Objectives: It was aimed to clarify the anatomy of the DTF and its surrounding structures based on an examination using ultrasonography, histologic sections, and cadaveric dissection to suggest effective guidelines for thread lifting involving a dual-plane lift based on the anatomic structure.

Introduction: Detailed anatomy of the deep temporal fascia is crucial for selecting the appropriate or most suitable layer to obtain optimal results. However, few studies have investigated important anatomic details that are important during the thread lift procedure. Furthermore, there is a lack of consensus regarding the protocol for effective thread lifting based on anatomic features.

Materials / method: We included 20 healthy young Korean participants. Real-time, two-dimensional, B-mode ultrasonography was performed. Longitudinal scanning was performed along three vertical lines: the line passing through the jugale, the anterior margin of the condylar process of the mandible, and the midpoint between the jugale and anterior margin of the condylar process. Histologic samples from three fresh cadavers were harvested from 2.5 cm above and below the zygomatic arch. 18 fresh adult hemifaces of South Korean cadavers (6males, 3 females) were used to confirm the morphology of deep temporal fascia.

Results: The superficial layer of the deep temporal fascia crossed the zygomatic arch and was connected to the origin of the zygomaticus major muscle at the line passing through the jugale. The superficial layer continued inferiorly to the parotidomasseteric fascia at the line passing through the midpoint and condylar process of the mandible.

Conclusion: This study yielded the novel anatomy of the superficial layer of the deep temporal fascia, and this anatomic structure may be used for an ideal thread lifting procedure.
