Abstract
Background
Current techniques for temple volumization primarily focus on deep or superficial targets. Further anatomical exploration of intermediate injection targets is warranted.
Objectives
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.
Methods
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.
Results
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.
Conclusions
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.
