“…Moreover, the use of a cannula does not preclude intravascular filler embolization; therefore, a complete understanding of the facial anatomy is mandatory because a filler can be injected into the blood vessels while using a cannula. 38 , 39 …”

Background: Beauty standards vary by race and region, which must be accounted for in creating beauty. Chinese have unique features, including a depressed nose, flat midface, and small chin, and have different cosmetic concerns. We performed a consensus study on filler injections based on the Chinese standard of beauty due to a lack of such study. Methods: We organized the YVOIRE Consensus Group, including 5 plastic surgeons. We discussed common problematic areas seen in Chinese and described techniques based on our experience with hyaluronic acid fillers, while considering peer-reviewed articles, followed by multiple consensus-developing sessions. Results: Chinese faces are characterized by retruded forehead, chin, and low nasal bridge, with certain features believed to bring good fortune. Therefore, profiles of the forehead, nose, lip, and chin have substantial effects on attractiveness. The demand for cosmetic procedures is high among the young generation who particularly desire nose and chin augmentation. Attractive Chinese facial shapes are characterized by a long, slender facial shape and pointed chin. Lips are narrow and thick. When injecting fillers for Chinese, it is necessary to apply special methods that produce results consistent with these characteristics. Conclusions: Understanding the concept and demand of beauty depending on race and region is important. Patients should be evaluated before aesthetic procedures. Maintaining hygiene during the procedure is crucial. Moreover, methods for preventing pain are essential. Fillers should be injected into the correct anatomical site and layer to minimize side effects and maximize effectiveness.

“…It may be caused by direct intraarterial injection, retrograde flow, or extrinsic vascular compression, and cause serious adverse effects. [2][3][4][5][6] Several authors have proposed different techniques to avoid this [6][7][8][9][10][11] ; nonetheless, even with a broad knowledge of facial anatomy, 12 it is a serious and unavoidable risk. Subcutaneous hyaluronidase has been described as an emergency treatment in an attempt to dissolve the embolism.…”

Background: The use of hyaluronidase in hyaluronic acid vascular occlusion has been evaluated; however, the models used do not accurately assimilate the facial morphologic characteristics or study the effects on adjacent tissues. The purpose of this study was to determine an effective concentration of subcutaneous hyaluronidase to dissolve a hyaluronic acid embolism and its effect on surrounding tissue. Methods: Fifteen rabbits were divided into six groups. An inguinal incision was performed on the femoral artery to create a hyaluronic acid embolism in the control and treatment groups (low-, medium-, and high-hyaluronidase groups). Hyaluronidase was injected subcutaneously. Photographic follow-up, histologic analysis, and quantification of hyaluronic acid were performed. Kruskal-Wallis test and post hoc with Bonferroni correction (p < 0.05) was used to compare the presence of hyaluronic acid in the arterial lumen between groups. Results: Despite the persistence of intravascular hyaluronic acid, macroscopic and microscopic differences were found between the embolism control group and embolism hyaluronidase high-dose group. Histologic analysis demonstrated thrombosis throughout groups. Skeletal muscle was least affected in the embolism hyaluronidase 500 IU group with less lysis and inflammatory infiltrate. Conclusions: A 500 IU hyaluronidase dose partially prevents the damage caused by the embolism, and does not affect the surrounding tissue. The use of thrombolytic therapy combined with higher doses of hyaluronidase subcutaneously in this model is proposed.
