In vivo studies, based on magnetic resonance imaging (MRI), enabled the creation of a unique image database capturing facial expressions associated with joy, anger, surprise, and sadness. A detailed anatomical description was provided, defining for the first time the contraction patterns of facial muscles and their role in shaping facial expressions, emphasizing the influence of agonists and antagonists on facial compartment stabilization. The study challenges the traditional view that facial expression is the key indicator of muscle function, highlighting changes in muscle thickness as a more reliable marker of activity. The developed atlas of facial muscle function can be applied in plastic and reconstructive surgery, diagnostics, rehabilitation, and therapy monitoring, underscoring the significance of imaging studies in clinical practice.}, title={Analysis of facial muscle contraction patterns in the middle and upper facial regions using magnetic resonance imaging : functional anatomy and clinical implications}, type={Praca doktorska}, keywords={facial muscles, facial anatomy, magnetic resonance imaging, contraction patterns, facial expression}, }
