Filler injections have become exceedingly popular in the last decade, and injectors across the globe are using them for facial contouring and reversing the age-related changes. Thorough knowledge about the anatomy of important vessels and tissue planes is essential for injectors. During filler injections, injectors generally tend to pinch or pull the tissues with the nondominant hand for the ease of the procedure.
With the popularity of filler injections globally, more and more injectors are using them for facial shaping and reversing the aging changes of the face. Detailed knowledge of facial anatomy, especially of important vessels and tissue planes is essential for injectors. While performing filler injections, injectors tend to pinch the tissue layers with their non-dominant hand for ease of doing the procedure. Such deformational forces cause some changes in the anatomy of tissue layers held in a pinch. During a deep pinch, the important arteries in that area can get pulled up in the pinch's tissue layers, or they can stay in their position being unaffected by pinching. The ‘pinch and pull’ can also improve the tissue space for injections, by pulling away the mobile tissue layers from the fixed ones. Knowledge of the ‘pinch anatomy’ in the forehead can be used to the injector's advantage to avoid important arteries and place filler in the correct plane. By knowing the anatomical changes during the pinched state of tissue layers, filler injections in the forehead can be performed with relative safety in the correct tissue plane.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
