QS Study

The face is developed by the fusion of a number of important processes around the stomodeum, namely front nasal process, maxillary process, and mandibular process. The external human face develops between the 4th and 6th week of embryonic development.

Lymphatic drainage of the face –

Lymph from the forehead & the anterior part of the face drains into the submandibular lymph nodes.  The lymph nodes of the head and neck can be divided into two groups; a superficial ring of lymph nodes, and a vertical group of deep lymph nodes

A few buccal lymph nodes may be present along the course of these lymph vessels.

The lateral part of the face, including the lateral parts of the eyelids, is drained by lymph vessels that end in the parotid lymph nodes.

The central part of the lower lip and the skin of the chin are drained into the submental lymph node.

The deep cervical lymph nodes drain into the jugular lymphatic trunk, which joins the internal jugular vein or brachiocephalic vein on the right side and thoracic duct on the left side. They are organized into a vertical chain, located within close proximity to the internal jugular vein within the carotid sheath.

Lymphatic nodes are categorized into several groups:

  • Parotid lymph nodes: Receive lymph from the side of the face and scalp. They receive lymph from the lateral half of the eyelids, conjunctiva, cheek and parotid region.
  • Submandibular lymph nodes: Get lymph from the upper lip and part of the lower lip as well as most of the oral cavity. They are situated along with submandibular salivary gland between the layers of investing layer of deep cervical fascia.
  • Submental lymph nodes: Get lymph from the chin and center of the lower lip. They receive lymph from the midline of the lower lip, chin, tip of the tongue and related areas.

Dangerous area of the face –

Upper lip & lower part of the nose is called dangerous area of the face because from this area infection can be spread in a retrograde direction and this result in thrombosis of the cavernous sinus as a result of the connection of facial vein with the cavernous sinus.
