Volume restoration is no more a fresh theory for midfacial rejuvenation. However, lack of knowledge regarding the natural ageing process of fat compartments often leads to an insufficient or excessive clinical result. The aim of this study is to reveal the age-related changes in midfacial fat compartments and the correlation between midfacial grooves and the related fat compartments.
This study included 60 Asian females in defined age-based categories. The thickness of the infraorbital fat compartment, the nasolabial fat compartment, and the cheek fat compartments were measured using computed tomography (CT) images. Analysis of correlations between midfacial grooves and the related fat compartments was performed using the SPSS software.
A tendency of thickening in the infraorbital fat and nasolabial fat compartments with age was observed. The superficial layer of cheek fat compartments was found to be thinner, and a similar tendency was observed in the medial part of deep medial cheek fat. However, it was thicker in the lateral part of deep medial cheek fat. There was a negative correlation between the fat thickness of deep medial cheek fat and both the severity of tear trough deformity and the nasolabial fold. A positive correlation between the lower third of the nasolabial fat compartment and the severity of the nasolabial fold was found as well.
Different midfacial fat compartments tended to undergo selective hypertrophy or atrophy with ageing. The findings of this study suggested that augmentation of the deflated fat compartment and liposuction of the hypertrophic fat compartment can provide a more natural effect in facial rejuvenation.
容积恢复已不再是一种用于中面部年轻化的全新理论。然而，对于脂肪间隔自然衰老过程缺乏了解常常导致临床效果不足或过度。本研究的目的是揭示中面部脂肪间隔与年龄相关的变化以及中面部沟纹与相关脂肪间隔之间的相关性。
本研究纳入了60名按年龄分组的亚洲女性。使用计算机断层扫描（CT）图像测量眶下脂肪间隔、鼻唇脂肪间隔和颊部脂肪间隔的厚度。使用SPSS软件对中面部沟纹与相关脂肪间隔之间的相关性进行分析。
观察到眶下脂肪和鼻唇脂肪间隔随年龄增长有增厚的趋势。发现颊部脂肪间隔的表层较薄，在内侧深层颊脂肪的内侧部分也观察到类似趋势。然而，在深层内侧颊脂肪的外侧部分较厚。深层内侧颊脂肪的厚度与泪沟畸形的严重程度和鼻唇沟均呈负相关。还发现鼻唇脂肪间隔的下三分之一与鼻唇沟的严重程度呈正相关。
不同的中面部脂肪间隔随着年龄增长往往会发生选择性肥大或萎缩。本研究结果表明，对萎缩的脂肪间隔进行填充以及对肥大的脂肪间隔进行抽脂在面部年轻化中可以提供更自然的效果。
