High-Frequency Ultrasound-Guided Temporal Fat Transplantation: A Safe and Visualized Approach.

ABSTRACT

SUMMARY: Autologous fat injection is one of the most popular methods for the treatment of temporal depression; however, accurate puncture into the target layer without vascular compromise is hard to achieve. With the aid of high-frequency ultrasonography, the authors performed autologous fat transplantation after visualization in five cases, with satisfactory results. The authors observed the course of superficial temporal vessels, the orbitozygomatic artery, and sentinel veins preoperatively, and used high-frequency ultrasonography to guide lipotransfer into the desired layer intraoperatively, to avoid intravascular injection. With the aid of high-frequency ultrasonography, the authors can easily prevent vascular complications and personalize surgical procedures, as anatomical variations of vasculature can also be detected by means of this method.
