The aim of this study was to determine the anatomical features of the deep temporal arteries (DTAs) and thereby provide clinical information for the temple augmentation procedure. Forty-two adult hemifaces from 15 Korean and 6 Thai cadavers (12 males, 9 females; mean age at death, 79.6 years) with no history of trauma or surgical procedure on the temple area were used for anatomical study. A detailed dissection was performed to identify the locations of the anterior and posterior deep temporal arteries (ADTA and PDTA) with reference to the vertical plane passing through the zygomatic tubercle. Fifty-eight healthy Korean participants (31 males and 27 females; mean age, 24.7 years) were included in the ultrasonographic study. The distance from the bone to the DTAs was measured at the level of the zygomatic tubercle (HZt ) and the eyebrow (HEb ). The DTAs were not found within 7.2-12.6 mm posterior to the zygomatic tubercle; instead, the locations varied widely at the HEb . The distances between the bone and the ADTA were 1.7 ± 1.2 mm (mean ± SD) and 1.3 ± 0.8 mm, and those between the bone and the PDTA were 2.1 ± 1.2 mm and 2.0 ± 1.4 mm at HZt and HEb , respectively. Our findings indicate that at HZt , the area 1 cm posterior to the zygomatic tubercle may be a safe area for deep temple augmentation procedures. However, because the distribution patterns of the DTAs at HEb and depth of the DTAs are variable, additional care is required to minimize the risks of the procedure.

Autologous lipotransfer aims to restore aging-associated volume loss, but with low predictability owing to 20-90% first-year loss of transferred fat. Enrichment by adipose-derived stem cells within the stromal vascular fraction (SVF) aims to improve volume retention through their differentiation potential and paracrine actions exerted by secreted trophic and angiogenic factors. Assessing studies lacked split-face designs, and used multitudes of enrichment ratios, preparation techniques and evaluation methods ending in contradictory reports regarding enrichment advantage.
To test whether enriching the autologous fat graft with SVF will increase its residual volume as compared to non-enriched graft. A standardized enrichment protocol and ratio and objective assessment were employed.
In a split-face design, and after random assignment, bilateral temple augmentation using non-enriched versus SVF-enriched autologous lipotransfer were compared in middle-aged females otherwise healthy non-pregnant or breast-feeding females abstaining from esthetic or weight-controlling procedures. Temple volume scale (TVS), skin layers\' thickness measured by ultrasound biomicroscopy (UBM), visual analog scale for patients\' satisfaction, and side effects were blindly assessed at 1 week, 3 months, and 6 months.
In the included 15 females, TVS was significantly lower (0.5 ± 0.5 versus 1.1 ± 0.7, P = 0.0001), and% hypodermal augmentation was significantly higher (70.92 ± 58.09 versus 18.93 ± 19.33, P = 0.001) on the SVF-enriched side at 6 months. Patient satisfaction was similar bilaterally (P = 1), as were sequelae frequencies as lumping, edema, and ecchymosis.
SVF enrichment of transferred fat significantly improved its residual volume at 6 months; a conclusion that needs further validation. UBM was an informative objective tool for the following temple skin thickness changes. Trial registration clinical trials.gov (NCT03965936).

When evaluating the face in thirds, the upper face, midface, and lower face, one may assume the lateral the temple, midface, and lateral mandible as the pillars of these subdivisions. Many of our facial aesthetic procedures address these regions, including the lateral brow lift, midface lift, and lateral face lift. As the use of facial fillers has advanced, more emphasis is placed on the correction of the temples, midlateral face, and lateral jaw line. This article is dedicated to these facial aesthetic pillars.
