The 7th cranial nerve. The facial nerve has two parts, the larger motor root which may be called the facial nerve proper, and the smaller intermediate or sensory root. Together they provide efferent innervation to the muscles of facial expression and to the lacrimal and SALIVARY GLANDS, and convey afferent information for TASTE from the anterior two-thirds of the TONGUE and for TOUCH from the EXTERNAL EAR.
Diseases of the facial nerve or nuclei. Pontine disorders may affect the facial nuclei or nerve fascicle. The nerve may be involved intracranially, along its course through the petrous portion of the temporal bone, or along its extracranial course. Clinical manifestations include facial muscle weakness, loss of taste from the anterior tongue, hyperacusis, and decreased lacrimation.
Traumatic injuries to the facial nerve. This may result in FACIAL PARALYSIS, decreased lacrimation and salivation, and loss of taste sensation in the anterior tongue. The nerve may regenerate and reform its original pattern of innervation, or regenerate aberrantly, resulting in inappropriate lacrimation in response to gustatory stimuli (e.g., "crocodile tears") and other syndromes.
Severe or complete loss of facial muscle motor function. This condition may result from central or peripheral lesions. Damage to CNS motor pathways from the cerebral cortex to the facial nuclei in the pons leads to facial weakness that generally spares the forehead muscles. FACIAL NERVE DISEASES generally results in generalized hemifacial weakness. NEUROMUSCULAR JUNCTION DISEASES and MUSCULAR DISEASES may also cause facial paralysis or paresis.

Electrical stimulation as a therapeutic option to improve eyelid function in chronic facial nerve disorders. (1/372)

PURPOSE: To establish whether it is possible to improve orbicularis oculi muscle function in the eyelids of patients with a chronic seventh cranial nerve palsy by using transcutaneous electrical stimulation to the point at which electrical stimulation induces a functional blink. METHODS: Ten subjects (one woman, nine men) aged 36 to 76 with chronic, moderate to severe facial nerve palsy were recruited into the study. Voluntary and spontaneous eyelid movements were assessed, using an optical measuring system, before, during, and after a 3-month treatment period. Voluntary and spontaneous lid velocities were also measured and compared with eyelid kinematic data in normal subjects (12 women, 18 men; age range, 22-56 years). RESULTS: Therapeutic electrical stimulation applied over 3 months produced improvement in eyelid movement (>2 mm) in 8 of 10 patients during voluntary eyelid closure. However, there was no significant improvement recorded in spontaneous blink amplitudes or peak downward-phase velocity of the upper eyelid. This regimen of stimulation failed to recover function well enough that a functional blink could be induced in the paretic eyelid by electrical stimulation. CONCLUSIONS: Electrical stimulation using transcutaneous electrical nerve stimulators units can improve voluntary eye closure, apparently because of a reduction in stiffness of eyelid mechanics, rather than an improvement of muscle function. Investigation of alternative stimulation regimens is warranted.  (+info)

Spontaneous CSF otorrhea caused by abnormal development of the facial nerve canal. (2/372)

In two patients with surgically proved CSF fistula through the facial nerve canal, MR and CT examinations showed smooth enlargement of the geniculate fossa with CSF signal. In the clinical setting of CSF otorrhea or rhinorrhea, the presence of an enlarged labyrinthine facial nerve canal and enlarged geniculate fossa on CT scans and CSF intensity on MR images strongly suggests a CSF fistula through the facial nerve canal.  (+info)

Postcontrast T1-weighted MR images in a patient with Ramsay Hunt syndrome showed an enhancing lesion in the region of the nucleus of the pontine facial nerve and abnormal enhancement of the intrameatal, labyrinthine, and tympanic facial nerve segments and of the geniculate ganglion, as well as enhancement of the vestibulocochlear nerve and parts of the membranous labyrinth. This enhancement most probably resulted from a primary neuritis of the intrameatal nerve trunks of the seventh and eighth cranial nerves.  (+info)

Cardiac inotropic, chronotropic, and dromotropic actions of subretrofacial neurons of cat RVLM. (4/372)

The cardiac actions of microinjecting sodium glutamate (0.5-2 nmol) among sympathetic premotor neurons of the subretrofacial nucleus in the rostral ventrolateral medulla (RVLM) were studied in chloralose-anesthetized cats after bilateral vagotomy, sinoaortic denervation, adrenalectomy, and alpha1-receptor blockade. Glutamate microinjections increased heart rate by 25.9 +/- 1.8 beats/min (17. 5%), systolic rate of rise in left ventricular pressure (LVdP/dt) by 1,443 +/- 110 mmHg/s (119%), and arterial blood pressure by 26.9 +/- 1.7 mmHg (50%), whereas they shortened the electrocardiogram P-R interval in 85 of 103 cases by 7.5 +/- 1.2 ms (11.4%), triggering junctional rhythms on five occasions. The increase in LVdP/dt usually led the rise in blood pressure, and its magnitude greatly exceeded any increase attributable to changes in heart rate, diastolic filling, or afterload. Right-sided microinjections caused significantly greater tachycardias than did left-sided microinjections, but only left-sided microinjections triggered junctional rhythms (5 of 52 vs. 0 of 51; P < 0.05), whereas microinjections on either side raised LVdP/dt equally. Subretrofacial neurons thus drive positive chronotropic, inotropic, and dromotropic actions via the cardiac sympathetic nerves, whereas subsets among them preferentially control different aspects of cardiac function.  (+info)

Isolated dysarthria due to extracerebellar lacunar stroke: a central monoparesis of the tongue. (5/372)

OBJECTIVES: The pathophysiology of dysarthria can preferentially be studied in patients with the rare lacunar stroke syndrome of "isolated dysarthria". METHODS: A single study was carried out on seven consecutive patients with sudden onset of isolated dysarthria due to single ischaemic lesion. The localisation of the lesion was identified using MRI. The corticolingual, cortico-orofacial, and corticospinal tract functions were investigated using transcranial magnetic stimulation. Corticopontocerebellar tract function was assessed using 99mTc hexamethylpropylene amine oxime-single photon emission computerised tomography (HMPAO-SPECT) in six patients. Sensory functions were evaluated clinically and by somatosensory evoked potentials. RESULTS: Brain MRI showed the lesions to be located in the corona radiata (n=4) and the internal capsule (n=2). No morphological lesion was identified in one patient. Corticolingual tract function was impaired in all patients. In four patients with additional cortico-orofacial tract dysfunction, dysarthria did not differ from that in patients with isolated corticolingual tract dysfunction. Corticospinal tract functions were normal in all patients. HMPAO-SPECT showed no cerebellar diaschisis, suggesting unimpaired corticopontocerebellar tract function. Sensory functions were not affected. CONCLUSION: Interruption of the corticolingual pathways to the tongue is crucial in the pathogenesis of isolated dysarthria after extracerebellar lacunar stroke.  (+info)

MR imaging of Dejerine-Sottas disease. (6/372)

We report the MR findings in two patients with clinically and histologically proved Dejerine-Sottas disease. One patient had spinal involvement with multiple thickened and clumped nerve roots of the cauda equina; the second had multiple enlarged and enhancing cranial nerves. Although these findings are not specific for Dejerine-Sottas disease, they are suggestive of the diagnosis, which is further corroborated with history and confirmed with sural nerve biopsy and laboratory studies.  (+info)

Hoxa2 and Hoxb2 control dorsoventral patterns of neuronal development in the rostral hindbrain. (7/372)

Little is known about how the generation of specific neuronal types at stereotypic positions within the hindbrain is linked to Hox gene-mediated patterning. Here, we show that during neurogenesis, Hox paralog group 2 genes control both anteroposterior (A-P) and dorsoventral (D-V) patterning. Hoxa2 and Hoxb2 differentially regulate, in a rhombomere-specific manner, the expression of several genes in broad D-V-restricted domains or narrower longitudinal columns of neuronal progenitors, immature neurons, and differentiating neuronal subtypes. Moreover, Hoxa2 and Hoxb2 can functionally synergize in controlling the development of ventral neuronal subtypes in rhombomere 3 (r3). Thus, in addition to their roles in A-P patterning, Hoxa2 and Hoxb2 have distinct and restricted functions along the D-V axis during neurogenesis, providing insights into how neuronal fates are assigned at stereotypic positions within the hindbrain.  (+info)

Exacerbation of facial motoneuron loss after facial nerve transection in severe combined immunodeficient (scid) mice. (8/372)

The immune system functions to protect an organism against microbial infections and may be involved in the reparative response to nerve injury. The goal of this study was to determine whether the immune system plays a role in regulating motoneuron survival after a peripheral nerve injury. After a right facial nerve axotomy, facial motoneuron (FMN) survival in C.B-17 (+/+) wild-type mice was found to be 87 +/- 3.0% of the unaxotomized left side control. In contrast, facial nerve axotomy in C.B-17 (-/-) severe combined immunodeficient (scid) mice, lacking functional T and B lymphocytes, resulted in an average FMN survival of 55 +/- 3.5% relative to the unaxotomized left side control. This represented an approximately 40% decrease in FMN survival compared with wild-type controls. The reconstitution of scid mice with wild-type splenocytes containing T and B lymphocytes restored FMN survival in these mice to the level of the wild-type controls. These results suggest that immune cells associated with acquired immunity play a role in regulating motoneuron survival after a peripheral nerve injury.  (+info)

The facial nerve is the seventh cranial nerve, or simply cranial nerve VII. It emerges from the brainstem between the pons and the medulla, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue and oral cavity. It also supplies preganglionic parasympathetic fibers to several head and neck ganglia. The facial and intermediate nerves can be collectively referred to as the nervus intermediofacialis. The path of the facial nerve can be divided into six segments. intracranial (cisternal) segment meatal segment (brainstem to internal auditory canal) labyrinthine segment (internal auditory canal to geniculate ganglion) tympanic segment (from geniculate ganglion to pyramidal eminence) mastoid segment (from pyramidal eminence to stylomastoid foramen) extratemporal segment (from stylomastoid foramen to post parotid branches) The motor part of the facial nerve arises from the facial nerve nucleus in the pons while the ...

Objective: This literature review analysed facial nerve management strategies in jugular paraganglioma surgery and discusses the tumour resection rate and the facial nerve outcome associated with each technique. Methods: A retrospective review of PubMed and Medline articles on the surgical treatments for jugular paraganglioma was performed. Tumour resection rates and post-operative facial nerve function after non-rerouting, short anterior rerouting and long anterior rerouting approaches were evaluated for each article. Results: A total of 15 studies involving a total of 688 patients were included. Post-operative facial nerve function was similar after non-rerouting and short anterior rerouting approaches (p = 0.169); however, both of these techniques had significantly better post-operative facial nerve outcomes compared with long anterior rerouting (p , 0.001 and p = 0.001, respectively). The total tumour removal rate was significantly higher for long anterior rerouting than with the ...

What is the definition of FACIAL NERVE? What is the meaning of FACIAL NERVE? How do you use FACIAL NERVE in a sentence? What are synonyms for FACIAL NERVE?
Causes of facial nerve damage are injury to the seventh cranial nerve. Symptoms of facial nerve damage are facial palsy and partial loss of sensation of taste.
A nerve decompression surgery where abnormal compression on the facial nerve is relieved is known as facial nerve decompression.. Compression and pressure of any cause on a peripheral nerve can cause blockage of the nerve impulse. This means that the nerve can no longer send electrochemical impulses and hence does not send signals to the brain or from the brain to the muscles.. There might also be loss of the nerves myelin sheath and degeneration of the nerve in the area affected, but it does not affect axons beyond this site.. The facial nerve is a mixed nerve with sensory and motor nerve fibers, and hence compression can create sensory and motor deficits. ...

Article Type: Research Article Abstract: BACKGROUND AND OBJECTIVES: Early persistent facial paralysis is characterized by intact muscles of facial expression through maintained perfusion but lacking nerve supply. In facial reanimation procedures aiming at restoration of facial tone and dynamics, neurotization through a donor nerve is performed. Critical for reanimating target muscles is axonal capacity of both donor and recipient nerves. In cases of complete paralysis, the proximal stump of the extratemporal facial nerve trunk may be selected as a recipient site for coaptation. To further clarify the histological basis of this facial reanimation procedure we conducted a human cadaver study examining macro and micro anatomical …features of the facial nerve trunk including its axonal capacity in human cadavers. Axonal loads, morphology and morbidity of ...
The facial nerve is necessary for our ability to eat, speak, and make facialgestures. To perform these vital functions, the nerve must accurately navigate from the hindbrain to the correct muscles during embryonic development. In the development of the facial nerve, both the cell bodies and the axons undergo specific migration patterns to assemble central neuron patterns and peripheral nerve projections to target muscles. Our goal in this study was to define the molecular signals by which the facial cell bodies and their axons correctly make this long journey. By analyzing facial neuron migration patterns in mouse embryos carrying mutations in the chemorepulsive receptors Robo1 and Robo2, we found that these proteins are necessary for guiding the cell bodies and axons of the branchiomotor aspect of the facial nerve.

A crucial part of nervous system development in vertebrate embryos is migration of neurons from initial birth-place to final destinations within the brain. The migration trajectories are fundamental to proper brain wiring. Recently we showed that within the neurons of the facial nerve, a single pioneer neuron guides movement of the remaining neurons. Basic questions remain: Where do pioneer neurons come from, how do they know where to go, and how do other neurons know how to follow them? We are studying the pioneer neurons that lead facial branchiomotor neurons (FBMNs) of zebrafish embryos via light-sheet microscopy imaging. Technical and scientific challenges drive our visualization research. Imaging one embryo (over about 8 hours) generates a terabyte of two-channel image data (GFP for nuclei, RFP for cell membranes). The data size and the ventral location of the FBMN (limiting image quality) impede simple application of existing automated cell trackers. The two FBMN pioneers can be ...

Now, I have not gone into detail much online, other than a whittled-down list of folks on my Facebook page who are my prayer warriors, close friends and family members. But I had major ear surgery last week at Fort Lewis, Washington. I had a growth that distorted my eardrum, destroyed much of my temporal bone all the way up to my brain, began to expose my facial nerve, damaged a taste nerve, and destroyed two of the three bones needed for hearing. I now have a new reconstructed eardrum, no disease, and my facial nerve, perilously close to being exposed and damaged, is getting some steroids for strength and protection. I still have hearing in my ear--its all sensorineural, as those parts are still in working order. My hearing loss will be able to be fixed next year (should the disease not return) with the insertion of a titanium implant replacing the two destroyed hearing bones, connecting my new eardrum to the stapes bone ...

He is at the beginning and the end of it. But to be more specific, people have prayed for a speedy recovery. One prayer requested of God that when the surgeons got in there, they would, say Hey! Somebody has been in here before us. Well, the angiogram found almost nothing to embolize. This made it much easier to work on the tumor. What happened to the blood supply that grew that tumor so big? God. Secondly, the MRI shows with obvious detail that the tumor had a sticky character. It wasnt sticky; should have been, but it wasnt. Why not? God. The tumor has invaded the cranial nerves responsible for facial motor function, swallowing and some others that have been mentioned in the pages of this blog somewhere. Removing the tumor from them would be destructive and require weeks and weeks of rehabilitation. It was not necessary to remove the tumor from around those nerves, so Tracy has pretty good function all around. I have explained before that enough of the tumor was removed that what is left ...
Two central nervous system origins are customarily ascribed to each cranial nerve: 1.) Superficial origins are from the surface of the central nervous system, while 2.) Deep origins are from cell bodies and nuclei within the central nervous system (30). The general location and approximate number of rootlets of origin for cranial nerves have been well described in standard anatomy texts (31). Contrariwise, descriptions of the interconnections of these rootlets are not readily found. Bischoff published such a study in 1865 (32). Fragmentary descriptions of individual nerve connections often have been found only scattered throughout the literature. For example, Hovelaque (33) quotes earlier authors Hirshfield and Sappy in their descriptions of variations in interconnections of the ansa of von Haller, also called the nerve of Jacobson, lying between the hypoglossal and facial nerves. As another example of a variable interconnection observed in our laboratory, in one subject, the rootlets of the ...
Surgery on Facial Scars. When the skin is in the process of recovering from an injury, whether the result of an accident, tumor, surgery, a burn, or acne, scarring will occur wherever multiple layers of the skin have been affected. Once a scar forms, it is permanent but may be made less visible or relocated surgically.. With very few exceptions most people are self-conscious about facial scars. Some people may also experience diminished functioning of the eyes, mouth, or nose due to scarring. If youve wondered how facial scar revision could improve your appearance, your self-confidence, or your level of facial functioning, you need to know how scar revision works and what you can expect from this procedure. This pamphlet can address many of your and provide you the information to begin considering facial scar revision surgery.. A person considering facial scar revision must understand that there is no way to remove scars completely. The goal is to improve the appearance of the scar either by ...
