Background Botulinum toxin-A (BTX-A) injection of regional platysma has been utilized in the lower-part elevation and mandibular contour sculpture. However, the relative research, especially in quantitative assessment appears very spare. Our aim is to investigate the efficacy of three-dimensional (3D) technology as a method for regional platysma injection with BTX-A. @@@ Materials and Methods From October 2019 to September 2020, patients with mild or moderate degrees of facial sagging on the lower face were recruited to regional platysma BTX-A injection, and 3D scanning and measurement technology was used to evaluate the difference of curved distances and angels. Patients' improvement was assessed by the global aesthetic improvement scale (GAIS). @@@ Results A total of 57 patients underwent regional platysma BTX-A injection and 32 patients were followed up successfully. Compared with Pre-operative, postoperative facial reference curves distance and cervico-mental angles had statistical differences (p < 0.05). GAIS suggested that the 3D imaging measurement technology could improve satisfaction. @@@ Conclusion 3D technology can evaluate the improvement of the lower face with BTX-A. It provides effective measurement methods and raises satisfaction.
