Clinical Studies

Autologous fat grafting is a surgical procedure used to correct volumetric defects, atrophies, and sclerosis. Three-dimensional (3D) facial photography may enable researchers to quantify the success of surgical procedures through volumetric and surface assessments. Using 3D photography, the authors assessed the results of autologous fat grafting performed in a 15-year-old patient affected by Parry-Romberg syndrome, a rare condition resulting in progressive hemifacial atrophy of skin, subcutaneous tissues and, ultimately, bone. Stereophotogrammetric acquisitions were performed before and 4 months after the surgical intervention. The obtained results were objectively assessed in terms of facial symmetry through calculation of root mean square deviation point-to-point distance between the treated and healthy side, and volume modifications between pre- and postsurgical 3D facial scans. Four months after surgery, 73% of injected adipose tissue was resorbed, whereas facial symmetry increased up to 63%. The proposed method is not invasive and provides quantitative information about the surgical and esthetic outcomes. Clinicians could better plan surgery, and the patients could be more motivated and compliant to the treatment.
