AbstractBackgroundWhile the temporal lifting technique has gained increasing attention, there is a dearth of objective and reliable evidence of its effects.AimThe objective of the present study is to analyze the ability of the temporal lifting technique to reduce the midfacial volume by soft tissue repositioning and to achieve an improved pan‐facial appearance by targeting exclusively the subdermal plane of the posterior and superior temple with soft tissue fillers.MethodsA total of 12 patients (1 male and 11 females) with a mean age of 36.75 ± 6.6 years and a mean body mass index of 23.04 ± 1.3 kg/m2 were included in this prospective clinical single‐center interventional study. Injection‐related outcome was evaluated utilizing 3D skin vector displacement and surface volume analyses and scoring based on five different evaluators.ResultsThree months after the treatment, the global esthetic improvement scale rating showed an improved outcome (3.08) when evaluated by the independent observers, very improved outcome when evaluated by the treating physician (4.33), and exceptional improvement when rated by the patient (4.83). Temporal volume improved by 0.36 (P < .001), lower cheek fullness by 0.47 (P < .001), and jawline contouring by 0.51 (P < .001). No major adverse events were reported during the 3‐month observational period.ConclusionObjective outcome measures have provided evidence that by augmenting the posterior superior temple the volume of the middle face can be reduced and the contour of the jawline can be accentuated; this is due to the underlying fascial anatomy and the resulting soft tissue re‐position.

AbstractObjectiveThe most promising facial region for inducing pan‐facial effects is the temporal region. The temple displays signs of facial aging itself which include temporal volume loss and increased visibility of the temporal crest, the temporal vasculature, the lateral orbital rim, and the upper zygomatic arch. The objective of this article is to provide a detailed review of temple anatomy pertaining to routinely performed temporal injection techniques, their expected esthetic outcomes as well as the intendant advantages, disadvantages, and procedure pearls.Materials and MethodsThis narrative review is based on the clinical experience of the authors treating the temporal region for esthetic purposes. The postulated outcome of each technique was observed during the routine clinical practice of the authors.ResultsThe temporal region is based on a bony platform consisting of the parietal, frontal, sphenoid, and temporal bones. The overlying soft tissues are arranged in layers which contain the temporal neurovascular structures. The temporal soft tissues consist of 10 parallel layers which vary in their thickness depending on age‐related influences. Six different techniques will be addressed, which include subdermal and interfascial techniques for volumizing, low and high supraperiosteal techniques for volumizing, and supraauricular and temporal lifting techniques.ConclusionThis narrative provides a detailed anatomic overview of the temporal region and describes each commonly performed injection technique with respect to anatomy, esthetic outcome, as well as potential pearls and pitfalls. It is hoped that the description contained herein may guide esthetic practitioners toward safer and more natural outcomes when treating the face.

Background: Cosmetic treatment of the forehead using neuromodulators is challenging. To avoid adverse events, the underlying anatomy has to be understood and thoughtfully targeted. Clinical observations indicate that eyebrow ptosis can be avoided if neuromodulators are injected in the upper forehead, despite the frontalis muscle being the primary elevator. Methods: Twenty-seven healthy volunteers (11 men and 16 women) with a mean age of 37.5 ± 13.7 years (range, 22 to 73 years) and of diverse ethnicity (14 Caucasians, four African Americans, three Asians, and six of Middle Eastern descent) were enrolled. Skin displacement vector analyses were conducted on maximal frontalis muscle contraction to calculate magnitude and direction of forehead skin movement. Results: In 100 percent of investigated volunteers, a bidirectional movement of the forehead skin was observed: the skin of the lower forehead moved cranially, whereas the skin of the upper forehead moved caudally. Both movements converged at a horizontal forehead line termed the line of convergence, or C-line. The position of the C-line relative to the total height of the forehead was 60.9 ± 10.2 percent in men and 60.6 ± 9.6 percent in women (p = 0.941). Independent of sex, the C-line was located at the second horizontal forehead line when counting from superior to inferior (men, n = 2; women, n = 2). No difference across ethnicities was detected. Conclusions: The identification of the C-line may potentially guide practitioners toward more predictable outcomes for forehead neuromodulator injections. Injections above the C-line could mitigate the risk of neuromodulator-induced brow ptosis.
