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.
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.

Forming the exterior end of the infraorbital canal, the infraorbital foramen communicates with the infraorbital groove, the canal's opening on the interior side.. The ramifications of the three principal branches of the trigeminal nerve—at the supraorbital, infraorbital, and mental foramen—are distributed on a vertical line (in anterior view) passing through the middle of the pupil.
Neuritis (/ nj ʊəˈr aɪ t ɪ s /), from the Greek νεῦρον), [1] is inflammation of a nerve [2] or the general inflammation of the peripheral nervous system.Inflammation, and frequently concomitant demyelination, [3] [4] [5] cause impaired transmission of neural signals and leads to aberrant nerve function.
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.
Idiopathic orbital inflammatory (IOI) disease refers to a marginated mass-like enhancing soft tissue involving any area of the orbit.It is the most common painful orbital mass in the adult population, and is associated with proptosis, cranial nerve palsy (Tolosa–Hunt syndrome), uveitis, and retinal detachment.
Magnesium deficiency causes neurogenic inflammation in a rat model. Researchers have theorized that since substance P which appears at day five of induced magnesium deficiency, is known to stimulate in turn the production of other inflammatory cytokines including IL-1, Interleukin 6 (IL-6), and TNF-alpha (TNFα), which begin a sharp rise at day 12, substance P is a key in the path from ...
Trigeminal nerve. The infraorbital nerve is a branch of the maxillary branch. It supplies not only the upper lip but also much of the skin of the face between the upper lip and the lower eyelid, except for the bridge of the nose. The mental nerve is a branch of the mandibular branch (via the inferior alveolar nerve).
