Preferred Label : Submandibular Lymph Node Group (Sublevel IB);
NCIt related terms : Lymph node level IB (qualifier value);
NCIt definition : Lymph nodes within the boundaries of the anterior and posterior bellies of the digastric
muscle, the stylohyoid muscle, and the body of the mandible. These include the preglandular
and the postglandular nodes and the prevascular and postvascular nodes. The submandibular
gland is included in the specimen when the lymph nodes within the triangle are removed.
These nodes are at greatest risk for harboring metastases from cancers arising from
the oral cavity, anterior nasal cavity, skin, and soft tissue structures of the midface,
as well as from the submandibular gland. (AJCC 8th ed.);
