Filler injections have become very popular in recent years, and injectors globally use them for facial shaping and reversing age-related changes. Detailed knowledge about important vessels' and tissue planes' anatomy is essential for injectors. While giving the filler injections, injectors tend to gently pinch or pull the tissue fold with the nondominant hand during the procedure. The deformational forces cause some changes in the anatomy of tissue layers held in a pinch. During the pinch and "pinch and pull" maneuver, the crucial vessels in the area can get pulled up in the tissue layers in a pinch or stay in their position unaffected depending on the force applied. The "pinch and pull" maneuver also increases the tissue space for injections by moving the mobile tissue layers away from the fixed ones. The injector can use knowledge of the "'pinch anatomy" in the forehead to avoid important arteries and place filler in the correct plane. With the understanding of the anatomical changes occurring during the pinched state of tissue layers, filler injection can be performed in the right and safer tissue plane in the forehead. This study reflects level of evidence V.
近年来，填充物注射变得非常流行，全球的注射者都将其用于面部塑形和逆转与年龄相关的变化。对于注射者来说，详细了解重要血管和组织平面的解剖结构至关重要。在进行填充物注射时，注射者在操作过程中往往会用非优势手轻轻捏或拉组织褶皱。变形力会导致夹捏时所夹持的组织层的解剖结构发生一些变化。在夹捏和“夹捏并牵拉”操作过程中，该区域的关键血管可能会被夹捏在组织层中向上牵拉，或者根据施加的力保持在其位置不变。“夹捏并牵拉”操作还通过将移动的组织层从固定组织层移开，增加了注射的组织空间。注射者可以利用额部“夹捏解剖”的知识来避免重要的动脉，并将填充物放置在正确的平面上。通过了解组织层夹捏状态下发生的解剖变化，可以在额部正确且更安全的组织平面进行填充物注射。本研究反映了证据水平 V。
