Bell’S Palsy

(Bell’s palsy)

A paralysis of the facial nerve (VII. Cranial nerve) is often idiopathic (and was formerly known as Bell’s palsy). The idiopathic facial palsy is a sudden onset of unilateral peripheral facial nerve paralysis. Symptoms of Bell’s palsy is a unilateral facial paralysis of the upper and lower face. Tests (eg. As Röntgenthorax-, serum ACE levels) may be performed to diagnose treatable causes. The treatment may wetting of the eye, which include the intermittent use of an eye patch and, in idiopathic facial paralysis corticosteroids.

Earlier it was the etiology Bell palsy held for a idiopathic facial palsy (peripheral VII. Cranial nerve). However, the facial palsy is now regarded as a clinical syndrome with its own differential diagnosis, and the term “Bell Palsy” is not always used synonymously with idiopathic facial paralysis. (Editor’s note:.. Synonymously in German in accordance with the guidelines of the Society for Neuroscience dt) About half of the cases of facial paralysis are idiopathic. The mechanism of idiopathic facial paralysis is probably in the swelling of the facial nerve due to an immune or viral disease. Current evidence suggests that infection with the herpes simplex virus is the most common cause and that herpes zoster may be the second most common viral cause. Other viral causes are Coxsackie virus, cytomegalovirus, adenovirus, and Epstein-Barr, mumps, rubella and influenza B virus. The swollen nerve is compressed to the maximum while passing through the section of Fazialskanals in the labyrinth, resulting in ischemia and paralysis. Various other diseases (eg. As Lyme disease, sarcoidosis) can cause facial paralysis. Pathophysiology The facial muscles are innervated by the contralateral cerebral cortex peripherally (infranuclear innervation) from the ipsilateral seventh cranial nerve and central (supranuclear innervation). the central innervation tends to occur in the upper half of the face to be bilaterally (z. B. frontal muscles) and one side in the lower half of the face. As a result, both the central and peripheral lesions tend to paralyze the bottom. However, peripheral lesions (facial palsy) usually tend to be related to the upper half of the face do it as a central lesions (eg., stroke). Symptoms and signs In idiopathic facial paralysis is often the facial paralysis ahead of a pain behind the ear. The paralysis, often with a complete Plegie, develops within hours and reaches its maximum usually within 48-72 hours. Patients may report numbness or a feeling of heaviness in the face. The data page is flat and without expression, the ability to frowning, grimacing, or blinking is limited or absent. In severe cases, the eyelid is extended and the eye can not be closed, which often irritates the conjunctiva and cornea dries out. Bell’s palsy DR P.
