What are the structures of the anterior triangle?

The anterior triangle is a region of the neck bounded by the sternocleidomastoid muscle, the mandible, and the midline of the neck. There are several important structures located within the anterior triangle, including the hyoid bone, thyroid gland, and larynx. Additionally, several major blood vessels and nerves pass through this region, including the common carotid artery and internal jugular vein, as well as the vagus nerve and hypoglossal nerve. Understanding the anatomy of the anterior triangle is essential for clinicians diagnosing and treating conditions affecting this region of the neck.
