ment vectors using Vectra software with VAM module.
Results: Esthetic outcome was rated by an independent professional observer and
by the patient immediately after the treatment (76.67% ± 17.6% vs
66.67% ± 18.1%) (P = 0.001) and after 1 month (80.00% ± 14.0% vs
75.00% ± 21.1%) (P = 0.19). Skin laxity, subcision, and the application of more than
1.0 cc per side resulted in our experimental setting in a smaller magnitude of skin
displacement vectors indicating a reduced lifting effect.
Conclusion: The posterior temporal supraSMAS minimally invasive lifting procedure
seems to be a valid technique to treat temporal volume loss and to reduce the signs
of age‐related changes in the middle and lower face, ie “marionett line” and jowl
deformity.
