Quick Facts
Origin: Supraorbital nerve.
Course: Runs from its origin near the supraorbital foramen superiorly on the forehead, deep to the musculature, eventually piercing the epicranial aponeurosis to innervate the skin of the scalp.
Branches: None.
Supply: Conveys general sensation from the forehead, frontal sinus, skin of the upper eyelid, and conjunctiva.

Origin
The lateral branch of the supraorbital nerve is a branch of the supraorbital nerve that originates just proximal or distal to the supraorbital foramen.
Course
The lateral branch of the supraorbital nerve runs through the supraorbital foramen or notch to exit the orbit in cases where it originates within the orbit. It ascends the forehead deep to the frontalis muscle, only becoming cutaneous after piercing the epicranial aponeurosis at the level of the scalp.
Branches
There are no named branches.
Supplied Structures
The lateral branch of the supraorbital nerve is a sensory nerve that conveys general sensation from the skin of the forehead and scalp.

Supraorbital Nerve
The supraorbital nerve exits the frontal bone through the supraorbital foramen and provides sensation to the superior aspects of the eye and the forehead and, extending posteriorly, provides cutaneous coverage to a large portion of the scalp.
