Supraorbital Nerve Block
Supraorbital nerve block can be useful in the management of supraorbital neuralgia.Supraorbital neuralgia is a rare type of neuralgia characterized by persistent pain over the supraorbital region and forehead along with shock-like paresthesias in the distribution of the supraorbital nerve. It is also known as a goggle headache or swimmer’s headache.
The supraorbital nerve is formed from the fibers of the frontal nerve, which is the largest branch of the ophthalmic nerve. The frontal nerve enters the orbit via the superior orbital fissure as it passes anteriorly beneath the periosteum of the roof of the orbit. The frontal nerve gives off a larger branch, the supraorbital nerve and a smaller medial branch, the supratrochlear nerve. Both exit the orbit anteriorly. The supraorbital nerve sends fibers to the vertex of the scalp and provides sensory innervation to the forehead, upper eyelid, and anterior scalp. The supraorbital nerve is a pure sensory nerve.
