Eyelid

eyelidspalpebralpalpebra
This nerve innervates (sensory) the lower eyelid, upper lip, and part of the nasal vestibule and exits the infraorbital foramen of the maxilla.
In humans, the sensory nerve supply to the upper eyelids is from the infratrochlear, supratrochlear, supraorbital and the lacrimal nerves from the ophthalmic branch (V1) of the trigeminal nerve (CN V). The skin of the lower eyelid is supplied by branches of the infratrochlear at the medial angle, the rest is supplied by branches of the infraorbital nerve of the maxillary branch (V2) of the trigeminal nerve.

Infraorbital canal

orbital canal
After the maxillary nerve enters the infraorbital canal, the nerve is frequently called the infraorbital nerve.
The infraorbital nerve and infraorbital artery travel through the canal.

Lip

upper liplower liplips
This nerve innervates (sensory) the lower eyelid, upper lip, and part of the nasal vestibule and exits the infraorbital foramen of the maxilla.
The infraorbital nerve is a branch of the maxillary branch. It supplies not only the upper lip, but much of the skin of the face between the upper lip and the lower eyelid, except for the bridge of the nose.

Infraorbital foramen

Foramen infraorbitaleinfraorbital foraminaforamen on the maxilla
This nerve innervates (sensory) the lower eyelid, upper lip, and part of the nasal vestibule and exits the infraorbital foramen of the maxilla.
It transmits the infraorbital artery and vein, and the infraorbital nerve, a branch of the maxillary nerve.

Infraorbital artery

Infraorbital artery
It runs along the infraorbital groove and canal with the infraorbital nerve, and emerges on the face through the infraorbital foramen, beneath the infraorbital head of the levator labii superioris muscle.

Orbital blowout fracture

They are characterized by double vision, sunken ocular globes, and loss of sensation of the cheek and upper gums due to infraorbital nerve injury.

Middle superior alveolar nerve

middle superior alveolar branch
The middle superior alveolar nerve is a nerve that drops from the infraorbital portion of the maxillary nerve to supply the sinus mucosa, the roots of the maxillary premolars, and the mesiobuccal root of the first maxillary molar.

Zygoma reduction plasty

The infraorbital nerve supplies skin and mucous membranes to the middle portion of the face and also supplies sensation to the skin of the cheek, upper lip, nose and upper teeth.

Euchambersia

Euchambersia mirabilis
The forward-directed canal also splits into the three main branches of the infraorbital nerve, all of which connect to the socket of the canine; the junction occurs about 3 - 6 mm along the canal, another point of variation between the two skulls.

Infraorbital vein

vein
Accompanied by the infraorbital artery and the infraorbital nerve, it passes posteriorly through the infraorbital foramen, infraorbital canal, and infraorbital groove.

Orbit (anatomy)

The infraorbital foramen contains the second division of the trigeminal nerve, the infraorbital nerve or V2, and sits on the anterior wall of the maxillary sinus.

IgG4-related ophthalmic disease

Frequently involved structures include the lacrimal glands, extraocular muscles, infraorbital nerve, supraorbital nerve and eyelids.
