Facial Nerve Course Animation

The graft is microsurgically repaired to distal functioning nerve branches allowing re population of the nerve graft with sprouting axons used to innervate a functional muscle in 6 months to a year after the first stage operation. The geniculate ganglion nervus intermedius and greater superficial petrosal nerve are visible by the fifth week. Using the chorda tympani nerve as a guide is a conservative and safe way to take down the facial ridge without risk of facial nerve injury and keeps the surgeon at least 15 2 mm away from.

The course of the facial nerve is very complex.

Anatomically the course of the facial nerve can be divided into two parts. The second branchial arch gives rise to the muscles of facial expression in the seventh and eighth week. To innervate these muscles facial nerve courses across the region that eventually becomes the middle ear. An image depicting the facial nerve can be seen below.

Regarding facial expression there is one vitally important nerve that allows us to partake in this form of communication and that is the facial nerve. Superior view of the intracranial meatal labyrinthine and tympanic segments of the facial nerve. The facial nerve is the seventh cranial nerve or simply cranial nerve vii. The nerves typically travels from the pons through the facial canal in the temporal bone and exits the skull at the stylomastoid foramen.

The facial nerve is the seventh cranial nerve or simply cn viiit emerges from the pons of the brainstem controls the muscles of facial expression and functions in the conveyance of taste sensations from the anterior two thirds of the tongue. There are many branches which transmit a combination of sensory motor and parasympathetic fibres. Intracranial the course of the nerve through the cranial cavity and the cranium itself. Branches of the non parlalyzed facial nerve are exposed and used as donors to motor the cross facial nerve graft.
