Because of the distribution along the spinal nerve, the lymph nodes of the posterior triangle get enlarged in viral infections. Melanoma or squamous carcinoma can metastasize in the submandibular triangle and posterior triangle.

The posterior triangle is crossed, about 2. 5 cm above the clavicle, by the inferior belly of the omohyoid muscle, which divides the space into two triangles: an upper or occipital triangle a lower or subclavian triangle (or supraclavicular triangle) When a posterior cervical lymph node is swollen due to cancer, the cancer will be treated.
