Background: Recent anatomical findings have suggested that facial fat distribution is complex and changes with age. Here, the authors developed a grafting technique based on the physiologic distribution and volume changes of facial fat compartments to achieve a youthful and natural-appearing face.

 

Methods: Forty cadaveric hemifaces were used for the dissection of fat compartments and neurovascular structures in the midface area. Seventy-eight patients were treated for cheek atrophy using the authors’ targeted restoration of midface fat compartment volume. The outcome was evaluated by a two-dimensional assessment, malar lipoatrophy assessment, and a satisfaction survey.

 

Results: The medial and lateral parts of the deep medial cheek fat compartment were separated by a septum arising from the lateral border of the levator anguli oris muscle. The angular vein traveled between the deep medial cheek fat compartment and the buccal fat pad, 12 mm from the maxilla. A total volume of 29.3 ml of fat was grafted per cheek for each patient. A 12-month follow-up revealed an average volume augmentation rate of 27.1 percent. Pleasing and elevated anterior projection of the cheek and ameliorated nasolabial groove were still obvious by 12 months after the procedure. In total, 95.2 percent of the patients were satisfied with their results.

 

Conclusions: The present study provides the anatomical and clinical basis for the concept of compartmentally based fat grafting. It allows for the restoration of facial fat volume close to the physiologic state. With this procedure, a natural and youthful facial contour could be rebuilt with a high satisfaction rate.

 

背景:最近的解剖学发现表明,面部脂肪分布是复杂的,并且随着年龄的变化而变化。在这里,作者开发了一种基于面部脂肪室的生理分布和体积变化的移植技术,以获得年轻而自然的面容。

 

方法:在40侧身体半面标本上解剖面中部脂肪区和神经血管结构。78名患者接受了面颊萎缩的治疗,使用的是作者提出的面中部脂肪腔体积的有针对性的恢复。结果通过二维评估、颧部脂肪萎缩评估和满意度调查进行评估。

 

结果:颊深内侧脂肪室的内侧部和外侧部分由口提肌外侧缘起的隔隔区隔开,内侧脂肪室的内侧部和外侧部由口上提肌外侧缘形成的隔膜隔开。角状静脉走行于颊深内侧脂肪室与颊脂垫之间,距上颌12 mm。每个患者的每个脸颊总共移植了29.3毫升的脂肪。12个月的随访显示,平均音量扩大率为27.1%。术后12个月,面颊前投影满意、隆起,鼻唇沟改善仍明显。总体而言,95.2%的患者对结果感到满意。

 

结论:本研究为间隔式脂肪移植的概念提供了解剖学和临床依据。它可以使面部脂肪体积恢复到接近生理状态。通过这一过程,可以重建自然而年轻的面部轮廓,并获得较高的满意率。
