Right Neck Dissection

Surgical Correlation

Tags

Dissection of the right side of the neck with exposure of the submandibular and carotid triangles. The internal jugular vein (blue) is reflected away from the carotid arterial tree. The hypoglossal nerve can be seen coursing toward the floor of the mouth between the posterior belly of the digastric muscle and the landmark hyoid bone. The internal branch of the superior laryngeal nerve is shown coursing through the thyrohyoid membrane in company with the superior laryngeal artery (a branch of the superior thyroid artery). Similarly, the external branch of the superior laryngeal nerve can be seen accompanying the superior thyroid artery in its descent to the upper border of the thyroidgland. (Image courtesy of AL Rhoton, Jr.)
