The study "Spaces of the Face for Filler Procedures: Identification of subSMAS Spaces Based on Anatomical Study" explores the anatomy of facial spaces crucial for safe and effective filler injections. By delineating the subSMAS (sub-superficial musculoaponeurotic system) spaces, this research highlights how these virtual compartments, bordered by fat, muscles, fascia, and ligaments, facilitate independent muscle movement and reduce the risk of damaging critical structures. The thicker and more robust skin of East Asians necessitates deeper filler injections, emphasizing the significance of accurately identifying these spaces. A cadaver study with dyed gelatin validated the existence and characteristics of these subSMAS spaces, confirming their safety for filler procedures. Key spaces, such as the subgalea-frontalis, interfascial and temporalis, and prezygomatic spaces, were examined, illustrating safe zones for injections. The findings underscore the importance of anatomical knowledge for enhancing facial aesthetics while minimizing complications. This study serves as a guide for clinicians to perform precise and safe filler injections, providing a foundation for further research on the dynamic interactions of these spaces and long-term outcomes.
《用于填充手术的面部间隙：基于解剖学研究识别SMAS下间隙》这项研究探讨了对面部间隙进行安全有效的填充注射至关重要的解剖结构。通过描绘SMAS（表浅肌肉腱膜系统）下间隙，本研究突出了这些由脂肪、肌肉、筋膜和韧带界定的虚拟腔室如何促进肌肉独立运动并降低损伤关键结构的风险。东亚人较厚且更坚韧的皮肤需要更深的填充注射，这凸显了准确识别这些间隙的重要性。一项使用染色明胶的尸体研究验证了这些SMAS下间隙的存在及其特征，证实了它们在填充手术中的安全性。研究了关键间隙，如帽状腱膜 - 额肌间隙、筋膜间间隙和颞间隙以及颧前间隙，展示了注射的安全区域。研究结果强调了解剖学知识对于提升面部美学效果同时将并发症降至最低的重要性。本研究为临床医生进行精确且安全的填充注射提供了指导，为进一步研究这些间隙的动态相互作用及长期效果奠定了基础。
