Since 2007, when the anatomy of facial fat compartment was described, an increasing number of studies on the aging process of the compartment of cadavers has emerged.
The authors evaluated the aging changes of lateral facial fat compartments on the same person.
Sixty-three patients were included in this retrospective study. All patients had magnetic resonance imaging scans with at least 4 years apart. The authors targeted the fat compartments of the superficial temporal, subcutaneous temporal, and buccal fat pad, comparing the data on different time points.
The thickness of the subcutaneous temporal fat did not change significantly. The 3 diameters of the superficial temporal fat compartment all became thinner on the axial view (P < 0.05). On the sagittal view, the superficial temporal fat elongated from 38.89 mm to 43.74 mm (P < 0.05). The buccal fat compartment also lengthened from 68.73 mm to 74.39 mm (P < 0.05) and had a positive correlation with follow-up duration only.
The study revealed the fat compartment change on the same person with time. The temporal hollow mainly originates from the thinner part of the superficial temporal fat. The descending of the buccal fat pad aggravates the labiomandibular fold. By understanding the aging process more fully, we can rejuvenate our patients more naturally.
自 2007 年面部脂肪解剖描述以来，越来越多的关于尸体脂肪隔室老化过程的研究出现。
作者评估了同一人侧面部脂肪隔室的老化变化。
本回顾性研究纳入了 63 例患者。所有患者均接受了至少相隔 4 年的磁共振成像扫描。作者针对颞浅脂肪、颞浅皮下脂肪和颊脂垫的脂肪隔室进行了研究，比较了不同时间点的数据。
颞浅皮下脂肪的厚度没有明显变化。颞浅脂肪隔室的 3 个直径在轴位视图上均变薄（P < 0.05）。在矢状视图上，颞浅脂肪从 38.89 毫米延长到 43.74 毫米（P < 0.05）。颊脂垫也从 68.73 毫米延长到 74.39 毫米（P < 0.05），并且仅与随访时间呈正相关。
该研究揭示了同一人随时间的脂肪隔室变化。颞部凹陷主要源于颞浅脂肪变薄的部分。颊脂垫的下降加重了唇下颌皱襞。通过更全面地了解老化过程，我们可以更自然地使患者年轻化。
