3D stereophotogrammetry quantification for tissue repositioning using Botulinum toxin A: a case report

Hereby, we objectively assessed the outcomes of a facial-lifting procedure with Botulinum toxin type A (BoNT-A)using 3D stereophotogrammetry quantification (3D-SQ). 46-year-old female patient received full faceBoNT-A treatment in total dose 180 Speywood Units (sU). Frontal, lateral and oblique photographs weretaken before 20 days after treatment, at rest during mimic movements. Also, facial scanning wasperformed BoNT-A injections. The results were analyzed using 3D-SQ software. Thephotographs showed decrease expression lines dynamic wrinkles. In addition, better-defined jawlineand volume gain midface area improvement profile appearance, due to reduction thesagging skin under chin, was observed. gains 1.17 ml on right of1.59 left cheekbone areas, cranially soft-tissue repositioning. thevolume melomental folds areas (0.27ml 0.41 side) reported, compatibleto above-mentioned gain. Measurements considering cephalometric points thetotal height (distance from Trichion Mental points), suggesting soft tissue dislocation an upwarddirection. Finally, this case report quantitative that can evidence role facialliftingprocedures. These reinforce importance assess BoNT-Aand, probably, other aesthetic procedures.
