Background Fat transfer is the most popular means of gluteal augmentation. However, this procedure may be complicated by pulmonary fat embolisms (PFEs). Of 135 PFEs out of 198,857 cases reported by the Aesthetic Surgery Education and Research Foundation task force, 32 were fatal, contributing to the mortality risk of this procedure being as high as 1:2351. Objectives The aim of this study was to generate an anatomic map of the 3-dimensional location and variability in size of the gluteal region vessels. Methods Twenty cadaveric gluteal regions were dissected. The aorta, venae cavae, popliteal, and saphenous veins were cannulated and injected with colored latex. Dissection was performed subcutaneously, in the gluteus maximus (GM), and submuscularly to evaluate the number and vascular distribution of all the vessels. Vessels were mapped on an XYZ axis. Results The subcutaneous plane, containing 25 vessels on average, had the smallest vessel diameters (artery, 0.9 [0.3] mm; vein, 1.05 [0.22] mm). The GM vein diameter was 1.3 [0.3] mm. Branches of the inferior gluteal vessels had arterial and venous calibers of 2.2 [0.04] mm and 3.5 [0.99] mm, respectively. Superior gluteal artery and vein branches were 1.8 [0.2] mm and 3.85 [1.9] mm in diameter, respectively. Superior and inferior gluteal vein diameters were 7.61 [2.24] mm and 13.65 [6.55] mm, respectively. Conclusions The deeper and more medial planes of the gluteal region house larger, more prominent vessels. This research objectifies and is consistent with recommendations made by various recent task force reports to limit fat transfer to the subcutaneous plane.

Background The anterior or submental necklift has been well described. Long-term results have been demonstrated in patients with minimal, mild, and moderate skin excess. It relies on the skin’s unique ability to contract once separated from its attachments and further enhances the surgical result with treatment of the intermediate layer- subplatysmal fat, anterior digastric, submandibular gland, and platysma. Treatment of this layer differentiates this operation from liposuction and offers benefits beyond liposuction alone. Objectives The authors sought to assess the long-term success of the anterior necklift for neck rejuvenation and determine its utility in patients with severe cervicomental angles. Methods This was a single-surgeon, retrospective review of patients who underwent an isolated anterior necklift with no additional procedures between 1998 and 2017. Pre- and postprocedure photographs were scrambled and examined by independent evaluators grading the change in cervicomental angle based on the Knize scale. The reduction in apparent age was calculated utilizing the validated apparent age assessment scale. Results Twenty-seven patients were evaluated (42% mild and 58% moderate to severe necks preoperatively). The average follow-up was 24.7 months. There was an average 3.6-year age reduction and 1.0-grade improvement in all patients. In moderate to severe necks, there was a 3.9-year age reduction and 1.4-grade improvement in the cervicomental angle following surgery. Conclusions This study demonstrates the effectiveness of the operation in improving the cervicomental angle and reducing the overall apparent age of patients, even more so in severe cases. The operation is an option for patients who desire neck improvement but are unwilling to undergo a facelift. Level of Evidence: 4
