Ultrasonographic Patterns of Calcium Hydroxyapatite According to Dilution and Mix With Hyaluronic Acid.

Objectives: To assess the ultrasonographic patterns of different calcium hydroxyapatite (CaHA) formulations, including the undiluted, diluted, and mixed with hyaluronic acid (HA) compounds.

Methods: To review the ultrasonographic images of patients ≥18 years with confirmed injections of CaHA clinically and ultrasonographically, and without different concomitant types of fillers in the same region or other systemic or localized cutaneous diseases.

Results: Twenty-one patients met the criteria (90% female; 10% male; mean age: 52 years ± 12.

Ultrasound Morphology of Polycaprolactone Filler.

Nowadays, cosmetic fillers are widely used and the reports of complications are rising. Therefore, the possibility to detect and identify noninvasively new fillers can provide a potent tool for managing complications. The objective of this study was to assess the ultrasound morphology of polycaprolactone.

Melanocytes and keratinocytes transfer using sandpaper technique combined with dermabrasion for stable vitiligo.

Background: Surgery is currently the most successful approach for difficult cases of vitiligo. The efficacy of epidermal surface removal (dermabrasion) is near 50%, and the efficacy of grafts is 70%.

Objective: To evaluate the efficacy and safety of a combined approach using dermabrasion and grafting for unresponsive vitiligo.
