G., the varicella-zoster virus 12 and EpsteinBarr viruses, both of the herpes family. Reactivation of an existing (dormant) viral infection has been suggested 13 as a cause of acute bell's palsy. Studies suggest that this new activation could be preceded by trauma, environmental factors, and metabolic or emotional disorders, thus suggesting that a host of different conditions may trigger reactivation. 14 Familial inheritance has been found in 414 of cases. 15 Bell's palsy is three times more likely to occur in pregnant women than non-pregnant women. 16 It is also considered to be four times more likely to occur in diabetics than the general population. 17 Pathophysiology edit Anatomy of the face. Bell's palsy occurs due to a malfunction of the facial nerve (vii cranial nerve which controls the muscles of the face.
8 9 The facial nerve controls a number of functions, such as blinking and manicure closing the eyes, smiling, frowning, lacrimation, salivation, flaring nostrils and raising eyebrows. It also carries taste sensations from the anterior two-thirds of the tongue, via the chorda tympani nerve (a branch of the facial nerve). Because of this, people with Bell's palsy may present with loss of taste sensation in the anterior 2/3 of the tongue on the affected side. 10 Although the facial nerve innervates the stapedial muscles of the middle ear (via the tympanic branch sound sensitivity and dysacusis are hardly ever clinically evident. 10 Although defined as a mononeuritis (involving only one nerve people diagnosed with Bells palsy may have "myriad neurological symptoms" including "facial tingling, moderate or severe headache/neck pain, memory problems, balance problems, ipsilateral limb paresthesias, ipsilateral limb weakness, and a sense of clumsiness" that are. 11 Facial nerve : the facial nerve's nuclei are in the brainstem (they are represented in the diagram as a θ). Orange: nerves coming from the left hemisphere of the brain. Yellow: nerves coming from the right hemisphere of the brain. Note that the forehead muscles receive innervation from both hemispheres of the brain (represented in yellow and orange). Some viruses are thought to establish a persistent (or latent ) infection without symptoms,.
nerve paralysis (70). 2 5 It occurs in 1 to 4 per 10,000 people per year. 2 About.5 of people are affected at some point in their life. 6 It most commonly occurs in people between ages 15 and. 1 Males and females are affected equally. 1 It is named after Scottish surgeon Charles Bell (17741842 who first described the connection of the facial nerve to the condition. 1 Contents Signs and symptoms edit bell's palsy is characterized by a one-sided facial droop that comes on within 72 hours. 7 In rare cases ( 1 it can occur on both sides resulting in total facial paralysis.

1, many believe that this is due to a viral infection that results in swelling. 1, diagnosis is based on a person's appearance and ruling out other possible causes. 1, other conditions that can cause facial weakness include brain tumor, stroke, ramsay hunt syndrome, myasthenia gravis, and, lyme disease. 2, the condition normally gets better by itself with most achieving normal or near-normal function. Corticosteroids have been found to improve outcomes, while antiviral medications may be of a small additional benefit. 4 The eye should be protected from drying up with the use weleda of eye drops rosacea or an eyepatch. 1 Surgery is generally not recommended.

Patients often complain of a feeling of numbness from the paralysis, but facial sensation is preserved. Patients with Bell's palsy usually progress from onset of symptoms to maximal weakness within three days and almost always within one week. A more insidious onset or progression over more than two weeks should prompt reconsideration of the diagnosis. Left untreated, 85 percent of patients will show at least partial recovery within three weeks of onset. Etiology and Differential diagnosis, jump to section, bell's palsy is believed to be caused by inflammation of the facial nerve at the geniculate ganglion, which leads to compression and possible ischemia and demyelination. This ganglion lies in the facial canal at the junction of the labyrinthine and tympanic segments, where the nerve curves sharply toward the stylomastoid foramen. Classically, bell's palsy has been defined as idiopathic, and the cause of the inflammatory process in the facial nerve remains uncertain. Recently, attention has focused on infection with herpes simplex virus type 1 (hsv-1) as a possible cause because research has found elevated hsv-1 titers in affected patients.
B 15 17, patients with complete paralysis who do not improve in two weeks on medication should be referred to an otolaryngologist for evaluation for other causes of facial nerve palsy. C 19, 20, patients should be monitored for eye irritation and be prescribed eye lubrication. Patients with corneal abrasions should be referred to an ophthalmologist. C 1, 23, a consistent, good-quality patient-oriented evidence; b inconsistent or limited-quality patient-oriented evidence; c consensus, disease-oriented evidence, usual practice, expert opinion, or case series. For information about the sort evidence rating system, see page 922. Anatomy of the facial nerve. Clinical Presentation, jump to section, patients with Bell's palsy typically complain of weakness or complete paralysis of all the muscles on one side of the face.
The facial creases and nasolabial fold disappear, the forehead unfurrows, and the corner of the mouth droops. The eyelids will not close and the lower lid sags; on attempted closure, the eye rolls upward (Bell's phenomenon). Eye irritation often results from lack of lubrication and constant exposure. Tear production decreases; however, the eye may appear engels to tear excessively because of loss of lid control, which allows tears to spill freely from the eye. Food and saliva can pool in the affected side of the mouth and may spill out from the corner.
Bell's Palsy: causes, symptoms and Treatment in Children
The facial nerve also contains parasympathetic fibers to the lacrimal and salivary glands, as light well as limited sensory fibers supplying taste to the anterior two thirds of the tongue (. Bell's palsy is vitamin named after Sir Charles Bell (17741842 who first described the syndrome along with the anatomy and function of the facial nerve. The annual incidence of Bell's palsy is 15 to 30 per 100,000 persons, with equal numbers of men and women affected. There is no predilection for either side of the face. Bell's palsy has been described in patients of all ages, with peak incidence noted in the 40s. It occurs more commonly in patients with diabetes and in pregnant women. Patients who have had one episode of Bell's palsy have an 8 percent risk of recurrence. 1, 2, sORT: key recommendations for practice, clinical recommendationEvidence ratingReferences. Patients with Bell's palsy should be treated within three days of the onset of symptoms with a seven-day course of oral acyclovir (zovirax) or valacyclovir (Valtrex plus a tapering course of oral prednisone.

Bell's palsy is more common in patients with diabetes, and although it can affect persons of healthy any age, incidence peaks in the 40s. Bell's palsy has been traditionally defined as idiopathic; however, one possible etiology is infection with herpes simplex virus type. Laboratory evaluation, when indicated by history or risk factors, may include testing for diabetes mellitus and Lyme disease. A common short-term complication of Bell's palsy is incomplete eyelid closure with resultant dry eye. A less common long-term complication is permanent facial weakness with muscle contractures. Approximately 70 to 80 percent of patients will recover spontaneously; however, treatment with a seven-day course of acyclovir or valacyclovir and a tapering course of prednisone, initiated within three days of the onset of symptoms, is recommended to reduce the time to full recovery and. Bell's palsy is an idiopathic, acute peripheral-nerve palsy involving the facial nerve, which supplies all the muscles of facial expression.
