were obtained. The sonographic aspects of the substances and their dispersion and interaction with the surrounding tissues were described. RESULTS: Real-time ultrasound showed different dispersion patterns of the two brands of HA, CaHA, hybrid injectable (CaHa + HA) and the three brands of PLLA. The sonographic aspects among the brands of PLLA were also different. CONCLUSIONS: The dynamic ultrasound evaluation of the injection of HA, CaHA, hybrid injectable (CaHa + HA), PCL and PLLA in a fresh-frozen specimen shed some light on their aspects and dispersion pattern in the buttock. If these patterns are confirmed in further studies in vivo, there will be a positive impact on the selection and development of safer and more effective techniques to enhance buttock contour.

LL body contour technique-A new way of gluteal contouring and augmentation with hyaluronic acid filler.

INTRODUCTION: Enhancing and altering body contours has increasingly been the focus of new technologies and techniques in aesthetic treatments. The buttocks are seen as a symbol of beauty, sensuality, and attraction. PATIENTS AND METHODS: The authors described a technique for female and male gluteal augmentation. It uses a special marking, a safe plan, and a specific product. The patients chosen for this technique wanted to have an augmentation or projection effect on the buttocks, but were not willing to undergo surgery. The product used was Sofiderm Subskin Aeskins. The plan of injection was the subcutaneous as no major blood vessels were found. RESULTS: The authors report good aesthetic results with the proposed technique. The patients reported a high degree of satisfaction. DISCUSSION: The product chosen has a high G prime and a larger molecule size, which accounts for resistance to deformation and a high lifting power. Thus, result can be visible in a large body area. As the anatomy between male and female buttocks are different, different techniques were used for each gender. CONCLUSION: The LL body contour technique for gluteal augmentation proved to be a minimally invasive technique, with quick results, without major risks and downtime.

Cutis laxa: Improvement of facial aesthetics by using botulinum toxin.

BACKGROUND: Cutis laxa is characterized by the total loss of skin elasticity, which is also called generalized elastosis that leads to the appearance of early aging. OBJECTIVE: The authors report a patient with cutis laxa in which botulinum toxin was used for the improvement of facial aesthetics. This is a case report with a literature review. Botulinum toxin was injected into the classical sites usually used for the treatment of dynamic wrinkles. RESULTS: The patient showed improvement of the aging appearance. CONCLUSION: The use of botulinum toxin may represent an additional, less invasive resource to improve facial defects in these patients.
