The infraorbital nerve is a branch of the maxillary nerve (itself a branch of the trigeminal nerve (CN V)). [1] It arises in the pterygopalatine fossa . It passes through the inferior orbital fissure to enter the orbit. [ 2 ]
Infraorbital nerve enlargement (IONE) is considered to be a particularly suspicious sign of IgG4-ROD, but seems to occur only when inflammation is in direct contact with the infraorbital canal. [10] IONE is defined as the infraorbital nerve diameter being greater than the optic nerve diameter in the coronal plane.
Neuroinflammation is widely regarded as chronic, as opposed to acute, inflammation of the central nervous system. [5] Acute inflammation usually follows injury to the central nervous system immediately, and is characterized by inflammatory molecules, endothelial cell activation, platelet deposition, and tissue edema.

The anterior superior alveolar nerve (or anterior superior dental nerve) is a branch of the infraorbital nerve (itself a branch of the maxillary nerve (CN V 2)). [1] It passes through the canalis sinuosus to reach and innervate upper front teeth. Through its nasal branch, it also innervates parts of the nasal cavity.
Maxillary sinusitis is inflammation of the maxillary sinuses. The symptoms of sinusitis are headache, usually near the involved sinus, and foul-smelling nasal or pharyngeal discharge, possibly with some systemic signs of infection such as fever and weakness.
A new review reports that nine people taking semaglutide and tirzepatide — the active ingredient in GLP-1 medications — experienced vision issues, including three potentially blinding eye ...
Orbital cellulitis is inflammation of eye tissues behind the orbital septum. It is most commonly caused by an acute spread of infection into the eye socket from either the adjacent sinuses or through the blood. It may also occur after trauma. When it affects the rear of the eye, it is known as retro-orbital cellulitis.
This is a type of nerve damage accompanied by burning that lasts for years after you recover from shingles. A few risk factors for developing PHN are: Being older.
