What is the V2 nerve?

What is the V2 nerve?

The maxillary nerve is the second division of the trigeminal nerve and is also known as the V2 division. This nerve is the middle division of the trigeminal nerve and is attached to the distal convex border of the trigeminal ganglion. The maxillary nerve exits from the cranial cavity through the foramen rotundum.

Is maxillary nerve V2?

The intermediate division, maxillary nerve (V2), primarily supplies sensory innervation to the middle third of the face. It also carries postganglionic fibers from pterygopalatine ganglion which supply the lacrimal gland and mucous glands of the nasal mucosa.

What does the maxillary nerve do?

It helps relay sensation and pain messaging from the upper teeth, jaw, the mucosa (membranes) of the nasal cavity, as well as part of the tongue and face.

What is V2 distribution?

V1/V2 distribution – Referring to the ophthalmic and maxillary branches. V2/V3 distribution – Referring to the maxillary and mandibular branches. V1-V3 distribution – Referring to all three branches.

What are the branches of v2?


  • Zygomatic nerve (zygomaticotemporal nerve, zygomaticofacial nerve), through the Inferior orbital fissure.
  • Nasopalatine nerve, through the sphenopalatine foramen.
  • Posterior superior alveolar nerve.
  • Greater and lesser palatine nerves.
  • Pharyngeal nerve.

What nerve affects nose?

The trigeminal nerve is the largest of the 12 cranial nerves. Its main function is transmitting sensory information to the skin, sinuses, and mucous membranes in the face.

Can neck problems cause trigeminal neuralgia?

Therefore, concussive trauma to the head and neck or upper back that cause injury to nerve pathways in the spinal cord and brain stem and it can be cause of trigeminal neuralgia.

Can trigeminal neuralgia Type 2 go away?

Those that undergo MVD for the trigeminal neuralgia usually notice positive results right away. The recovery time is relatively short for this procedure and the nerve’s function is not compromised.

Can maxillary sinusitis cause trigeminal neuralgia?

Mild sphenoid sinusitis is not usually considered to induce trigeminal neuralgia, especially when limited to the maxillary nerve.

What is the most painful nerve in the body?

Trigeminal Neuralgia

  • Trigeminal neuralgia (TN), also known as tic douloureux, is sometimes described as the most excruciating pain known to humanity.
  • Magnetic resonance imaging (MRI) can detect if a tumor or MS is affecting the trigeminal nerve.

What is the treatment for V2 maxillary nerve damage?

Cranial Nerve V2: Maxillary Nerve. Phenytoin, carbamazepine, baclofen, and other central-acting drugs may provide relief. Failing medical management, trigeminal rhizotomy proximal to the exit of the damaged branch may be indicated if trial injections of local anesthetics provide symptomatic relief.

What is the maxillary nerve?

The maxillary nerve is one of the branches of the trigeminal nerve, otherwise known as the fifth cranial nerve (CN V). Supplying sensory innervation to certain parts of the face, the mucosa of the nose, together with the teeth, this nerve allows you to feel that annoying fly landing underneath your eye or that annoying pain caused by your dentist.

How does the maxillary nerve leave the middle cranial fossa?

The nerve leaves the middle cranial fossa after it passes through the foramen rotundum and enters the upper part of the pterygopalatine fossa . In this fossa, the nerve extends the most of its branches. The fibers of the maxillary nerve leave the fossa by coursing forward through the pterygomaxillary fissure and then enter the infratemporal fossa.

What is the difference between maxillary and trigeminal neuralgia?

Since the maxillary nerve is a division of the trigeminal nerve, most of the clinical conditions are described together. Trigeminal neuralgia is a complex sensory disorder that affects the sensory root of the trigeminal nerve. The pain is usually in the region of both the mandibular nerve and the maxillary nerves.
