Study uses 3D scans to see how well surgery fixes facial asymmetry

Hemifacial atrophy causes one side of the face to shrink, creating an uneven appearance. Surgeons often use fat grafting or free flap reconstruction to restore volume, but it's not clear how much symmetry actually improves. This study looks back at 60 patients treated between 2020 and 2023, using 2D photos and 3D scans to measure changes in facial symmetry at least 6 months after surgery. The goal is to compare which surgical method leads to better symmetry and fewer complications.
