Bell’s Palsy – Clinical Features and Therapeutic Options in Managing Peripheral Facial Palsy

13 Jan 2025

Our face can reveal valuable clues about our health, especially in the neurological sphere. Why? Because certain neurological conditions have facial paralysis as a characteristic symptom. This can manifest in several ways, but an essential aspect is that it can have diverse etiologies.

Facial paralysis can indicate an underlying pathology or be a standalone condition. In this context, Bell’s palsy appears, a condition caused by inflammation of a cranial nerve. Also known as peripheral facial paralysis (PFP), it is often mistaken for stroke symptoms, which can cause significant concern.

What exactly is Bell’s palsy? It is a condition that causes weakness or immobility of the muscles on one side of the face. Below, we will explore when this disease occurs, its symptoms, and also the steps towards full recovery, when the appropriate therapeutic protocol is followed.

What Is Bell’s Palsy and What Are the Clinical Features of This Condition?

What is Bell’s palsy? This type of facial paresis is a neurological condition with several specific characteristics. Although the term “paralysis” can often induce anxiety, being frequently associated with stroke, this perception does not apply in the case of Bell’s palsy. Known as *peripheral facial paralysis (PFP)*, this neurological condition manifests suddenly, affecting the facial nerve, respectively the 7th cranial nerve.

The main sign of Bell’s palsy is muscle weakness on one half of the face.

But this is not the only aspect to consider; it is essential to pay attention to other symptoms as well. A significant feature of the disease is that, in rare cases, it can be hereditary. Therefore, by carefully monitoring our neurological health, we can prevent the onset of this condition.

Treating Bell’s Palsy with Natural Methods

How can we take care of the health of our nervous system? An essential factor is adequate vitamin B intake, which plays a crucial role in supporting neurological functions. Through the supplement Premium Aronia Vitamin B-Complex 500ml we can obtain all its benefits, including supporting neurological function. More precisely, out of this complex, vitamins B3, B5, and B6 play the most important role in the proper functioning of the nervous system.

The Premium Aronia formula is enriched with vitamin C, recognized as one of the most effective natural antioxidants, thus contributing to combating oxidative stress. With the addition of aronia and apple juice, this adjuvant has a pleasant taste, making it easy to administer even to children. Why is it also important for the little ones? Because they can also be affected by Bell’s palsy. Therefore, using this supplement allows us to do everything in our power to prevent the onset of the disease.

Risk Groups Susceptible to Bell’s Palsy

Who does Bell’s palsy affect? This condition can affect people of all age groups, including children, as it is not the result of a stroke, nor an ischemic accident. However, Bell’s palsy most commonly affects individuals between the ages of 15 and 60. The onset of symptoms is sudden, occurring 24-48 hours after triggering.

Encouraging news regarding Bell’s palsy is the high recovery rate. Both adults and children can experience significant improvement within a few weeks. However, there are situations where recovery is not complete, which can lead to long-term complications.

In the case of children, Bell’s palsy can also be caused by trauma to the face or head. These complications can cause permanent damage to the facial nerve, as well as the bony structures of the skull. However, in children, the most common form of the disease is associated with viral infections.

How Bell’s Palsy Manifests in Adults and Children

Here are some of its physical signs:

facial asymmetry on the side affected by idiopathic peripheral facial paralysis;
flattening of facial folds on that side;
drooping of the eyebrow;
lowering and narrowing of the mouth opening;
flattening of the nose on the side where paralysis has occurred.

Although these physical characteristics can be included in the disease’s symptomatology, it is important to mention that Bell’s palsy has other manifestations. Generally, these are similar in both adults and children. This condition is considered idiopathic, with the main cause often being unclear.

Bell’s Palsy – Triggering Causes and Risk Factors

It is important to know that Bell’s palsy has various causes, each contributing differently to the onset of this condition. According to the latest medical research and studies, the most frequent are infections with various viruses. Among these are infections with:

Herpes simplex virus 1;
Varicella-zoster virus;
Epstein-Barr virus;
HIV virus;
COVID-19 or influenza B viruses;
Cytomegalovirus;
recurrent upper respiratory tract infections;
Measles virus.

Bell’s facial (peripheral) paralysis can also be triggered by certain chronic diseases, such as diabetes and lung infections. Also, pregnant women can suffer from this disease. However, PFP affects very few people.

Other factors that increase the risk of contracting Bell’s palsy are:

Lyme disease;
tuberculosis;
hypertension;
chronic migraine;
preeclampsia during pregnancy;
Guillain-Barre syndrome;
sarcoidosis.

In addition to these, exposure to cold, obesity, stress, anxiety, and other psychological disorders can lead to the onset of peripheral facial paralysis. At the same time, it is good to realize that certain strong emotions and traumas can trigger this disease.

Bell’s palsy can also occur in the context of autoimmune diseases, and although inherited cases are very rare, they do exist. In most situations, the reactivation of the Herpes virus, which occurs at variable intervals, is responsible for triggering the disease.

What are the symptoms of Bell’s palsy? How can we distinguish between this condition and a stroke (CVA)? There are certain distinctive signs that can indicate the need to consult a doctor, thus allowing prompt initiation of treatment and recovery.

Bell’s Palsy – Clinical Symptoms of the Disease

In most cases, the clinical manifestations of the disease occur suddenly, often in the early part of the day. Both adults and children diagnosed with Bell’s palsy may experience a sensation of paralysis in the facial muscles immediately after waking up. This is when they notice the asymmetry of the face, with a pronounced drooping of the affected side. In adults, the initial thought often turns to a stroke.

Although the signs are obvious, many sensory functions remain intact, thus excluding cerebrovascular pathology. In the case of Bell’s palsy, the involvement is usually limited to only one half of the face.

Besides the previously mentioned symptoms, the following may also occur:

saliva dripping from the droopy side of the mouth;
difficulty closing the eyelid on the affected side, leading to dry eyes;
a feeling of weakness and numbness in the affected half of the face.

Beyond the physical symptoms, sensory ones can also be observed.

People affected by this disease may experience:

facial and jaw pain;
pain behind the ear;
excessive tearing of the unaffected eye;
altered taste;
dry mouth;
difficulty eating and drinking;
noise intolerance.

In addition, ear pain is often one of the symptoms of Bell’s palsy in children.

Besides these symptoms, motor function can be affected by:

inability to frown;
problems closing the affected eye;
lack of ability to smile;
difficulty blowing or pronouncing letters correctly.

When is it necessary to see a doctor? Most often, the clinical manifestations will prompt us to seek immediate medical evaluation for diagnosis and treatment.

Bell’s Palsy – Diagnostic Evaluation, Therapeutic Management, and Recovery

Encouraging news about peripheral facial paralysis is that it can have a favorable course and may resolve spontaneously. However, this recovery process can take several weeks, during which essential functions such as vision and speech may remain affected.

Another reason to avoid self-diagnosis is that the symptoms can be similar to other serious conditions; for example, Bell’s palsy has symptoms that can be confused with stroke, multiple sclerosis, Lyme disease, brain tumors, etc., so seeing a doctor remains the most important step towards healing.

How Bell’s Palsy is Diagnosed

To which specialist should we turn for an accurate diagnosis? The answer is: a neurologist. They will perform a series of tests to properly evaluate the symptoms of the condition. First, they will conduct a medical history to narrow down the list of conditions with similar manifestations. Following this evaluation, they may recommend the following investigations:

blood and serological tests to rule out Lyme disease, HIV infection, or even syphilis;
imaging tests, such as CT and MRI, to rule out brain tumors, trauma, stroke, lesions, or neurological autoimmune diseases;
audiometry to exclude an ear condition;
lumbar puncture, which is performed less frequently.

The condition can present diagnostic challenges, given its idiopathic nature and often unknown causes. Once the doctor confirms the diagnosis of peripheral facial paralysis, they can prescribe appropriate medication. In the context of Bell’s palsy, recovery can be managed much more easily with the correct medication.

Treating Bell’s Palsy with Medications

There is a variety of medications that can be used for Bell’s palsy, primarily consisting of corticosteroids and antivirals. Typically, both types of medications are prescribed for a limited period. They not only help alleviate symptoms but also facilitate a faster recovery process.

In children, Bell’s palsy treatment usually involves the administration of corticosteroids. Antivirals are recommended only if there are Ramsay Hunt type vesicles on the face.

Individuals experiencing a severe form of peripheral facial paralysis may use eye drops to combat dryness of the affected eye. Also, hygiene plays a very important role in recovery after the illness. For this purpose, patients are recommended to apply a sterile patch over the eye to avoid corneal abrasion.

In addition, oral hygiene is also very important, as paralysis can make tooth brushing difficult. However, when done correctly, it will help prevent local infections, which, besides their complications, can also be quite painful.

Although facial nerve decompression is recommended in certain neurological diseases, this is not the case for Bell’s palsy, as it can lead to recovery complications.

Holistic Recovery Methods for Bell’s Palsy

Compared to short-term medications, there are other complementary therapies that are useful in Bell’s palsy. These include:

physiotherapy;
physiotherapy with treatments such as exposure to ultraviolet and infrared rays, short waves, and electrotherapy;
massage;
facial expression exercises to strengthen facial muscles;
thermotherapy.

In most cases, Bell’s palsy resolves within 4 to 5 weeks. When corticosteroids and antivirals are administered, the recovery of the affected nerve is faster. Also, full recovery from the disease can be observed after a period of 1 to 3 months, depending on the patient’s age.

Although recovery can be managed without specific treatment, the option of “letting” the condition heal on its own can lead to various complications.

Complications of Bell’s Palsy

An important aspect to remember about Bell’s palsy is that it can recur. In fact, recurrence is one of the possible complications when the condition is left to heal on its own. Additionally, this approach can delay full recovery, in which case patients may face:

complete paralysis of the face on one or even both sides;
loss of taste and reduced salivation;
hearing impairments;
chronic dry eye;
permanent and irreversible damage to the facial nerve.

These symptoms are frequently encountered in people over 60 years of age.

In conclusion, what is Bell’s palsy? It is an idiopathic neurological disease, as its exact causes are unknown. Most often, it occurs as a result of infection with various viruses, including herpes. However, there are other causes that can lead to the onset of the disease, such as trauma in children. The main symptom of the disease is the drooping appearance of one half of the face, which can resemble a stroke. Although peripheral facial paralysis can resolve on its own, diagnosis and treatment with short-term corticosteroids and antivirals help with faster recovery. Beyond medication, procedures such as physiotherapy, massage, and kinesitherapy can support the regeneration of the facial nerve, avoiding possible complications of Bell’s palsy.
