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 ...

  • Idiopathic facial paralysis (Bell palsy) is the most common type. (
  • The etiology of the facial paralysis determines the likelihood of spontaneous return of function, as in most cases of idiopathic facial paralysis (Bell palsy). (
  • Most problems involving the facial nerve include paralysis, commonly with Bell's palsy . (
  • Bell's palsy is the term often given to reduced functioning or paralysis of the facial nerve. (
  • Facial nerve palsy due to birth trauma is the loss of controllable (voluntary) muscle movement in an infant's face due to pressure on the facial nerve just before or at the time of birth. (

  • The most common form of facial nerve palsy due to birth trauma involves only the lower part of the facial nerve. (
  • The proper use of forceps and improved childbirth methods have reduced the rate of facial nerve palsy. (
  • Bell's palsy disrupts the messages sent from the brain to the facial nerves causing paralysis and facial weakness. (
  • Now on a brighter note most who are afflicted with Bell's palsy make a full recovery within 3 to 6 months at which point functions of the facial nerves return to full function. (
  • There is different types of therapies to help with the recovery of Bell's palsy such as relaxation techniques, vitamin therapy (B-6,B-12, and zinc) these can help the nerve functions. (

  • Facial palsy has an annual incidence of approximately 20 per 100,000. (
  • The most important initial clinical task in evaluating a patient with facial palsy is to differentiate a central facial palsy from a peripheral palsy. (
  • In central or upper motor neuron facial palsy, the upper part of the face or the forehead is spared because of bilateral innervation from the motor cortex to each CN VII nucleus. (
  • Causes for facial palsy may be genetic or acquired. (
  • Did the facial palsy occur during warm months? (
  • Is there recurrent facial palsy - with fissured tongue, facial edema, similar family history? (
  • Is there history of recurrent, ipsilateral facial palsy, suggesting neoplasm? (
  • In congenital facial nerve palsy, computed tomography (CT) scan of temporal bone with thin internal auditory canal can be helpful to assess middle and or inner-ear anomalies and to rule out absence or dysplasia of the facial nerve. (
  • In acquired facial palsy, magnetic resonance imaging (MRI), with and without contrast, is helpful to look at brain stem, pons, the cerebellopontine angle and the internal auditory canal. (
  • If forehead is spared, suggesting a central facial nerve palsy, the patient needs immediate imaging and evaluation for stroke. (
  • According to Babak Azizzadeh, MD, FACS, and director of the FacialParalysis Institute in Beverly Hills, the new advance could greatly reduce the number of patientswho experience post-operative muscle palsy, also described as temporary facial paralysis. (

  • Other signs may be linked to the cause of the paralysis, such as vesicles in the ear, which may occur if the facial palsy is due to shingles. (
  • Lyme disease, an infection caused by Borrelia burgdorferi bacteria and spread by ticks, can account for about 25% of cases of facial palsy in areas where Lyme disease is common. (
  • In up to 10-15% of Lyme infections, facial palsy appears several weeks later, and may be the first sign of infection that is noticed, as the Lyme rash typically does not itch and is not painful. (
  • Reactivation of herpes zoster virus, as well as being associated with Bell's palsy, may also be a direct cause of facial nerve palsy. (
  • In the case of inflammation the nerve is exposed to edema and subsequent high pressure, resulting in a periferic type palsy. (

  • Symptoms of facial nerve palsy are hemifacial paresis of the upper and lower face. (
  • Treatment may include lubrication of the eye, intermittent use of an eye patch, and, for idiopathic facial nerve palsy, corticosteroids. (
  • Historically, Bell palsy was thought to be idiopathic facial nerve (peripheral 7th cranial nerve) palsy. (
  • However, facial nerve palsy is now considered a clinical syndrome with its own differential diagnosis, and the term 'Bell palsy' is not always considered synonymous with idiopathic facial nerve palsy. (
  • About half the cases of facial nerve palsy are idiopathic. (
  • The mechanism for what was previously thought to be idiopathic facial nerve palsy is presumably swelling of the facial nerve due to an immune or viral disorder. (
  • Various other disorders (eg, Lyme disease , sarcoidosis ) can cause facial nerve palsy. (
  • However, peripheral lesions (facial nerve palsy) tend to affect the upper face more than central lesions (eg, stroke) do. (

  • Facial nerve palsy occurs when the nerve controlling facial movements is damaged during birth. (
  • The most common cause of facial nerve palsy (sometimes referred to as Bell's Palsy) is trauma and while most cases cure themselves, the condition is permanent in some children and affects one side of their faces for the rest of their lives. (
  • The majority of facial nerve palsy affects the mouth and neighboring muscles but more severe cases can affect an entire side of the child's face, making it impossible for the child to open and close an eyelid, or move any muscle on the side of his or her face. (
  • If your child's face looks uneven when he or she cries or makes facial expressions, it is important to have the child examined by a doctor to determine the presence of facial nerve palsy. (

  • Trial design Hypoglossal-facial nerve (HN-FN) neurorrhaphy is a method commonly used to treat facial palsy when the proximal stump of the injured FN is unavailable. (
  • Since the classic HN-FN neurorrhaphy method that needs to section the injured FN is not suitable for incomplete facial palsy, we investigated a modified method that consists of HN-FN 'side'-to-side neurorrhaphy, retaining the remaining or spontaneously regenerated FN axons while preserving hemihypoglossal function. (
  • The three patients who experienced less satisfactory outcomes had exhibited facial palsy for more than 1 year accompanied by muscle atrophy, consistent with a need for rapid surgical intervention. (

  • Facial palsy is a relatively common clinical condition with a variety of causes. (
  • Irrespective of its etiology, facial palsy always represents a very serious problem for the patient. (
  • Retrospective evaluation of a clinical material of 16 patients with facial palsy treated at the University Hospital of Linköping during the period 1990-2000 showed that to improve the results of microsurgical nerve repair experimental research - controlled studies on homogeneous materials - is imperative. (
  • The symptoms include inflammation of the eye (uveitis), swelling of the parotid gland, chronic fever, and in some cases, palsy of the facial nerves. (
  • In patients that have already been diagnosed with sarcoidosis, Heerfordt syndrome can be inferred from the major symptoms of the syndrome, which include parotitis, fever, facial nerve palsy and anterior uveitis. (

  • a very useful use of Botox is in treatment of facial nerve paralysis. (
  • OBJECTIVE The pathophysiology and treatment of facial nerve paralysis associated with acute otitis media are still under debate. (
  • Neoplastic causes of facial paralysis include tumors of the parotid gland, typically malignant. (
  • The facial nerve then enters the parotid gland between the stylohyoid and digastric muscle. (
  • Causes of facial nerve paralysis include head trauma, infection or inflammation of the facial nerve, parotid tumors, head or neck cancers, or stroke. (
  • The facial nerve divides the parotid gland into superficial and deep lobes. (
  • The facial nerve then passes through the parotid gland, which it does not innervate, to form the parotid plexus, which splits into five branches (temporal, zygomatic, buccal, marginal mandibular, and cervical) innervating the muscles of facial expression. (
  • Occasionally, lesions in the parotid gland or in the vicinity of the upper mandible also may lead to acute facial nerve paralysis. (
  • The vast majority of benign tumors of the cerebellopontine angle, temporal bone, and parotid gland can be successfully resected without permanent injury to the facial nerve. (
  • Facial paralysis can arise for many reasons: previous trauma, cancers like parotid tumors, acoustic neuromas, facial nerve tumors, etc. (
  • The facial nerve controls facial expression and movement and passes directly through the parotid gland, an organ that enables verbal and non-verbal communication. (
  • This nerve exits the stylomastoid foramen and enters the core of the parotid gland. (
  • Within the parotid gland, the facial nerve splits into an upper and lower division. (
  • When a patient develops a parotid tumor, in most cases the tumor grows next to or on top of the facial nerve. (
  • And it is not until surgery begins that you can actually see where the facial never is in relation to the parotid tumor. (
  • This makes surgery to remove the parotid tumor very complex and requires a facial nerve expert to ensure the nerve is preserved and not damaged during the surgery. (
  • When it comes to parotid surgery, it is important to work with the best team of head and neck surgeons facial plastic and reconstructive surgeons available. (

  • A primary irritation of the facial nerve nucleus or increased excitability of the facial nucleus by upper motor neuron dysfunction can also cause hemifacial spasm. (
  • Conclusion: Functional training of facial mimic muscles cannot shorten the time of recovery for the patients with minor facial nerve injury but it can speed up the recovery and reduce the undesirable sequelae such as synkinesis and hemifacial spasm for the patients with moderate and severe facial nerve injury. (
  • This may involve all or selected branches of the facial nerve. (
  • For nerve injuries where the injured branches of the facial nerve can be identified, nerve grafting is the first choice of treatment. (
  • Minor differences in the structure and location of the branches of the facial nerve are not usually noticeable. (
  • When someone moves on the partially paralyzed side, multiple branches of the facial nerve can pull at once making the individual look abnormal. (
  • A recent study published in Muscle & Nerve appears to show that needle electromyography can play a major role in reinnervation in face transplantation. (
  • Terzis JK, Karypidis D. Outcomes of direct muscle neurotisation in adult facial paralysis. (
  • Bone marrow-derived mesenchymal stem cell transplantation does not improve quality of muscle reinnervation or recovery of motor function after facial nerve transection in rats. (
  • Clinically, upper motor neuron lesions result in muscle sparing in the upper portion of the face but involvement of the lower two thirds of the facial mimetic musculature. (
  • For patients who do not recover from facial paralysis after one year, treatments including the masseteric-facial nerve transfer and cross-facial nerve graft with gracilis muscle flap have really created a significant positive impact. (
  • Facial slings and muscle transfer techniques are used to support to corner of the mouth and lower face. (
  • Whereas facial slings are "static" and do not move, muscle transfer techniques can result in dynamic movement restoring patients ability to smile. (
  • Nevertheless, facial muscles lack muscle spindles, but the facial proprioception plays key roles in the regulation and coordination of facial musculature and diverse reflexes. (
  • Substituting muscle spindles facial muscles contain other kinds of proprioceptors of variable morphology that display immunoreactivity for some putative mechanoproteins known to participate in proprioception (acid-sensing ion channel 2, transient receptor potential vanilloid 4, and Piezo2). (
  • These procedures do require a lot of commitment from patients because nerves grow slowly, and just connecting the nerve surgically or transplanting a muscle is only half the battle. (
  • The temporal nerve controls the frontalis muscle. (
  • The mandibular nerve controls the mentalis muscle. (
  • The cervical nerve controls the platysma, and the posterior auricular nerve controls the occipitalis muscle. (
  • Peripheral nerve hyperexcitability syndrome comprises a heterogeneous group of diseases, clinically characterised by myokymia, fasciculation, muscle cramps and stiffness. (
  • As a result of this research, Diana developed Trophic Electrical Stimulation, in which frequencies copied from normal nerves are used to improve nerve and muscle function in people with nerve damage. (
  • Dr. Lam refers back to previous treatment strategies but always reassesses the situation because muscle tone and facial shape do change over time. (
  • In the prognosis of facial paralysis the aetiological and time factors involved, the completeness of paralysis, muscle tone and electrical tests are most important. (
  • The treatment group started training facial mimic muscle activity 2 weeks after facial nerve injury. (
  • The chip in the good eye can detect either nerve function or muscle movement whenever that eye blinks," Mickle explained. (
  • Neurotization of such muscle unit can be obtained from different sources, the most frequent being the contralateral facial nerve via cross-face nerve graft (CFNG) or the motor nerve to the masseter. (
  • High-resolution computed tomographic features of the stapedius muscle and facial nerve in chronic otitis media. (
  • The internal auditory canals as well as the vestibulo-cochlear nerve complexes appear unremarkable. (
  • Most commonly, facial paralysis follows temporal bone fractures, though the likelihood depends on the type of fracture. (
  • Upper motor neuron lesions of the facial nerve occur at any point from the motor cortex proximal to the facial nucleus. (
  • Traumatic facial paralysis (from blunt and penetrating trauma or intraoperative iatrogenic injury) is the next most common type. (
  • It is a type of facial paralysis that happens when there is some type of damage or trauma to the facial nerves. (
  • Is there h/o facial trauma? (
  • Is there a history of facial trauma? (
  • In blunt trauma, the facial nerve is the most commonly injured cranial nerve. (
  • Understandably, the likelihood of facial paralysis after trauma depends on the location of the trauma. (
  • His antenatal scans had been normal and he was born in good condition by emergency caesarean section for antepartum haemorrhage, with no history of instrumental delivery or facial trauma. (
  • Trauma, eg ear trauma or peripheral facial trauma. (
  • Trauma and head injury are the common causes of damage to the facial nerve. (
  • The facial nerve travels with the hearing nerve (the eighth cranial nerve) as it travels in and around the structures of the middle ear. (
  • This leaves the facial nerve exposed to the cavity and therefore to disease processes affecting the middle ear. (
  • In addition, severe infections of the middle ear have also been associated with facial nerve damage. (
  • Inflammatory and infectious causes of facial paralysis can occur. (
  • Inflammatory causes of facial paralysis include sarcoidosis. (
  • Facial paralysis occurs when there is loss of facial movement, and there are many causes of facial paralysis (more than 100! (
  • The first segment of the facial nerve, the intracranial (cisternal) segment, travels within the skull and divides into several branches. (
  • Paralysis of the facial nerve is a cause of significant functional and aesthetic compromise. (
  • Our facial nerve team is a multidisciplinary collaboration of neurologists, head and neck surgeons, neurosurgeons and plastic and reconstructive surgeons. (
  • Our team of experts includes facial plastic and reconstructive surgeons, head and neck surgeons, ophthalmologists, neurologists, physical therapists and social workers. (
  • MR should be a sensitive study for the evaluation of intratemporal facial nerve disease. (
  • Patients with facial paralysis, especially younger ones, may experience tremendous psychosocial distress about their condition. (
  • Patients with facial nerve contrast enhancement have a slower recovery than those without enhancement (19.3 versus 9.5 weeks). (
  • The greater petrosal nerve arises at the superior salivatory nucleus of the pons and provides parasympathetic innervation to several glands, including the nasal glands, the palatine glands, the lacrimal gland, and the pharyngeal gland. (
  • Patients have to be ready to work with physical therapy to retrain their brains to use the new nerve innervation. (
  • The facial muscles are innervated peripherally (infranuclear innervation) by the ipsilateral 7th cranial nerve and centrally (supranuclear innervation) by the contralateral cerebral cortex. (
  • Textbooks go to great pains to explain that the frontal muscles receive bilateral innervation, and that frowning is therefore still possible in "central facial paralysis. (
  • Also, this nerve innervates facial muscles, controlling how to contract and produce facial expressions. (
  • Facial nerve damage can affect your ability to form expressions, such as smiling. (
  • One of the most common signs of a damaged facial nerve is sagging on one side of the face--creating a lopsided appearance--and difficulty forming facial expressions, such as smiling, says the Patient UK website. (
  • The nerves these control include: facial expressions, also eye-blinking, as well as the closing and opening of eyelids. (
  • Facial expressions provide unique insight into a person's emotions and are important for communication. (
  • Also called cranial nerve VII, this nerve controls the muscles used for facial expressions, and branches to the tongue also play a role in the sense of taste. (
  • Would you like to restore the ability to respond emotionally with facial expressions? (
  • The facial nerve controls various facial expressions and the sensation of taste to some extent. (
