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.
自体脂肪移植是一种用于矫正体积缺陷、萎缩和硬化的外科手术。三维（3D）面部摄影可以使研究人员通过体积和表面评估来量化外科手术的成功率。作者使用3D摄影评估了一名15岁患有帕里-罗姆伯格综合征患者的自体脂肪移植结果，该罕见病症会导致皮肤、皮下组织最终骨骼的进行性半侧面部萎缩。在手术干预前和术后4个月进行了立体摄影测量采集。通过计算治疗侧与健康侧之间点对点距离的均方根偏差以及术前和术后3D面部扫描之间的体积变化，对面部对称性方面的所得结果进行了客观评估。术后4个月，73%的注射脂肪组织被吸收，而面部对称性提高了63%。所提出的方法是非侵入性的，并提供了有关手术和美学结果的定量信息。临床医生可以更好地规划手术，患者也可以更积极主动并配合治疗。
