Retromandibular vein
Retromandibular vein
The Retromandibular vein (pronunciation: retro-man-dib-u-lar vein) is a significant vein located within the human face. It is formed by the union of the superficial temporal vein and the maxillary vein.
Etymology
The term "retromandibular" is derived from the Latin words "retro" meaning behind, and "mandibula" meaning jaw. Thus, the term refers to the vein's location behind the mandible or jawbone.
Anatomy
The retromandibular vein is formed within the parotid gland, a major salivary gland located in front of the ear. It descends within the substance of the gland, and exits its lower part to divide into an anterior and a posterior division. The anterior division combines with the facial vein to form the common facial vein, while the posterior division combines with the posterior auricular vein to form the external jugular vein.
Clinical Significance
The retromandibular vein is an important landmark in surgeries involving the parotid gland or the temporomandibular joint. Its location and relation to other structures in the face make it susceptible to injury during surgical procedures.
