Facial aging involves changes in the facial skeleton and soft tissues. There is limited quantitative data on soft tissue aging of the face.
Magnetic resonance imaging (MRI) was used to quantify and compare facial soft tissue loss over time.
Two thousand thirty-seven MRI scans from 58 women divided into young, middle-aged, and older groups were screened. A blinded radiologist used MRI to measure the temporal, infraorbital, and medial and lateral cheek areas.
The mean thickness of the subcutaneous tissue in the temporal area was 12.3, 8.4, and 8.9 mm in the young, middle-aged, and older groups, respectively (p < .001). A mean difference of 1.6 mm was seen between the young and middle-aged groups and 2.2 mm between the young and older group (p < .001) in the infraorbital area, 3.3 mm between the young and middle-aged groups and 3.2 mm between the young and older group in the medial cheeks (p < .001), and 2.4 mm between the young and middle-aged groups and 2.4 mm between the young and older group in the lateral cheeks (p = .01).
Facial soft tissue undergoes significant deterioration over time, with the most dramatic changes between the ages of 30 and 60 in the temporal, infraorbital, and lateral and medial cheek areas. Soft tissue augmentation and volume correction in these areas may be an effective strategy for facial rejuvenation.
面部衰老涉及面颅骨和软组织的变化。关于面部软组织衰老的定量数据有限。
磁共振成像(MRI)用于定量和比较随时间推移的面部软组织丢失。
对 58 名女性的 2037 份 MRI 扫描进行了筛选,这些女性分为年轻、中年和老年组。一位盲法放射科医生使用 MRI 测量颞部、眶下、内侧和外侧面颊区域。
颞部皮下组织的平均厚度分别为年轻组 12.3mm、中年组 8.4mm 和老年组 8.9mm(p<0.001)。在眶下区域,年轻组和中年组之间的平均差异为 1.6mm,年轻组和老年组之间的差异为 2.2mm(p<0.001),在颊内侧,年轻组和中年组之间的平均差异为 3.3mm,年轻组和老年组之间的差异为 3.2mm(p<0.001),在颊外侧,年轻组和中年组之间的平均差异为 2.4mm,年轻组和老年组之间的差异为 2.4mm(p=0.01)。
面部软组织随时间显著恶化,颞部、眶下、外侧和内侧颊区在 30 至 60 岁之间变化最明显。在这些区域进行软组织填充和体积矫正可能是面部年轻化的有效策略。
