The trigeminal nerve the fifth cranial nerve , or simply CN V is a nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the largest of the cranial nerves. The ophthalmic and maxillary nerves are purely sensory, whereas the mandibular nerve supplies motor as well as sensory or "cutaneous" functions. The motor division of the trigeminal nerve derives from the basal plate of the embryonic pons , and the sensory division originates in the cranial neural crest. Sensory information from the face and body is processed by parallel pathways in the central nervous system. The three major branches of the trigeminal nerve—the ophthalmic nerve V 1 , the maxillary nerve V 2 and the mandibular nerve V 3 —converge on the trigeminal ganglion also called the semilunar ganglion or gasserian ganglion , located within Meckel's cave and containing the cell bodies of incoming sensory-nerve fibers.
However, careful attention is needed to avoid injection into foramina whose consequences could lead Facial nerves jaw permanent Facial nerves jaw damage. FDA alerts. Who is Affected? The pain associated with trigeminal neuralgia represents an irritation of the nerve. All sensory and motor pathways converge and diverge to the contralateral hemisphere. Attacks of intense, electric shock-like facial pain can occur without warning or be triggered by touching specific areas of the face. Education is the Key. Cranial Nerve 5, the Trigeminal Nerve which includes the following three 3 branches:. Related News and Articles.

Symptoms of Facial nerves jaw Neuralgia Trigeminal neuralgia is an irritation of the nerve that travels to your face, cheek ajw jaw, therefore your symptoms will likely be felt there. Glossopharyngeal nerve. Facial motor nucleus Solitary nucleus Superior salivary nucleus. This disc allows for smooth articulation between the two bones. Cones are present in smaller numbers. When it is working correctly, it slides smoothly and comfortably, allowing you to move your mouth and use the jaw for chewing, talking, and yawning. Although the anterior two thirds of the tongue are derived from the first pharyngeal archwhich gives rise to cranial nerve V, not all innervation of the tongue is supplied by CN V. Wikimedia Commons has media related to Nervus facialis. The facial nerve also carries axons of type GVE, general visceral efferentwhich innervate the sublingual, Facial nerves jaw, Vintage meat advertising lacrimal glands, also mucosa of nasal cavity. The parts of the trigeminal nucleus receive different types of sensory information; the spinal trigeminal nucleus receives pain-temperature fibers, the principal sensory nucleus receives touch-position fibers and the mesencephalic nucleus receives proprioceptor and mechanoreceptor fibers Varigated hydrangea lace cap the jaws and teeth.

Regional anesthesia is commonly used for postoperative pain management to decrease postoperative pain and opioid consumption following head and neck surgery.
Myriad techniques can be used for both acute and chronic pain management either diagnostic or therapeutic procedures. Because of the vicinity of cranial and cervical nerves to many vital structures in a compact area, the efficacy and safety of cephalic blocks are based on precise and detailed knowledge of the anatomical relationships of the selected nerve, its deep and superficial courses, and the final sensory territories.
Sensory innervation of the face and neck is supplied by the trigeminal nerve fifth cranial or V and the C2—C4 cervical nerve roots that constitute the superficial cervical plexus Figure 1A.
This section outlines clinically applicable regional blocks of the face that for perioperative and chronic pain management. For each block, practical anatomy, indications, technique, and type of complications are specifically described.
The fifth cranial nerve carries both sensory and motor components. It innervates the lower eyelid, the upper lip, the lateral portion of the nose and nasal septum, cheek, roof of the mouth, bone, teeth and sinus of the maxilla, and the soft and hard palates Figure 1B. After exiting the cranium through the foramen ovale, it delivers sensory branches that supply the front of the ear, the temporal area, the anterior two-thirds of the tongue and the skin, mucosa, and teeth and bone of the mandible Figure 1B.
For superficial trigeminal nerve blocks, the local anesthetic solution should be injected in close proximity to the three individual terminal superficial branches of the trigeminal nerve divisions: frontal nerve of the ophthalmic nerve, V1 division ; infraorbital nerve of the maxillary nerve, V2 division ; and mental nerve sensory terminal branch of the mandibular nerve, V3 division.
Each nerve is anatomically close to its respective foramen, usually located on a line drawn sagittally through the pupil Figure 2. Block of the Frontal Nerve Supraorbital and Supratrochlear Branches Anatomy The frontal nerve enters the orbit at the superior orbital fissure and divides into the supraorbital and supratrochlear branches.
The supraorbital nerve exits with its vessels through the supraorbital foramen and continues superiorly between the elevator palpebrae superioris and the periosteum. These two branches supply the sensory innervation to the frontal scalp and forehead, the medial part of the upper eyelid, and the root of the nose Figures 3A and 3B.
Frequently, surgery on one side of the forehead requires a supplemental block of the contralateral supratrochlear nerve because of overlapping distributions of the nerves. Block of branches of the ophthalmic nerve has been described for the management of acute migraine headache attacks localized to the ocular and retro-ocular region and in the treatment of pain related to acute herpes zoster. Classical Landmark Technique The supraorbital foramen can easily be palpated by following the orbit rim 2 cm from the midline in adults intersection of the medial one-third and the lateral two-thirds.
The needle gauge intradermal needle in adults, 30 gauge in children is introduced 0. When the needle tip is near the supraorbital notch, after test aspiration, and with caution not to penetrate the foramen, local anesthetic solution 0. The supratrochlear nerve can be blocked immediately following supraorbital nerve block, without removing the needle, by directing the needle about 1 cm toward the midline and injecting an additional 0.
After the injection, firm pressure is applied for better anesthetic spread and prevention of ecchymosis. Complications are rarely reported during the performance of this block, and may include hematoma, intravascular injection, and eye globe damage. Indications Infraorbital nerve block is commonly used in neonates, infants, and older children undergoing cleft lip repair to provide early postoperative analgesia without the potential risk of respiratory depression that may occur when opioid analgesics are used.
As the nerve exits the infraorbital foramen, it supplies the skin of the lower eyelid, nose, cheek, and upper lip. Classical Landmark Techniques For the classical landmark techniques, two approaches can be used to perform this block: the intraoral and extraoral approaches.
Regardless of the chosen technique, it is necessary to prevent the penetration of the foramen to prevent damage to the eyeball. This can be done by keeping a finger on the foramen throughout the procedure. The incisor and the first premolar are then palpated. A to gauge needle is inserted into the buccal mucosa in the subsulcal groove at the level of the canine or the first premolar and directed upward and outward into the canine fossa.
A finger is kept over the infraorbital foramen to assess the proper location of the needle tip and to avoid damage of the eyeball by accidental cephalad advancement of the needle into the orbit.
Then, 1—3 mL of local anesthetic is injected after negative aspiration. A to gauge needle is advanced perpendicularly with a cephalic and medial direction toward the foramen until bony resistance is appreciated.
Because the axis of the infraorbital foramen is oriented caudally and medially, a lateral-to-medial approach reduces the risk of penetration of the foramen. Complications Hematoma formation, persistent paresthesia of the upper lip, prolonged numbness of the upper lip, and intravascular placement are possible. A serious but rare risk is penetration of the foramen, which may result in nerve damage by compression in the narrow infraorbital canal, or needle penetration of the flimsy orbital floor and damage to the orbital contents.
The intraoral approach is not advised in neonates and small infants because of the proximity of the orbit. Block of the Mental Nerve Anatomy The mental nerve is the terminal branch of the alveolar nerve the largest branch of the mandibular nerve, V3. It emerges at the mental foramen and divides into three branches: a descending branch to the skin of the chin and two ascending branches to the skin, labial mucosae of the lower lip, as well as the anterior teeth Figures 5A and 5B.
Indications Procedures involving hemangiomata, laceration repair, and other surgery involving the lower lip, skin of the chin, and the incisive and canine teeth. Classical Landmark Technique For the classical landmark technique, the mental foramen is located in line with the pupil on the mental process of the mandible, in regard to the inferior premolar tooth.
Puncture with a to gauge needle is performed 1 cm lateral to the foramen palpated. The needle is directed with a lateral-to-medial direction to avoid foramen penetration. Similar to the infraorbital nerve block, an intraoral route can be utilized: The lower lip is retracted, and the needle is introduced through the mucosa in front of the first inferior premolar tooth. The needle is directed downward and outward toward the mental foramen palpated with the finger. Complications Hematoma formation and persistent paresthesia have been reported.
Less commonly, penetration of the foramen occurs, which may result in permanent nerve damage or vascular injection. Ultrasound Guidance Technique for Superficial Trigeminal Nerve Blocks The ultrasound-guided approach to locate the landmark foramina for superficial trigeminal nerve block is feasible. Using a high-frequency linear transducer, bone appears as a hyperechoic linear edge white line with an underlying anechoic dark shadow.
In addition, ultrasound can visualize satellite vessels close to each nerve using the color Doppler function. The real-time view of the injection spread can help avoid intravascular injection, nerve injury by the needle, or injection into the foramen. To localize the supraorbital notch foramen , the probe is located transversely above the orbital rim Figure 6A.
The infraorbital foramen can be visualized by positioning the ultrasound probe horizontally or vertically in the sagittal plane. Fine translational movements from medial to lateral along the lower orbital margin are performed to highlight the disruption of the bone table Figure 6B.
Finally, the mental foramen is localized using a transverse or sagittal plane with dynamic scanning between the upper and lower borders of the mandible Figure 6C. However, careful attention is needed to avoid injection into foramina whose consequences could lead to permanent neurological damage. This complication can be decreased after superficial nerves blocks techniques by using a or gauge needle and applying a manual pressure immediately after injection.
Anatomy The maxillary nerve exits the skull through the foramen rotundum before dividing into terminal branches Table 1 and Figure 7. Except for the middle meningeal nerve the intracranial branch that innervates the dura mater , all branches zygomatic branches, superior alveolar nerve, pterygopalatine and parasympathetic branches, palatine and pharyngeal branches arise in the pterygopalatine fossa. TABLE 1. Branches of the maxillary division. Middle meningeal nerve 2. Posterior superior alveolar nerve 5.
Indications This block is mainly offered as an adjunct to general anesthesia for major cancer surgery of the maxilla, the ethmoidal sinus, and the pterigomaxillary or infratemporal fossa. In children, bilateral maxillary nerve blocks improve perioperative analgesia and favor the early resumption of feeding following repair of congenital cleft palate. Many other procedures may benefit from a maxillary nerve block, such as maxillary trauma Lefort I , maxillary osteotomy, or the diagnostic and therapeutic management of trigeminal neuralgias.
Classical Landmark Technique Many approaches to the classical landmark technique Figure 8 have been described. The patient is placed supine with the head in a neutral position.
The needle entry point is found at the angle formed by the superior edge of the zygomatic arch below and the posterior orbital rim forward. The needle 22 to 25 gauge is inserted perpendicular to the skin and advanced to reach the greater wing of the sphenoid at a depth of approximately 10—15 mm Figure 8A.
The needle is then reoriented in a caudal and posterior direction Figure 8B and advanced a further 35—45 mm to reach the pterygopalatine fossa. After a negative aspiration test for blood, 0. Nerve stimulation may help locate the pterygopalatine fossa: Nerve stimulation is associated with paresthesia coinciding with the stimulating frequency of the nerve stimulator. The disappearance of the muscle contraction heralds the passage through the temporal muscle and entrance into the pterygomaxillary fossa.
Ultrasound Guidance Technique. The probe location allows visualization of the pterygopalatine fossa, limited anteriorly by the maxilla and posteriorly by the greater wing of the sphenoid.
The needle is advanced using an out-of-plane approach. Real-time ultrasound guidance allows direct localization of the internal maxillary artery, identification of the needle tip, and spread of local anesthetic solution within the pterygopalatine fossa. Complications Block failure can occur due to inadequate bony landmarks or inadequate needle tip position external to the pterygomaxillary fossa. Complications include cephalgia, facial paralysis, trismus, and hematoma.
Anatomy The mandibular nerve, the largest branch of the trigeminal nerve, exits from the cranium through the foramen ovale of the greater wing of the sphenoid. It divides into an anterior branch, which supplies motor innervation to temporalis, masseter, pterygoids, mylohyoid, tensor tympani, and palati muscles, as well as a sensory branch, the buccal nerve. The large posterior trunk divides into auriculotemporal, lingual, and inferior alveolar nerves which reach the mental foramen, becoming the mental nerve Table 2 and Figure TABLE 2.
Branches of the mandibular division. Recurrent meningeal nerve 2. Indications Surgery on the lower lip, the mandible skin or bone including the lower teeth , and the anterior two-thirds of the tongue can be accomplished with this technique. This block could be useful in patients with cancer or trauma. Nonmalignant chronic pain conditions such as trigeminal, vascular, or postherpetic neuralgia are also good indications for the mandibular block.
Classical Landmark Technique In the classical landmark technique, the puncture area is bound by the zygomatic arch at the top and the mandibular notch just anterior and below the tragus of the ear.
The needle entry point is located between the coronoid and condylar processes of the ramus of the mandible. After perpendicular skin penetration and advancement of 2—4 cm toward the lateral pterygoid plate, the to gauge needle is advanced posteriorly and inferiorly, guided by mandible elevation twitch. The minimal intensity of stimulation around 0.
This transcutaneous procedure with neurostimulation is associated with a high success rate. Complications The risk of puncture of the internal maxillary or middle meningeal arteries Figure 10 can be high when the needle inserted too high in the space between the coronoid and condylar processes. After an injection of a large volume of local anesthetic solution, transient facial nerve block has been reported, which resolved spontaneously without sequelae.
Anatomy The innervation of the nose and nasal cavity is complex and involves both the ophthalmic V1 and maxillary V2 branches of the trigeminal nerve Figures 12A and 12B. The ethmoidal branches supply the superior and anterior half of the nasal cavity and the sphenoidal, ethmoidal, and frontal sinuses. Internal and external nasal branches of the anterior ethmoidal nerve supply the anterior part of the septum, the lateral wall of the nasal cavity, the nasal bone, and skin to the tip of the nose.
Indications Bilateral nerve blocks are often required.
Near origin Intermediate nerve Geniculate. The latter pathways are analogous to the spinomesencephalic and spinoreticular tracts of the spinal cord, which send pain-temperature information from the rest of the body to the same areas. These may include: Trigeminal neuralgia TMJ Hemifacial spasm Cervicogenic headache Migraine headaches Sinus infection All of these problems may cause you to feel pain around your eye, jaw, cheek or ear. It has been found in all vertebrates except lampreys and hagfishes. The lingual branch of the mandibular division V3 of CN V supplies non-taste sensation pressure, heat, texture from the anterior part of the tongue via general visceral afferent fibers.
Facial nerves jaw. Clinical Anatomy Dummies
Your visual cortex is located in the back part of your brain. The oculomotor nerve has two different motor functions: muscle function and pupil response. This nerve originates in the front part of your midbrain, which is a part of your brainstem. It moves forward from that area until it reaches the area of your eye sockets. The trochlear nerve controls your superior oblique muscle.
It emerges from the back part of your midbrain. Like your oculomotor nerve, it moves forward until it reaches your eye sockets, where it stimulates the superior oblique muscle. The trigeminal nerve is the largest of your cranial nerves and has both sensory and motor functions.
The trigeminal nerve originates from a group of nuclei — which is a collection of nerve cells — in the midbrain and medulla regions of your brainstem. Eventually, these nuclei form a separate sensory root and motor root. The sensory root of your trigeminal nerve branches into the ophthalmic, maxillary, and mandibular divisions.
The motor root of your trigeminal nerve passes below the sensory root and is only distributed into the mandibular division. This muscle is involved in outward eye movement. For example, you would use it to look to the side. This nerve, also called the abducent nerve, starts in the pons region of your brainstem. It eventually enters your eye socket, where it controls the lateral rectus muscle. The facial nerve provides both sensory and motor functions, including:.
Your facial nerve has a very complex path. It originates in the pons area of your brainstem, where it has both a motor and sensory root. Eventually, the two nerves fuse together to form the facial nerve. Both within and outside of your skull, the facial nerve branches further into smaller nerve fibers that stimulate muscles and glands or provide sensory information.
Your vestibulocochlear nerve has sensory functions involving hearing and balance. It consists of two parts, the cochlear portion and vestibular portion:.
The cochlear and vestibular portions of your vestibulocochlear nerve originate in separate areas of the brain. The cochlear portion starts in an area of your brain called the inferior cerebellar peduncle. The vestibular portion begins in your pons and medulla. Both portions combine to form the vestibulocochlear nerve. The glossopharyngeal nerve has both motor and sensory functions, including:.
The glossopharyngeal nerve originates in a part of your brainstem called the medulla oblongata. It eventually extends into your neck and throat region. The vagus nerve is a very diverse nerve. It has both sensory and motor functions, including:.
Out of all of the cranial nerves, the vagus nerve has the longest pathway. It extends from your head all the way into your abdomen. It originates in the part of your brainstem called the medulla. Your accessory nerve is a motor nerve that controls the muscles in your neck.
These muscles allow you to rotate, flex, and extend your neck and shoulders. The spinal portion originates in the upper part of your spinal cord. The cranial part starts in your medulla oblongata. These parts meet briefly before the spinal part of the nerve moves to supply the muscles of your neck while the cranial part follows the vagus nerve.
It starts in the medulla oblongata and moves down into the jaw, where it reaches the tongue. Without it, you couldn't breathe or walk. We'll go over the different parts of the brain and explain…. Sixth nerve palsy is a disorder that causes your eye to cross inward towards your nose. It's caused when the sixth cranial nerve is damaged. Bell's palsy causes a temporary weakness or paralysis of the facial muscles. Learn about its symptoms, diagnosis, and treatment.
Have trouble blinking or closing your eyes to sleep? You might have lagophthalmos. Learn what causes this condition and how to treat it. Isolated nerve dysfunction IND is a type of neuropathy nerve damage that occurs in a single nerve. Technically it is a mononeuropathy because it…. You can do a lot of prep work to make the perfect sleep environment. But if that doesn't work, here are 6 other hacks to try. Identifying your triggers can take some time and self-reflection.
The exact causes of this condition are unknown but may include a herpes infection that lies dormant for a period before infecting the cells around the facial nerves. Any nerve damage that occurs can cause pain, and the level of paralysis depends on the extent of the damage. Facial nerve pain and numbness can occur in the ear, face, neck, or tongue.
Your dentist will first work with your doctor to diagnose the cause of your facial nerve pain before beginning treatment. Any underlying causes that are not addressed will potentially block the effectiveness of your treatments. For mild to moderate facial nerve pain, your dentist may recommend a period of rest, over-the-counter analgesics like ibuprofen, and a hot or cold compress.
This may be all that you need to feel better. This does not address any underlying conditions but may provide temporary relief of pain.
For sinus pain or pain associated with an injured or extracted tooth, your dentist may look for signs of infection or other complications. These can be treated with a course of antibiotics as needed. Antispasmodics, tricyclic antidepressants, and some anticonvulsants can also help relieve pressure on your facial nerves to prevent, decrease, or eliminate pain.
Your dentist may work with your doctor to make sure that these medications do not interact negatively with other treatments. Your dentist may also use Botox to help relieve facial nerve pain. Botox botulinum toxin A injections are placed into strategic areas of your jaw to relax and release tense temporalis or masseter muscles.
These injections will not affect speech or eating but can relieve pressure on the trigeminal nerve. Many patients may incorrectly attribute their symptoms to trauma or dental work. Patients with atypical facial nerve pain suffer from depression and anxiety in higher numbers than the general population.
Your dentist and doctor will work closely together to develop a plan to treat all of your symptoms concurrently. If you are looking for a dentist in the Phoenix area who can treat your facial nerve pain, give AZ Dentist a call. From diagnosis to treatment, we can help. Sleep Disorders. Facial Nerve Pain. What is facial nerve pain? These include that: Upper ophthalmic branch: Enervates the scalp, forehead, and front of the head Middle maxillary branch: Enervates the cheek, upper jaw, top lip, teeth and gums, and the side of the nose Lower mandibular branch: Enervates the lower jaw, teeth and gums, and bottom lip Facial nerve pain is pain referred by these nerves to the brain from any of these areas.
What causes facial nerve pain? Sinus infection Sinus infection usually comes with excess fluid that places pressure on the ophthalmic branch of the trigeminal nerve. H3: Trigeminal neuralgia Trigeminal neuralgia is a serious chronic pain condition that can affect the daily life of sufferers. Facial nerve pain after tooth extraction While a tooth extraction is a common and straightforward procedure, there can be lingering facial nerve pain after tooth extraction.
Trigeminal Neuralgia - What You Need to Know
The hallmark issue of Neurofibromatosis Type 2 NF2 is the bilateral growth of schwannoma bilaterally on cranial nerve 8 CN8 , the nerve in the brain vestibulocochlear nerve.
CN8 has two branches of different function the cochlear auditory nerve branch for hearing and the vestibular nerve branch for balance. These tumors are either called acoustic neuroma AN or vestibular schwannoma VS.
The growth of a VS does not guarantee damage to the cranial nerve 7 the facial nerve but is a possible risk. CN7 leaves the brainstem close to CN8. A surgical method, the Mid Fossa Approach. The approach to removing a VS for hearing preservation requires cutting the facial nerve. Radiation Treatment. Radiation treatments to cause tumor death of a VS can also kill the function of nerves and other components in the surrounding area.
Radiation treatments to cause tumor death of a VS can damage the facial nerve when the tumor commonly swells within the first month before shrinks with tumor death. CN7 damage and Cranial Nerve Schwannoma [Rare cranial nerve schwannomas, ] Facial nerve damage, damage to CN7, is not only the possible result of a tumor or treatment of a tumor on CN8 but could also be the result of tumor growth on CN7. The hallmark location of NF2 schwannoma growth is bilaterally along CN8. Other common locations or schwannoma growth in individuals with NF2 include:.
Vestibular Schwannoma, are Schwannoma tumors along Cranial Nerve 8, are an issue that develops in many individuals with NF2. Cranial Nerve 8 travels a similar path as Cranial Nerve 7, the Facial Nerve, extending out of the brainstem right next to each other. The purpose of CN8 is hearing and balance. The facial nerve branches off to smaller nerves and muscles that go to 5 different parts of the face.
Therefore, when the nerve is damaged those smaller veins are not supplied with enough blood for circulation which is necessary for muscles in the different areas of the face to move. Each nerve branch affects the movement of different muscles.
The nerves in the picture on the right show where on the face, outside of the skull, that the nerve branch extends out. The X in the image is pointing is the approximate location where the nerve extends outside of the skull, before branching to the different parts of the face. Damage to nerves that are a part of the central nerve system CNS , cranial nerves and spinal cord, do not heal as completely or easily as other nerves in the body. But some things can be done to help the nerve heal to consider following nerve damage.
Expect no noticeable signs of healing before about four to six months after the damage occurs. The nerve damage will never completely restore on its own, but there are some options to consider to help maximize the amount of healing. Remember, moderation with all food and supplement options. Excess of any food or supplement can have dangerous consequences. It is important to discuss all forms of physical therapy for facial paralysis and expectations with a physical therapist.
Exercises and treatments help encourage nerve stimulation, even if it takes months before signs of improvement appear. They can provide the patient with a specific set of exercises that are appropriate for their unique presentations. Acupuncture helps to stimulate blood to flow back to the different nerves in the face to encourage movement. If damage to the facial nerve the result of surgical intervention to remove a VS, it might be possible to reattach the nerve to either CN12 hypoglossal nerve, or CN5 trigeminal nerve during the surgery to remove the tumor.
A Free Muscle Transplant is when a healthy "extra" muscle and transplanting it somewhere else in the body. The muscle can be used anywhere but needs to be attached somewhere with a working nerve.
Years after the facial nerve is damaged, you may want to consider Facial Reanimation surgery depending on how much has of the nerve has recovered or not. In this procedure, the area the surgery happened is reopened from the ear down to the chin under the jaw bone. The nerve is reconnected to raise the droop in the face. There are different methods for this, talk to your doctors. While looking for options for movement on the side with the facial paralysis, individuals may also be looking for limitations of movement on the other side, to prevent Forehead Wrinkling.
BOTOX for paralysis patients is something insurance will cover and is something to consider, but it is also important to know risks. If the side effects listed develop, first response may need to be to discontinue the treatment before considering other health issues as the cause.
Talk to your doctor. The effect is that it temporarily weakens or paralyzes the facial muscles and smooths or eliminates wrinkles in the skin for a few months. It may cause dangerous issues like; swallowing or breathing problems. These problems can happen hours to weeks after the injection and can cause death. The risk is greatest in children who are being treated for muscle spasticity in their necks.
But adults who already have swallowing or breathing problems are also at risk for problems from a Botox injection. Other reasons for possible swallowing issue include tumor growth on the; lower branch of Trigeminal Nerve Cranial Nerve 5 the Mandibular branch , or 2 Vagus Nerve Cranial Nerve A tumor on the Vagus Nerve could also result in breathing issues.
Tumors that grow on the nerves that affect hearing and balance tend to push on the Facial Nerve which follows a similar path inside the brain.
During different tumor management techniques used to preserve hearing and balance the Facial Nerve is lost. Focused Radiation treatments can damage nerves in the surrounding area, but different Microsurgery surgery techniques to remove VS are less likely to damage the Facial Nerve.
However, if the tumor is already affecting the Facial Nerve, the chance of saving the nerve regardless of treatment choice would be minimal. Learn about NF2 Eye Issues. The Facial nerve does not control all of the functions of the face. Cranial Nerve 5, the Trigeminal Nerve which includes the following three 3 branches:.
Pain or any other feeling, numbness or lack of feeling in the face is the result of damage to Cranial Nerve 5 CN5 , the Trigeminal Nerve. Education is the Key.
