Abstract
The hypoglossal nerve according to its embryological origin, function and nerve fibers is completly different from vagus nerve. Except their relationship at the base of the skull where the hypoglossal nerve receives some fibers from the inferior vagal ganglion, along the rest of their way to carotid triangle they are separated from each other and in surgical approach to pharyngeal wall or carotid sheath each of them are clearly distinguishable. The inferior vagal ganglion the hypoglossal nerve entered the carotid sheath and descended as a common trunk with vagus nerve down to the angle of mandible where it left the trunk as a major branch to tongue. This rare case has been reported due to its great surgical importance at the side of neck and carotid sheath.
