infraorbital nerve


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

in·fra·or·bit·al nerve

[TA]
the continuation of the maxillary nerve [CN V2] after it has traversed the pterygopalatine fossa and enters the orbit, via the infraorbital fissure, it is then transmitted by the infraorbital canal to reach the face; it supplies the mucosa of the maxillary sinus, the upper incisors, canine and premolars, the upper gums, the inferior eyelid and conjunctiva, part of the nose, and the superior lip.
Synonym(s): nervus infraorbitalis [TA]

infraorbital nerve

The terminal branch of the maxillary nerve (CN V2). It is a sensory nerve that leaves the floor of the orbit through the infraorbital foramen and innervates the upper incisors and canine teeth, the mucosa of the maxillary sinus, and the skin of the lower eyelid, cheek, side of the nose, and upper lip.

The infraorbital nerve block is widely used to accomplish regional anaesthesia during surgeries involving the midface region and paranasal sinuses [2, 3].
The CT identified an unusual anatomic variation: The right infraorbital nerve canal passed through the lumen of the maxillary sinus within the lamella of an infraorbital ethmoid (Haller's) cell (figure).
The maxillary nerve leaves the pterygopalatine fossa through the infraorbital fissure and becomes the infraorbital nerve in the orbital cavity (Figure 7).
A woman aged 34 complained about brief stabbing pain in the innervated right areas of the infraorbital nerve that lasted for four years.

This nerve is a branch of infraorbital nerve, maxillary nerve, in the second division of the trigeminal nerve.
Nerves were separated from the surrounding connective tissues carefully, and then the infraorbital nerve (ION), which is the secondary branch of the trigeminal nerve, was exposed clearly.
Care was taken to avoid injury to the infraorbital nerve. The conjunctiva and retractor band were incised horizontally below the tarsus, and a porcine collagen matrix graft (Enduragen TM, Stryker, Kalamazoo, MI) was cut into an ovoid configuration and sewn into the posterior lamella defect with interrupted 6-0 chromic sutures.
Additionally, infraorbital nerve block was also performed with 2% Lignocaine hydrochloride (Xylocaine (b)).
Under local anesthesia (bilateral infraorbital nerve blocks), excess tissue was marked using methylene blue dye and the redundant labial mucosal mass was excised by two elliptical excisions, one on each half of the lip, and combined with a central Z-plasty to release the constricting band (Figure 2).
(2-4) The nasal tip is also supplied by branches of the infraorbital nerve.
In Japan, infraorbital nerve swelling was observed more frequently in AIP patients than in those without history of AIP.9 A study reported a case from Bristol, United Kingdom, of an orbital mass in a 5-year-old child which was due to IgG4 related orbital inflammation.10 This was the youngest reported case of IgG4 related disease.
