Successful aesthetic interventions in upper-face aging require a profound understanding of the intricate anatomy of temporal. This study aimed to comprehensively evaluate the effect of hyaluronic acid (HA) injection in temple areas by combining quantitative analysis with detailed anatomical insights.
Twenty-five women received HA injections for temple hollowness. The injections targeted the interfacial layer between superficial and deep temporal fascia. Three-dimensional scanning, hollowness examination, and sonographic measurements were conducted 3 and 6 months postprocedure.
Sonography identified 17 soft tissue layers in the temple, each with distinct characteristics. The notable layers include the epidermis, dermis, superficial and deep temporal fasciae, innominate fasciae, and superficial and deep temporal fat compartments. Three-dimensional volume was 0.86 mL at 3 months and 0.72 mL at 6 months. The average thickness of HA was 3.82 mm (immediately), 3.00 mm (3 mo), and 2.51 mm (6 mo). The depression on the temple was 4.33 mm (preprocedure), 0.71 mm (3 mo), and 1.62 mm (6 mo). The grade improved by 2.41 and 1.74 levels at 3 and 6 months.
Identifying detailed superficial and deep layers of the deep temporal fascia challenged traditional descriptions, with detailed dividing of superficial and deep temporal fascia in sonography. Innominate fascia was also distinguished. This study provided a comprehensive evaluation of the effects of HA injections in temple areas. Precise anatomical insights and quantitative assessments contribute to a deeper understanding of the structural changes induced by this procedure. Sonography is valuable for delineating distinct layers and guiding aesthetic interventions in the temporal region.
对上脸衰老进行成功的美容干预需要对颞部复杂的解剖结构有深入的了解。本研究旨在通过定量分析与详细的解剖学见解相结合，全面评估透明质酸（HA）注射到颞部区域的效果。
25名女性接受了HA注射以改善颞部凹陷。注射部位为颞浅筋膜和颞深筋膜之间的界面层。在术后3个月和6个月进行三维扫描、凹陷检查和超声测量。
超声检查发现颞部有17层软组织，每层都有不同的特征。值得注意的层包括表皮、真皮、颞浅筋膜和颞深筋膜、无名筋膜以及颞浅脂肪层和颞深脂肪层。三维体积在3个月时为0.86 mL，在6个月时为0.72 mL。HA的平均厚度分别为即时3.82 mm、3个月时3.00 mm和6个月时2.51 mm。颞部凹陷术前为4.33 mm、3个月时为0.71 mm、6个月时为1.62 mm。分级在3个月和6个月时分别改善了2.41级和1.74级。
确定颞深筋膜的详细浅层和深层挑战了传统描述，超声检查对颞浅筋膜和颞深筋膜进行了详细划分。无名筋膜也得以区分。本研究对HA注射到颞部区域的效果进行了全面评估。精确的解剖学见解和定量评估有助于更深入地了解该手术引起的结构变化。超声检查对于描绘不同层次和指导颞部区域的美容干预具有重要价值。
