    Facial nerve paralysis is paralysis of half of the face. Most people recover spontaneously within one month of injury, but in 30% of cases, patients show a late or incomplete recovery.

    What is facial nerve palsy?

    Facial nerve paralysis

    Facial nerve palsy is paralysis of one half of the face and may be associated with mild pain, numbness, increased sensitivity to sound, and a change in taste.

    Hemifacial paralysis is idiopathic, but a proportion of cases may be caused by the herpes virus in the geniculate ganglion of the facial nerve.

    Bell's palsy is more common in people aged 15 to 40 years.

    Most people recover spontaneously within one month of nerve injury, but in 30% of cases people have a late or incomplete recovery.

    It is a condition in which the muscles on one side of the face become weak or temporarily paralyzed, affecting only one side of the face, causing it to droop or stiffen on that side.

    The symptoms of seventh nerve palsy are similar to stroke in that there is numbness with the difference that a stroke causes numbness of the muscles of other parts of the body in addition to the muscles of the face.

    In order to obtain an accurate diagnosis of the disease, it is necessary to identify the most important symptoms.

    Symptoms of seventh facial nerve paralysis

    • The most obvious sign is drooping on one side of the face, difficulty closing the eye on the affected side, and difficulty smiling and making other facial expressions.
    • In rare cases, nerve paralysis can occur on both sides of the face.

    In addition to the difficulty in moving the muscles of the face, some other symptoms that appear in sufferers can be noted:

    • dry eyes and mouth
    • Pain in the jaws or behind the ear, which often occurs before symptoms appear (1 to 4 days before they appear)
    • a headache
    • Weakness in the sense of taste
    • ringing in the ears
    • Increasing sensitivity to sounds where the sounds sound much louder than usual in the days before symptoms appear
    • Difficulty speaking, eating and drinking

    Causes of facial nerve paralysis

    The cause of facial nerve paralysis is still not fully defined, but it is believed that the cause is damage or inflammation of the facial nerve, which leads to swelling and enlargement in it.

    Where the facial nerve passes through a narrow bony area inside the skull, and as a result of its enlargement, it is compressed within the surrounding solid bone, causing a defect in the work of this nerve.

    Viral infections may play a role in facial nerve paralysis, as the herpes virus 1 (human herpes virus 1) is responsible in a large number of cases, and there are some other viruses related to facial nerve paralysis:

    • German measles Rubella
    • Mumps virus
    • Influenza B
    • Chickenpox and shingles Herpes zoster
    • Epstein-Barr mononucleosis
    • Cytomegalovirus
    • virus hand, foot and mouth disease Coxsackievirus

    Predisposing factors for facial nerve paralysis

    There are several factors that increase the likelihood of developing facial nerve paralysis:

    • pregnancy; The risk of infection may increase if the female is pregnant, especially during the last three months of pregnancy or in the first week after childbirth
    • diabetic; where showed Studies Link between diabetes and facial nerve paralysis
    • Some autoimmune diseases
    • cold sores
    • Hypertension

    Diagnosis of facial nerve palsy

    There is no specific laboratory test for diagnosing facial nerve paralysis, but rather it is discovered through what is called an exclusionary diagnosis, which means that doctors do not diagnose facial nerve palsy until all other possibilities have been ruled out.

    A full physical examination is usually done, and a careful examination of the facial muscles is done by trying all facial expressions such as smiling.

    Your doctor may order an EMG to measure the electrical activity of the muscle.

    The doctor may also order an X-ray of the skull or an MRI to make sure there is no tumor or fracture in the bone pressing on the nerve.

    Facial nerve paralysis treatment

    In some people, we may notice a longer recovery period. In some rare cases, symptoms are permanent, but usually improvement occurs within the three weeks following the onset of symptoms.

    • Most people with this condition recover spontaneously without receiving treatment, but there are some treatments that may help recover faster, such as corticosteroids that help reduce swelling and increase the likelihood of nerve function returning to normal and thus reducing the duration of symptoms of facial nerve paralysis, with Note that they work best if taken within 72 hours of symptoms starting.
    • Antiviral therapy may be needed if symptoms are caused by the herpes virus 1 (human herpes virus 1) or shingles (chickenpox virus).
    • If paralysis impairs closing of the eye, the affected eye should be protected using sterile eye drops to keep it moist.
    • Facial massage movements must be observed.
    • Any surgical intervention to treat facial nerve paralysis is not recommended unless symptoms persist for a long time or when complications occur.

    Complications

    • Facial nerve damage
    • Permanent weakness of facial muscles
    • Involuntary muscle contraction
    • Partial or complete blindness of an eye that has not closed due to excessive dryness and scratching of the cornea

    The difference between facial nerve paralysis and stroke

    It is important to know the difference between the symptoms of facial nerve paralysis and stroke on the face, as both are the most common causes of facial muscle weakness.

    While seventh nerve palsy is not an emergency, a stroke needs emergency treatment in a well-equipped hospital.

    It is therefore important to prompt medical evaluation of any sudden weakness of the facial muscles to rule out it being part of the symptoms of a stroke, especially if it is accompanied by an inability to raise the arm or difficulty speaking.

    In the case of facial nerve paralysis, we notice the disappearance of the forehead wrinkles on the affected side when raising the eyebrows.
    In the case of a stroke, the forehead wrinkles are not lost on the affected side of the face, and the person is able to raise his eyebrows in the affected area because of the double nerve feeding coming from the brain to these areas.
