•
Tributaries

23. UNUSUAL VENOUS DRIANAGE
PATTERN
• In one of the cadavers the following variation was
observed, the facial vein was found running downward &
backwards at the anterior border of masseter,where the
submental vein united with the facial vein to form a
common venous channel.the common venous channel
united with the retromandibular vein at the angle of the
mandible to form the common facial vein. Before this
common facial vein joins the internal jugular vein , a venous
channel originating from the anterior jugular vein comes &
joins the common facial vein &which then joins the internal
jugular vein.

25. • The common facial vein does not exist. The retromandibualr vein
continues into the external jugular vein, the facial vein opens into
the internal jugular r vein.
• The retromandibular vein opens into the internal jugular vein, the
facial vein continues into the anterior jugular vein, and a common
facial vein again is absent.
• The common facial vein loses its connection with the internal
jugular vein and empties instead into the external jugular
vein.(choudhary et al )
• Retromandibular vein continues into the external jugular vein, facial
vein continues into the anterior jugular vein.
• A case of facial vein uniting with the superficial temporal vein 5
mm cranial to the undivided part of retromandibular vein has been
reported by Peuker et al (2001)
