Hereby, we objectively assessed the outcomes of a facial-lifting procedure with Botulinum toxin type A (BoNT-A) using a 3D stereophotogrammetry quantification (3D-SQ). A 46-year-old female patient received a full face BoNT-A treatment in a total dose of 180 Speywood Units (sU). Frontal, lateral and oblique photographs were taken before and 20 days after treatment, at rest and during mimic movements. Also, a facial scanning was performed before and 20 days after BoNT-A injections. The results were analyzed using a 3D-SQ software. The photographs showed a decrease in expression lines and dynamic wrinkles. In addition, a better-defined jawline and volume gain in the midface area with improvement of the profile appearance, due to the reduction of the sagging skin under the chin, was observed. The 3D-SQ showed volume gains of 1.17 ml on the right and of 1.59 ml on the left cheekbone areas, due to the cranially soft-tissue repositioning. In addition, a decrease in the volume of melomental folds areas (0.27ml on the right and 0.41 ml on the left side) was reported, compatible to the above-mentioned volume gain. Measurements considering cephalometric points showed a decrease in the total facial height (distance from Trichion to Mental points), suggesting a soft tissue dislocation in an upward direction. Finally, this case report showed quantitative results that can evidence the role of BoNT-A in faciallifting procedures. These results reinforce the importance of using a 3D-SQ to assess the outcomes of BoNT-A and, probably, other aesthetic procedures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
