Either: Sternocleidomastoid nodes > subtrapezius nodes > supraclavicular nodes > thoracic duct (left) or lymphatic duct (right).

Or: Infraauricular nodes > internal jugular nodes > supraclavicular nodes > jugular trunk > thoracic duct (left) or right lymphatic duct.

Description

The mastoid lymph nodes are located under the auricularis posterior muscle on the surface of the mastoid bone. These nodes, one or two in number, receive afferents from the scalp over the temporoparietal region, from the auricle itself, and often the ear canal.

Drainage of lymph occurs via the sternocleidomastoid nodes of the accessory chain, or via the infraauricular nodes and the deep lateral cervical lymph nodes located close to the internal jugular vein (Földi et al., 2012).

Lymph Node

Lymph nodes (LN) are secondary lymphoid organs distributed throughout the body located alongside the lymphatic vasculature that drains peripheral tissues and organs of the body to deliver molecules, antigens, microorganisms, and cells such as lymphocytes and antigen-presenting cells (APCs) from the tissues [151].
