From Wikipedia, the free encyclopedia Bell's palsy is a type of facial paralysis that results in a temporary inability to control the facial muscles on the affected side of the face. Symptoms can vary from mild to severe The facial nerve (the labyrinthine segment) is the seventh cranial nerve, or simply CN VII. It emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue
Bilateral course of facial nerve. Note that the forehead muscles receive innervation from both hemispheres of the brain, which is why there is forehead sparing for stroke but not Bell's palsy (or other peripheral facial nerve injury). Key to distinguish between central and peripheral facial nerve palsy Facial palsy is due to the damage in the facial nerve that supplies the muscles of the face. It can be categorized into two based on the location of casual pathology: Central facial palsy- due to damage above the facial nucleus Peripheral facial palsy-due to damage at or below the facial nucleu Bell's palsy, also known as acute peripheral facial palsy of unknown cause, can occur at any age. The exact cause is unknown. It's believed to be the result of swelling and inflammation of the nerve that controls the muscles on one side of your face. Or it might be a reaction that occurs after a viral infection Facial paralysis is a loss of facial movement due to nerve damage. Your facial muscles may appear to droop or become weak. It can happen on one or both sides of the face. Common causes of facial.. Summary. Facial (nerve) palsy is a neurological condition in which function of the facial nerve (cranial nerve VII) is partially or completely lost.It is often idiopathic but in some cases, specific causes such as trauma, infections, or metabolic disorders can be identified. Two major types are distinguished: central facial palsy (lesion occurs between cortex and nuclei in the brainstem) and.
The facial nerve is one of the key cranial nerves with a complex and broad range of functions.. Although at first glance it is the motor nerve of facial expression which begins as a trunk and emerges from the parotid gland as five branches (see facial nerve branches mnemonic), it has taste and parasympathetic fibers that relay in a complex manner..

Facial paresis is reduced movement of the muscles of facial expression and indicates milder nucleus or nerve involvement. The nucleus of the facial nerve is located in the rostral medulla oblongata of the brain stem. The facial nerve, cranial nerve VII.
Facial nerve paralysis is a common problem that involves the paralysis of any structures innervated by the facial nerve. The pathway of the facial nerve is long and relatively convoluted, so there are a number of causes that may result in facial nerve paralysis. The most common is Bell's palsy, a disease of unknown cause that may only be diagnosed by exclusion of identifiable serious. Editor-In-Chief: C. Michael Gibson, M.S., M.D. Causes Common Causes Bell's palsy. Bell's palsy is the most common cause of acute facial nerve paralysis (>80%). Previously considered idiopathic, it has been recently linked to herpes zosterof the facial nerve (rarely Lyme disease).. Bell's palsy is an exclusion diagnosis. Some factors that tend to rule out Bell's palsy include Introduction. Isolated facial nerve palsy usually manifests as Bell's palsy, which is commonly described as an acute peripheral facial palsy of unknown cause .Bell's palsy typically presents with a sudden onset (usually over a period of hours) of unilateral facial paralysis that typically resolves over a period of six months [1,2].Lacunar infarct involving the lower pons is a rare cause of. Introduction. A facial palsy is weakness or paralysis of the muscles of the face. Whilst the majority of cases are idiopathic, termed Bell's Palsy, there are a wide range of potential causes of a facial palsy.. Bell's palsy is a diagnosis of exclusion and hence all possible causes have to be excluded first prior to diagnosing Bell's palsy. The majority of this article will discuss Bell.
Bell's palsy. Bell's palsy is the most commonly diagnosed condition related to facial nerve dysfunction. It is a non-life threatening condition, thought to be caused by a viral infection that leads to damage and inflammation of the facial nerve According to Tiemstra and Khatkhate (2007), Bell's palsy is a peripheral palsy of the facial nerve that results in muscle weakness on one side of the face. Affected patients develop unilateral facial paralysis over one to three days with forehead involvement and no other neurologic abnormalities

The most common cause of acute onset unilateral peripheral facial weakness is Bell's palsy. The incidence of Bell's palsy is 20-30 cases for 100,000 and accounts for 60-70% of all cases of unilateral peripheral facial palsy. Either sex is affected equally and may occur at any age, the median age is 40 years To fully understand the difference between Bell's palsy (lower motor neuron facial palsy), and the facial weakness caused by ischaemic stroke (upper motor neuron facial palsy), a sound understanding of the anatomy of the facial nerve (CN VII) is required. The facial nerve is the seventh of the cranial nerves facial nerve palsy: Acute peripheral paralysis of the face due to a herpes simplex immune-mediated condition, often characterised by severe pain arising in the trigeminal nerve, the chief sensory nerve of the face, which arises in cranial nerve VII. Clinical findings Abrupt onset, drooping mouth, unblinking eye, twisted nose, uneven smile,. General Discussion. Bell's palsy is a non-progressive neurological disorder of one of the facial nerves (7th cranial nerve). This disorder is characterized by the sudden onset of facial paralysis that may be preceded by a slight fever, pain behind the ear on the affected side, a stiff neck, and weakness and/or stiffness on one side of the face
quantify facial nerve functional recovery after surgery that puts the facial nerve at risk, but has been used to assess recovery after trauma to the facial nerve, or Bell's palsy.19 It was not designed to assess initial facial nerve paresis or paralysis of Bell's palsy. The House-Brackmann facial nerve grading system is described in Table 1 Bell's Palsy, or Bell Palsy, is facial paralysis which is caused by dysfunction of Cranial Nerve VII, the Facial Nerve. Also known as Idiopathic Facial Palsy. It is named after Sir Charles Bell [1774 to 1842], who was a Scottish surgeon, neurologist and anatomist. It results in inability or reduced ability, to move the muscles on the affected. .) Should be distinguished from these differentials (usually based on speed of onset and lack of other signs): a. Otitis media b. Neoplasia of the facial nerve c. Brainstem disease Best treatment is controversial but may consist of tear supplementation, thyroid supplementatio
Within the facial canal Greater petrosal nerve Nerve to stapedius : arises opposite the pyramid of middle ear and supplies the stapedius muscle. The muscle damps excessive vibrations of the stapes caused by high - pitched sounds. In paralysis of the muscle even normal sounds appear too loud and is known as hyperacusis. 14 The exact pathophysiology of Bell's palsy is not known. Bell's palsy occurs due to failure to function in a normal manner of the facial nerve (VII cranial nerve). The malfunction of the facial nerve caused involuntary spasm in the facial muscles which called facial palsy. Bell's palsy causes the lower motor neuron type paralysis Bell's palsy is facial nerve paralysis of unknown cause. Left untreated, 70-75% of patients make a full recovery. Early treatment with prednisolone increases the chance of complete recovery of facial function to 82%. Eleven people need to be treated for one extra complete recovery at six months. There may be benefit in adding an antiviral. Medications. Commonly used medications to treat Bell's palsy include: Corticosteroids, such as prednisone, are powerful anti-inflammatory agents. If they can reduce the swelling of the facial nerve, it will fit more comfortably within the bony corridor that surrounds it Also know as Ramsay Hunt syndrome. Acute peripheral facial neuropathy associated with erythematous vesicular rash of the skin of the ear canal, auricle, or mucous membrane of the oropharynx. Associated facial paralysis usually involving CN VII but may involve CN VIII. geniculate ganglion: movements of the facial muscles, sensation of parts of.
Eleven patients with ocular-oral synkinesis after facial paralysis underwent the cross-facial nerve grafting with facial nerve transposition at a tertiary academic hospital between 2003 and 2009. The patient selection for the study was based on the degree of disfigurement and facial function parameter rating using the Toronto Facial Grading System Once a central cause for facial palsy has been excluded, perform a focused examination of the ears, mastoid region, oral cavity, eyes, scalp, and parotid glands to look for the specific signs in the table.

Bell's palsy (facial paralysis) is due to unilateral inflammation of the seventh cranial nerve, which results in weakness or paralysis of the facial muscles on the affected side (Fig. 64-8). The cause is unknown, although possible causes may include vascular ischemia, viral disease (herpes simplex, herpes zoster), autoimmune disease, or a. The facial nerve detects sensation from the small area behind the ear described as the auricle. The sensory information from this area is transmitted through the facial nerve to the brainstem, then to the thalamus in the brain, and eventually to the cerebral cortex, where the brain can integrate and make sense of the sensation
The facial nerve is composed of approximately 10,000 neurons, 7,000 of which are myelinated and innervate the nerves of facial expression. Three thousand of the nerve fibers are somatosensory and secretomotor and make up the nervus intermedius.

Below the form you can find more information on the clinical assessment of facial nerve paralysis. 1 About 35 per 100,000 people get Bell's palsy in the U.S. each year, according to the National Organization for Rare Disorders, and about 40,000 Americans are diagnosed annually There are many conditions that produce isolated facial nerve palsy identical to Bell's palsy and up to 30% of patients with acute facial nerve paralysis will not have Bell's palsy (Holland, 2006, Holland, 2011).These may be structural lesions from the parotid gland or the ear, which produce facial nerve compression, as well as various infectious and inflammatory conditions Bell's palsy is characterised by an acute onset of unilateral, lower motor neuron weakness of the facial nerve in the absence of an identifiable cause. 1 The annual incidence is estimated to be 11-40 per 100,000, with a lifetime risk of one in 60. On average, general practitioners (GPs) encounter one acute case every two years. 2 Most cases of Bell's palsy resolve spontaneously
Isolated facial nerve palsy usually manifests as Bell's palsy. Lacunar infarct involving the lower pons is a rare cause of solitary infranuclear facial paralysis. The present unusual case is one in which the patient appeared to have Bell's palsy but turned out to have a pontine infarct. A 47-year-old Asian Indian man with a medical history of hypertension presented to our institution with. Paralysis often includes loss of feeling in the affected area. Paralysis may be localized, or generalized, or it may follow a certain pattern. For example, localized paralysis occurs in Bell's palsy where one side of the face may be paralysed due to inflammation of the facial nerve on that side
Bell's palsy is a form of facial paralysis resulting from a dysfunction of the cranial nerve VII (the facial nerve) causing an inability to control facial muscles on the affected side.

Tarsal tunnel syndrome - Tibial nerve; Facial (note: although these are conditions which affect only a single nerve, they are less frequently called mononeuropathies than the conditions above) Oculomotor nerve palsy - Oculomotor nerve (III) Fourth nerve palsy - Trochlear nerve (IV) Sixth nerve palsy - Abducens nerve (VI) Bell's palsy - Facial. Idiopathic facial paresis is also thought to be the result of viral reactivation along the motor division of the facial nerve (Adour et al., 1975).Viral etiologies (HSV, VZV, HHV-6) have been identified and are in large part identical to those seen in herpes labialis (Burgess et al., 1994, Zandian et al., 2014, Turriziani et al., 2014).The pathogenesis of facial paralysis involves reactivation. Bell's Palsy is a peripheral nerve effect whereas a ischemic stroke is a central process. As shown in the diagram, the forehead receives motor innervation from both hemispheres of the cerebral cortex. A stroke that compromised motor innervation of the face would therefore only result in paralysis of the lower half of the face - the forehead. The ICD code G510 is used to code Bell's palsy. Bell's palsy is a form of facial paralysis resulting from a dysfunction of the cranial nerve VII (the facial nerve) causing an inability to control facial muscles on the affected side. Often the eye in the affected side cannot be closed The taste sensations for the front two-thirds of the tongue are sent to the brain via the seventh cranial nerve. In Bell's palsy, this nerve becomes compressed due to swelling and inflammation that is a part of the body's reaction to an infectious disease process
