injection to masseter muscle with real-time ultrasound

Sadiya Naseem on Instagram: "This ultrasound image shows the right masseter muscle—and just as importantly, the facial artery. Key anatomical landmark: The anterior border (end) of the masseter muscle is a reliable landmark for identifying the facial artery, as it curves around the mandible and ascends toward the face. Why this matters: • Helps avoid vascular injury • Improves injection precision • Enhances patient safety • Reinforces anatomy beyond surface landmarks Seeing anatomy in real time

It consists of a superficial and a deep part. It is one of the masticatory muscles, a group of muscles which also includes the temporal muscle, lateral pterygoid muscle and medial pterygoid muscle. Its specific functions are elevation and protrusion of the mandible, as well as providing support to the articu
