Current techniques for temple volumization primarily focus on deep or superficial targets. Further anatomical exploration of intermediate injection targets is warranted.
The purpose of this study was to examine the anatomy of the intermediate temporal fat pad (ITFP) as it relates to filler injection procedures and to explore the utilization of ultrasound technology for clinical localization.
Ultrasound technology was utilized to identify and inject red dyed hyaluronic acid filler into the ITFP in 20 hemifacial fresh cadavers. Cross-sectional dissection was performed to confirm injection accuracy and document pertinent anatomical relationships. The same technique was performed in a single clinical patient case employing ultrasound guidance and injectable saline.
The ITFP is a quadrangular structure located in the anterior-inferior bony trough. The ITFP is supplied by a middle temporal artery branch and encased between the superficial and deep layers of deep temporal fascia. In 18 of 20 (90%) injections performed under ultrasound guidance, the injected product was accurately delivered to the substance of the ITFP, and in 2 of 20 (10%), the product was found immediately below the deep layer of deep temporal fascia within the temporalis muscle. In the single clinical case, saline was successfully injected in the ITFP under ultrasound guidance.
The ITFP is a consistent anatomical structure in the anterior-inferior trough of the temporal fossa. Ultrasound technology can be utilized to identify and inject the fat pad. Further clinical evaluation will determine the role of this fat pad as a potential intermediate injection target for temple volumization procedures.
目前，用于太阳穴容积增大的技术主要集中在深部或浅部目标。有必要进一步探索中间注射目标的解剖结构。
本研究旨在研究中间颞部脂肪垫（ITFP）的解剖结构与填充物注射程序的关系，并探索超声技术在临床定位中的应用。
在 20 具半面新鲜尸体中，利用超声技术识别并注射红色标记的透明质酸填充剂到 ITFP 中。进行横断面解剖以确认注射的准确性并记录相关的解剖关系。在单个临床患者病例中，采用超声引导和可注射生理盐水重复了相同的技术。
ITFP 是一个位于前下方骨槽的四边形结构。ITFP 由颞中动脉分支供应，并被深颞筋膜的浅层和深层包裹。在 20 次超声引导下的注射中，有 18 次（90%）准确地将注射产品输送到 ITFP 的实质内，而在 20 次中有 2 次（10%）发现产品位于颞肌内深颞筋膜深层下方。在单个临床病例中，在超声引导下成功地将生理盐水注入 ITFP。
ITFP 是颞窝前下方槽中的一个一致的解剖结构。超声技术可用于识别和注射脂肪垫。进一步的临床评估将确定该脂肪垫作为太阳穴容积增大程序的潜在中间注射目标的作用。
