What are the branches of maxillary division of trigeminal nerve?

The maxillary nerve is divided into 3 branches: the zygomatic, pterygopalatine (or sphenopalatine), and posterior superior alveolar nerves. Diagram of the second branch (maxillary) of the trigeminal nerve with its branches.

What are the maxillary 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.

What are the three divisions of the trigeminal nerve?

The sensory portion of the trigeminal supplies touch–pain–temperature to the face. The nerve has three divisions: the ophthalmic, maxillary, and mandibular nerves (Figure 61.1).

What happens if the maxillary nerve is damaged?

As a branch of the trigeminal nerve, the maxillary nerve is often implicated in trigeminal neuralgia, a rare condition characterized by severe pain in the face and jaw. 1 In addition, lesions of this nerve can cause intense hot and cold sensations in the teeth.

Do facial nerves repair themselves?

Facial nerve repair is infrequently required, because most of these patients regain function spontaneously. When paralysis is permanent, some advocate facial nerve decompression in selected cases.

What are the branches of maxillary nerve?

It gives rise to numerous sensory branches:

Superior alveolar nerve (anterior, posterior and middle)
Middle meningeal nerve.
Infraorbital nerve.
Zygomatic nerve.
Inferior palpebral nerve.
Superior labial nerve.
Pharyngeal nerve.
Greater and lesser palatine nerves.

Can the trigeminal nerve heal itself?

The short answer to this question is not likely. Trigeminal neuralgia may continue to worsen, rather than improve, over time. This means that you may start out with a milder case but it can continue to progress and the pain may intensify over time.

Where is the maxillary nerve located in the brain?

The maxillary nerve is the second of three branches of the trigeminal nerve. It arises between the trigeminal’s ophthalmic and mandibular divisions in a region called the trigeminal ganglion, a cluster of nerves involved in relaying sensory information to the brain as well as chewing motor function. 2 .

What kind of pain does the maxillary nerve cause?

When infected by the varicella zoster virus (also known as shingles), persistent neuropathic (nerve-associated) pain is far more common than loss of sensation. The maxillary nerve is the second of three branches of the trigeminal nerve.

Why is the maxillary nerve called the trigeminal depression?

For this reason, this depression is called the trigeminal depression, and the ganglion itself is wrapped within the dura mater in a cave-like appearance; it is called the trigeminal cave. This ganglion is the expansion of the sensory root; it contains the bodies of the sensory neurons whose fibers contribute to the making of the trigeminal nerve.

Is the maxillary nerve a palatine or nasopalatine nerve?

Other variations include a greater palatine nerve—rather than maxillary nerve—that services the upper molar and premolar teeth. 2 Finally, the nasopalatine nerve is sometimes observed innervating the incisor teeth. As noted above, the maxillary nerve is an afferent, meaning it serves a sensory function.
