Thus a lesion to the facial colliculus would result in facial muscle paralysis.

Each facial colliculus, contrary to their names, do not contain the facial nerve nuclei.

The facial colliculus is an elevated area located on the dorsal pons in the floor of the 4th ventricle.

This can also include a complete absence of a formation in the pons, the facial colliculus, which is responsible for some facial movements.

Axons from the facial nerve loop around the abducens nucleus, creating a slight bulge (the facial colliculus) that is visible on the dorsal surface of the floor of the fourth ventricle.

The abducens nucleus along with the internal genu of the facial nerve make up the facial colliculus, a hump at the caudal end of the medial eminence on the dorsal aspect of the pons.
