The neck is dissected surgically into 6 sections following lymphatic drainage and anatomical landmarks, with levels 1, 2 and 5 being subdivided into a and b.
Easy way to remember is the submental and submandibular regions are 1a and 1b respectively, the sternocleidomastoid is 2,3 and 4, the posterior triangle is 5a and 5b, the thyroid Adam’s Apple region is level 6.
Going to do a more in-depth video explaining the levels and it’s sonographic appearance.
