Orbicularis Oculi Muscle

In this course, we thoroughly examine the orbicularis oculi muscle, detailing its varying depths, adherence to surrounding areas, and extensions across the face. We discuss how muscle contractions lead to wrinkle formation and their impact on lymphatic drainage and the consequential puffy eyelids. The course also covers connections of the orbicularis oculi muscle to other facial muscles and the function and position of the orbicularis retaining ligament. A clip of an anatomic dissection is included to visually showcase these structures and their relationships, providing a comprehensive understanding of how the orbicularis oculi muscle affects facial aesthetics.
