What Is Bell's Palsy?
The longest canal in the bone that moves the muscles of the body the nerves facial nerve the nerve (the facial nerve), stroke is one of the most common of the common borders. This paralysis is approximately 90% of the diseases of the bones of the border through the canal of the ear, depending on circumstances. The most common cause of facial paralysis of unknown cause and is usually self-limiting disease, which is Bell's palsy, although the middle ear pathologies such as infections or tumors of bone destruction engaged in it should be kept in mind that may cause paralysis. This region is the treatment of diseases of ear, nose and throat otolaryngologist necessarily due to enter the field of Medicine by patients with Bell's palsy should be assessed.
Nerve fibers from the facial nerve from the brain to the upper half of the face with the same face part in a portion of the brain stem on the way to the half half face against caprazlasara goes. However, the lower half of the nerve fibers in the brain that are running all the face related caprazlasara stimulate the muscles of the face in the opposite half after leaving the centre. Therefore, on one side of the face occurring in the brain in the pathology of the muscles in the lower half on the opposite side is affected by the event in the case where the region of the upper face to receive alerts from the brain intact with the other side is not affected.
This type of paralysis that affects the rest of the face below is a review of “plant type facial palsy” as pathology in the brain stem and the lower region of the face due to paralysis that affects a half exactly and the “peripheral type facial palsy, are called. Although this finding is important in the differential diagnosis of peripheral nerve stimulation of the protected status of the upper face of Medicine in pathology may be it should be noted that in half.
After exiting the facial nerve from the brain, it penetrates into the bone of the ear with the hearing and balance nerves by watching together. The inner ear canal (the internal acoustic canal) in pathology in this region which is called facial paralysis may be accompanied by complaints of hearing and balance.
As you move through the channels within the bone of the facial nerve ear stimulate the tear gland, 2/3 of the stirrup bone in the middle ear and the sense of taste stimulate the muscles in the front part of the language area, the salivary glands under the jaw that are running gives branches. After exiting nerve from the bone of the ear, the ear and extends toward the front of six salivary glands (Parotid gland) that stimulate the facial muscles on the face by passing it through the branch is divided into.
The secretion of tears in facial paralysis, tongue and sense of taste of the stirrup muscle disease occurs whether or not the function of the region/findings to help in the determination of the level.
Facial Paralysis Causes
Although there are many causes of facial palsy, the most common ones rapidly developing acute and chronic - can be divided into two groups as slowly progressive.
The Fastest Growing Acute Strokes:
- Nerve inflammations
- Bell's palsy (facial paralysis of unknown origin)
- Herpes zoster virus infection
- Guillain-Barre syndrome
- Auto immune facial palsy
- Lyme disease
- AIDS
- Kawasaki disease
Trauma
- Fractures of the bones of the ear
- Trauma pressure
- Birth trauma
Middle ear infections
- Acute bacterial infections
- Chronic bacterial infections
- Degeneration of bone within the bone tissue in chronic otitis media (serous) formation of
Sarcoidosis
- Neurologic diseases of the nervous system
Chronic Slowly Progressive Paralysis:
- Malignant tumors
- Salivary glands in the cheek (the parotid tumors
- Jumping from other places (metastatic) tumor
- Benign tumors (glomus tumor, schwannoma)
- Chronic middle ear fluid (serous)
Facial Paralysis Treatment
The treatment will vary according to the factors that cause facial paralysis. The purpose of the treatment the normal facial appearance and facial symmetry emotional movements during voluntary movement of the mouth, nose and around the eyes is the provision of the functions of Nov.
Bell's Palsy: Trauma, tumor, infection, acute facial paralysis called Bell's palsy is an obvious cause such as undetectable. The exact cause is not known, but upon viral infection, an immune mechanism are considered to occur as attached. Self-limiting and usually resolves spontaneously Bell's paralysis is a condition in which progressive are not. Patients, 80-90% of patients completely healed paralysis in a loss of full mobility will be occurred if this ratio in -100 is e. However, early tests of the paralysis is complete and in 90% loss of nerve fibers in patients with complete recovery rate of 50 percent.
In the treatment of patients within the first 3 days after Stroke, Bell's palsy is a situation that will create a barrier to the patient's decision is issued through the mouth or through a vein after appropriate treatment is introduced gradually reducing the dose of cortisone by 2-3 days on average, continue for 15 days. In order to prevent adverse effects on the gastrointestinal system, the stomach of cortisone protective treatment should be given. Factors due to the possibility of the virus by mouth for the treatment of anti-viral drugs are added. Complete loss of facial nerve function during the recovery period to prevent thinning of the muscles of the face situations in a hot applied, applies to facial exercises and massage. The eyes remain open due to the protective treatment for prevention of complications such as keratitis caused by drying apply.
The use of cortisone in cases where it is inconvenient (e.g., uncontrolled diabetes, pregnancy, etc) capillary to increase circulation treatment can be given. Improvement in the monitoring of the patient at the end of three weeks if you have supportive treatment are continuing to unmonitored patients clinical improvement electrically Nov stimulation test (EMG) is performed. Also are continuing signs of improvement with medical treatment in patients with EMG monitoring, warning and recovery for the patients with total loss the findings of magnetic resonance examination is performed.
This examination of any pathology in patients with appropriate surgical technique practiced surgery for liberalisation in the limit of the channel. As the duration of paralysis decreases the quality of recovery. The face of the functions of the surgical intervention to be made as soon as possible in the most ideal way is considered to be the most important factor in winning again. Therefore, in patients with facial paralysis has a significant impact in the improvement of early diagnosis and appropriate treatment.
Trauma: For the frequency ranks second in the causes of facial palsy. Ear bone fractures, surgical trauma (surgical trauma injuries that inevitably occur during surgery or may be involuntary.
Fractures of the bones of the ear: Paralysis of the facial nerve after trauma are considered to be in a cut or a bruise. In this case, the pathology within the shortest possible time and with the appropriate surgical technique should be operated according to the state of repair and, if necessary, the removal of the pressure on the nerves should be performed. Trauma of the nerve within the canal that begins after a period of paralysis can occur due to swelling or bleeding. In this case, is like Bell's palsy treatment.In the case that does not respond to treatment, surgical comes to the fore.
Acute and chronic middle ear infections: In the treatment of acute otitis media and facial nerve paralysis seen during intravenous antibiotics should be initiated by opening a hole on the ear fluid in the middle ear discharge must be provided. In addition, the cortisone treatment can be applied.
Chronic otitis media otitis media is an inflammation of bone dissolving paralysis associated with greater chances of finding a growing audience. Depending on the mechanism of nerve compression or inflammation involved on the regional stroke occurs. In these cases, urgent surgical intervention is required.
Herpes Zoster Otikus: (Ramsey Hunt syndrome) occurs depending on the varicella zoster virus. Often the external ear on the scalp, face, vesicular lesions similar to cold sores on the lips or in the lobby. Different from the findings of the nerve and Bell's palsy is caused by complete degeneration usually be more serious. This disease is more common in people with immune deficiency mainly in cellular medicine. Values between -22 and low rate of complete recovery are given. Treatment of virus-specific anti-viral drugs should be used. Bell's palsy treatment protocol as in the other.
Pathology of the bones of the ear: Usually from trauma or a salivary gland in the cheek (the parotid original) depending on the tumor consists of. Treatment depending on the cause, there are different surgical methods.
