  23. 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. • ( j anat.soc.india,52(1),64-65 (2003)) www.indiandentalacademy.com
  24. 24. www.indiandentalacademy.com
  25. 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) www.indiandentalacademy.com
