Abstract
BACKGROUND: Hyaluronic acid (HA) filler injection is easy and effective for augmenting the temple. However, there are multiple layers in the temple and multiple guidelines regarding the optimal layer for administering these fillers. In this study, we used ultrasonography to reveal relatively safe layers for augmenting the temple and selected the space between the superficial temporal fascia (STF) and deep temporal fascia (DTF) as an injection site. METHODS: Doppler ultrasonography was used to differentiate anatomic layers of the temple and detect the blood vessels. HA filler was injected in the space between the STF and DTF. After filler injection, ultrasonography was used to detect the proper filler location. Patient satisfaction and complications were evaluated. RESULTS: Hyaluronic acid filler was injected into the space between the STF and DTF in all patients. An average of 1.08 ml of HA filler was injected into one side of the temple. In 15 out of 50 patients, the frontal branch of the superficial temporal artery was detected at the hairline or on the anterior side of the hairline, which was the location where the temple augmentation was performed. Forty-nine patients were satisfied with the results after 3 months postoperatively. No serious complications were observed. CONCLUSIONS: Hyaluronic acid filler injection in the space between the STF and DTF is a relatively safe and easy site for temple augmentation.
