Trigeminal Neuralgia: Cranial Nerve Disorders: Merck Manual Home Edition Trigeminal neuralgia (tic douloureux) is pain due to malfunction of cranial nerve V (trigeminal nerve), which carries sensory information from the face to the brain and controls the muscles involved in chewing. A common known cause is an abnormally positioned artery that compresses the trigeminal nerve near where it exits the brain. However, doctors must distinguish trigeminal neuralgia from other possible causes of facial pain, such as disorders of the jaw, teeth, or sinuses and trigeminal neuropathy (which is often due to compression of the trigeminal nerve by a tumor or an aneurysm). www.merck.com /mmhe/sec06/ch096/ch096d.html   (558 words)

Trigeminal neuralgia - WrongDiagnosis.com Trigeminal neuralgia, also called tic douloureux, is a condition that affects the trigeminal nerve (the 5th cranial nerve), one of the largest nerves in the head. Trigeminal neuralgia, or Tic Douloureux, is a neuropathic disorder of the trigeminal nerve that causes episodes of intense pain in the eyes, lips, nose, scalp, forehead, and jaw. Trigeminal neuralgia is considered by many to be among the most painful of conditions and has been labeled the "suicide disease," due to the significant numbers of people taking their own lives because they were unable to have their pain controlled with medications or surgery. www.wrongdiagnosis.com /t/trigeminal_neuralgia/intro.htm   (852 words)

CPMC Neurosurgery - Trigeminal Neuralgia (Tic Douloureux)   (Site not responding. Last check: 2007-11-06) Trigeminal neuralgia (also known as tic douloureux) is a facial pain syndrome that usually develops in individuals over 50 years old. The trigeminal nerve is also known as cranial nerve V. It transmits sensation from the face, eyes and teeth and controls the muscles of mastication (chewing). In younger patients, trigeminal neuralgia can be caused by tumors in the region of cranial nerve V or (more commonly) by multiple sclerosis. cpmcnet.columbia.edu /dept/nsg/NSGCPMC/specialties/trigeminal.html   (462 words)

NeurosurgeryToday.org | What is Neurosurgery | Patient Education Materials | trigeminal neuralgia The trigeminal nerve is the fifth of 12 pairs of cranial nerves in the head. According to the Trigeminal Neuralgia Association, 4.1 percent of patients with unilateral trigeminal neuralgia and 17 percent of patients with bilateral trigeminal neuralgia report a family history of the disorder. Microvascular decompression involves microsurgical exposure of the trigeminal nerve root, identification of a blood vessel that may be compressing the nerve, and gentle displacement of it away from the point of compression. www.neurosurgerytoday.org /what/patient_e/trigeminal.asp   (1755 words)

Trigeminal trophic syndrome: A report of two cases with review of literature Trigeminal trophic syndrome, a rare cause of facial ulceration, is the consequence of damage to the trigeminal nerve or its central sensory connections. Trigeminal trophic syndrome was first described by Wallenberg in 1901 as an uncommon clinical entity in which cutaneous trophic ulceration develops within trigeminal dermatomes [1]. Trigeminal trophic syndrome is a rare consequence of damage to the trigeminal nerve or its central sensory connection [2]. dermatology.cdlib.org /95/case_presentations/trigeminal/jellouli.html   (1144 words)

Trigeminal Neuralgia : the compression of the nerve   (Site not responding. Last check: 2007-11-06) TN (Trigeminal Neuralgia / tic douloureux) is a disorder of the fifth cranial (trigeminal) nerve that causes episodes of intense, stabbing, electric shock-like pain in the areas of the face where the branches of the nerve are distributed - lips, eyes, nose, scalp, forehead, upper jaw, and lower jaw. The trigeminal nerve is the fifth of twelve pairs of cranial nerves enervating the face and head, and is denoted by the Roman Numeral V. It has three divisions which enervate the forehead and eye (ophthalmic V1), cheek (maxillary V2) and lower face and jaw (mandibular V3). The pain of trigeminal neuralgia is due to a disturbance in the function of the trigeminal nerve, which carries sensation from the face to the brain. www.womenfitness.net /trigeminal_neuralgia.htm   (2032 words)

Trigeminal Neuralgia Treatment Trigeminal neuralgia (TN), also known as tic douloureux, is a pain syndrome recognizable by patient history alone. One theory suggests that peripheral injury or disease of the trigeminal nerve increases afferent firing in the nerve perhaps by ephaptic transmission between afferent unmyelinated axons and partially damaged myelinated axons; failure of central inhibitory mechanisms may also be involved. Thus, although trigeminal neuralgia typically is caused by a dysfunction in the peripheral nervous system (the roots or trigeminal nerve itself), a lesion within the central nervous system may rarely cause similar problems. www.neurosurgery.pitt.edu /imageguided/trigeminal_neuralgia.html   (1017 words)

Trigeminal Neuralgia Trigeminal neuralgia is one of the most painful conditions ever described; inducing crippling, shock-like stabbing and/or throbbing facial pain. Some authorities on cranial nerve conditions such as trigeminal neuralgia, suspect that compression of the trigeminal nerve by a vein or an artery is the main cause although direct injury to the trigeminal nerve, the 5th of the 12 pairs of cranial nerves, can also cause the onset of this type of neuralgia. This is thought to be due to demyelination of the trigeminal nerve nucleus within the brainstem, or the trigeminal nerve itself. www.themcfox.com /health/trigeminal-neuralgia/trigeminal-neuralgia.htm   (492 words)

Trigeminal Neuralgia / Stereotactic Radiosurgery Trigeminal neuralgia is characterized by sudden bursts (paroxysms) of face pain. The pain is in the areas supplied by the trigeminal nerve: the cheeks, jaw, teeth, gums, lips and less often around the eye or forehead. If he or she finds a blood vessel pressing on the trigeminal nerve, a soft piece of material will be placed between the blood vessel and the nerve, thus lifting the blood vessel away from the nerve. www.irsa.org /trigeminal_neuralgia.html   (1677 words)

Trigeminal Neuralgia Trigeminal neuralgia, also known as tic douloureux, is an inflammation of the trigeminal nerve causing extreme pain and muscle spasms in the face. Trigeminal neuralgia is a painful disorder of the fifth cranial nerve, called the trigeminal nerve. In this case, a portion of the trigeminal nerve root is cut at its connection with the brain. www.mayfieldclinic.com /PE-TRIN.htm   (2044 words)

Trigeminal Neuralgia Trigeminal neuralgia is a disorder of the trigeminal nerve, the 5th cranial nerve that carries sensations of touch, pain, pressure, and temperature from the face to the brain. Trigeminal neuralgia usually occurs after the age of 70 and is unusual in anyone under the age of 50. If trigeminal neuralgia is caused by an artery or tumor compressing the nerve, surgery may be needed to free the nerve from the source of pressure and permanently relieve the pain. www.hmc.psu.edu /healthinfo/t/trigeminalneuralgia.htm   (833 words)

Facial Neuralgia Resources: Trigeminal Neuralgia Trigeminal Neuralgia (TN), also known as Tic Douloureux, is considered by many to be the "most terrible pain known to man." The electric shock-like pain generally is on one side of the face and is spasmodic, coming in short bursts lasting a few seconds. Trigeminal Neuralgia is a disorder of the trigeminal nerve, one of twelve pairs of cranial nerves on each side of the head. The word "trigeminal" derives from the Latin word "tria" which means "three" and from "geminus" which means "twin" and refers to the fact that the trigeminal nerve has three distinct branches on each side of the head. facial-neuralgia.org /conditions/tn.html   (1610 words)

Pain Medicine & Palliative Care: Pain Medicine The primary symptom of trigeminal neuralgia is the sudden onset of severe, sharp facial pain, usually without warning. The trigeminal nerve is the fifth and largest of the brain's twelve nerves, carrying both motor and sensory messages from the face to the brain. Trigeminal neuralgia also can be activated by such conditions as multiple sclerosis, tumors and abnormal blood vessels. www.stoppain.org /pain_medicine/tri-neur.html   (1035 words)

Mayo Clinic: Treatment Options for Trigeminal Neuralgia Trigeminal neuralgia often follows a "remitting and relapsing course" in which some patients experience pain, have their pain controlled with medication, and then, after weeks or months, are weaned off the medication and remain pain-free. A needle is inserted into the trigeminal nerve at the base of the skull where the trigeminal nerve root exits the skull. In percutaneous balloon compression of the trigeminal nerve (PBCTN), a needle is inserted through the face and into the hole at the base of the skull where the trigeminal nerve exits. www.mayoclinic.org /trigeminal-neuralgia/treatment.html   (863 words)

Trigeminal Nerve   (Site not responding. Last check: 2007-11-06) The sensory root joins the trigeminal or semilunar ganglion between the layers of the dura mater in a depression on the floor of the middle crania fossa. The three sensory branches of the trigeminal nerve emanate from the ganglia to form the three branches of the trigeminal nerve. The sensory part of the mandibular nerve is composed of branches that carry general sensory information from the mucous membranes of the mouth and cheek, anterior two-thirds of the tongue, lower teeth, skin of the lower jaw, side of the head and scalp and meninges of the anterior and middle cranial fossae. www.meddean.luc.edu /lumen/MedEd/GrossAnatomy/h_n/cn/cn1/cn5.htm   (345 words)

Trigeminal neuralgia Encyclopedia of Medicine - Find Articles Trigeminal neuralgia is a disorder of the trigeminal nerve (the fifth cranial nerve) that causes episodes of sharp, stabbing pain in the cheek, lips, gums, or chin on one side of the face. The trigeminal nerve, which is divided into three branches, is responsible for chewing, for producing saliva and tears, and for sending facial sensations to the brain. The origin of trigeminal neuralgia is not certain, but scientists believe it may be caused by degeneration, pressure, or irritation of the trigeminal nerve. www.findarticles.com /p/articles/mi_g2601/is_0014/ai_2601001400   (785 words)

Trigeminal Neuralgia Information Page: National Institute of Neurological Disorders and Stroke (NINDS) Trigeminal neuralgia (TN), also called tic douloureux, is a chronic pain condition that causes extreme, sporadic, sudden burning or shock-like face pain that lasts anywhere from a few seconds to as long as 2 minutes per episode. The presumed cause of TN is a blood vessel pressing on the trigeminal nerve in the head as it exits the brainstem. TN may be part of the normal aging process but in some cases it is the associated with another disorder, such as multiple sclerosis or other disorders characterized by damage to the myelin sheath that covers certain nerves. www.ninds.nih.gov /disorders/trigeminal_neuralgia/trigeminal_neuralgia.htm   (663 words)

Trigeminal neuralgia The condition is called trigeminal neuralgia because the painful facial areas are those served by one or more of the three branches of your trigeminal nerve. The pain of trigeminal neuralgia is due to a disturbance in the function of the trigeminal nerve. The needle is guided into the trigeminal cistern, a small sac of spinal fluid that surrounds the trigeminal nerve ganglion (the area where the trigeminal nerve divides into three branches) and part of its root. www.cnn.com /HEALTH/library/DS/00446.html   (1950 words)

eMedicine - Trigeminal Neuralgia : Article by Kim J Burchiel, MD, FACS Trigeminal neuropathic pain (TNP): This is pain that results from incidental or accidental injury to the trigeminal nerve or the brain pathways of the trigeminal system. Pathophysiology: Vascular compression of the trigeminal nerve appears to cause demyelination and remyelination of the nerve with persisting abnormalities of myelination (dysmyelination). Trigeminal tractotomy (cutting of the descending trigeminal tract in the medulla), retrogasserian glycerol instillation in trigeminal cistern, peripheral alcohol blocks, and partial trigeminal rhizotomy via a posterior fossa craniotomy are other rarely used options. www.emedicine.com /med/topic2899.htm   (3879 words)

A Shocking Development: The Pains Of Trigeminal Neuralgia Trigeminal Neuralgia is a sharp, lightning-quick pain which one experiences on the side of the face. For people with trigeminal neuralgia, they complain of pain that coarses through the branches of the trigeminal nerve along the side of his face. Often, people with trigeminal neuralgia go to their dentist, thinking their pain is from either a toothache or a cavity. www.personalmd.com /news/trigeminalneuralgia_1211000.shtml   (552 words)

Trigeminal Neuralgia   (Site not responding. Last check: 2007-11-06) Trigeminal Neuralgia (TN), or "Tic Douloureux" is characterized by intermittent, shooting pain in the face. The most common cause of Trigeminal Neuralgia is an enlarged looping artery or vein pressing on the Trigeminal nerve at the base of the brain. The trigeminal nerve is easily visualized in the axial plane when the MRI series is centered at the midpoint of the fourth ventricle. www.neurosurgery.ucsd.edu /cnd/trigeminal_neuralgia.htm   (1043 words)

Trigeminal Neuralgia - Patient UK Trigeminal neuralgia (TN) is a condition that causes recurring severe pains in parts of your face. The trigeminal nerve (also called the fifth cranial nerve) is one of the main nerves of the face. Basically, the aim of surgery is to ease any pressure at the root of the trigeminal nerve (which is often caused by pressure from nearby blood vessels). www.patient.co.uk /showdoc.asp?doc=23068947   (1271 words)

Trigeminal Neuralgia - Microvascular Decompression - MEDSTUDENTS - Neurosurgery He observed the almost universal occurrence of vascular channels compressing the trigeminal nerve in patients with TN and devised a technique for nondestructive microvascular decompression of the nerve. At the operation, the root entry zone of the trigeminal nerve was examined for vascular cross-compression in 21 patients. The Trigeminal reflex (corneal reflex, blink reflex, masseter inhibitory periods, jaw-jerk) have abnormalities (4).The corneal reflex may be decreased, especially in neuralgia of first division trigeminal nerve, and it may be decreased in only part of the cornea, especially the upper half. www.medstudents.com.br /neuroc/neuroc2.htm   (1743 words)
