Bell's Palsy Diagnosis and Management: Comprehensive Guide

Bell’s palsy is a sudden, temporary weakness in your facial muscles, making it difficult to smile or close one eye. It occurs when the nerve that controls your facial muscles becomes inflamed, swollen, or compressed. Diagnosing and managing Bell’s palsy effectively are crucial for optimal recovery. This article provides a detailed overview of Bell’s palsy diagnosis and the various management strategies available.

Diagnosing Bell’s Palsy

There isn’t a single, definitive test to diagnose Bell’s palsy. Instead, healthcare professionals rely primarily on a physical examination. They will carefully observe your face and ask you to perform a series of movements to assess your facial muscle strength and function. These movements typically include:

Closing your eyes tightly
Raising your eyebrows
Showing your teeth
Frowning
Puffing out your cheeks

This physical examination helps healthcare providers identify the characteristic facial weakness associated with Bell’s palsy.

It’s important to note that several other conditions can cause facial muscle weakness that can be mistaken for Bell’s palsy. These conditions include serious issues like stroke, infections (such as viral infections or Ramsay Hunt syndrome), Lyme disease, inflammatory conditions, and tumors. Therefore, if the underlying cause of your facial weakness isn’t immediately clear, your healthcare professional may recommend further testing to rule out these other possibilities.

Diagnostic Tests for Bell’s Palsy (when needed)

While Bell’s palsy diagnosis is often clinical, meaning based on physical examination, additional tests may be necessary in certain cases to confirm nerve damage or exclude other conditions. These tests include:

Electromyography (EMG): This test is used to evaluate the health of muscles and the nerves that control them. During an EMG, a thin needle electrode is inserted into the muscle. The EMG measures the electrical activity of the muscle in response to nerve stimulation. This can help confirm if nerve damage is present, and if so, determine the severity of the damage. It also assesses how well and how fast electrical signals are traveling along the facial nerve.
Imaging Scans: In some instances, imaging scans such as Magnetic Resonance Imaging (MRI) or Computerized Tomography (CT) scans might be recommended. These scans are typically used when your healthcare provider needs to rule out other potential causes of pressure on the facial nerve. Conditions like tumors or skull fractures can sometimes mimic Bell’s palsy symptoms, and imaging can help identify or exclude these.
Blood Tests: There isn’t a specific blood test to diagnose Bell’s palsy itself. However, blood tests can be valuable in ruling out other conditions that can cause facial paralysis, such as Lyme disease and certain other infections. If your healthcare provider suspects an underlying infection, blood tests may be ordered to investigate further.

Bell’s Palsy Treatment and Management

The good news is that most individuals with Bell’s palsy experience a full recovery, often even without specific treatment. There’s no single, universal treatment approach for Bell’s palsy; management is often tailored to the individual and the severity of their symptoms. However, healthcare professionals may recommend medications or physical therapy to help speed up the recovery process and improve outcomes. Surgery is rarely considered an option for Bell’s palsy.

A critical aspect of managing Bell’s palsy, particularly in the initial stages, is protecting the eye on the affected side of the face. Because Bell’s palsy can prevent the eye from closing completely, it’s essential to take proactive steps to keep the eye moist and protected from injury.

Medications

Several types of medications are commonly used in the treatment of Bell’s palsy:

Corticosteroids: Prednisone, and similar corticosteroids, are powerful anti-inflammatory drugs. In Bell’s palsy, it’s believed that swelling of the facial nerve within the narrow bony canal it passes through is a key factor. Corticosteroids work to reduce this swelling. By reducing nerve swelling, corticosteroids can help the nerve function more effectively and improve recovery. For corticosteroids to be most effective, they should ideally be started within a few days of the onset of Bell’s palsy symptoms. Early administration of steroids has been shown to increase the likelihood of a complete recovery.
Antiviral Drugs: The role of antiviral medications in Bell’s palsy treatment is less clear and still debated in the medical community. When used alone, antiviral drugs have not demonstrated a significant benefit compared to placebo in treating Bell’s palsy. However, there is some evidence suggesting that combining antiviral medications with corticosteroids might be beneficial for certain individuals, particularly those with severe facial palsy. Despite the uncertainty, antiviral medications like valacyclovir or acyclovir are sometimes prescribed in conjunction with prednisone, especially in cases of severe Bell’s palsy.

Physical Therapy

When facial muscles are paralyzed due to Bell’s palsy, they can become weakened, shrink (atrophy), and shorten (contracture) over time. In some cases, these changes can become permanent, leading to lasting facial asymmetry or muscle tightness. Physical therapy plays a crucial role in preventing these complications. A physical therapist can teach you specific facial muscle exercises and massage techniques. These exercises help to maintain muscle tone, prevent contractures, and improve coordination as nerve function returns. Starting physical therapy early in the recovery process can be highly beneficial.

Eye Care – Crucial Management

Protecting the eye on the affected side is paramount in Bell’s palsy management. The inability to fully close the eye can lead to dryness, irritation, and potential damage to the cornea (the clear front surface of the eye). Therefore, diligent eye care is essential:

Lubricating Eye Drops: Use lubricating eye drops frequently throughout the day to keep the eye moist.
Eye Ointment: Apply a lubricating eye ointment at night, before bed. Ointments are thicker than drops and provide longer-lasting lubrication.
Glasses or Goggles: Wear glasses or goggles during the day to protect your eye from wind, dust, and other irritants.
Eye Patch: Use an eye patch at night to protect the eye from accidental injury while sleeping. This is especially important to prevent the eye from getting poked or scratched.

Regular monitoring of your eye health by a healthcare professional, such as an ophthalmologist or optometrist, may be necessary to ensure that you are not developing any eye complications.

Surgery (Rarely Considered)

In the past, a surgical procedure called decompression surgery was sometimes used to treat Bell’s palsy. This surgery aimed to relieve pressure on the facial nerve by widening the bony passage it travels through. However, current medical consensus is that decompression surgery is generally not recommended for Bell’s palsy. This is due to the risks associated with the surgery, including potential facial nerve injury and permanent hearing loss, which often outweigh the potential benefits.

In rare cases where Bell’s palsy results in lasting facial nerve problems and significant facial asymmetry or functional impairment, plastic surgery may be considered. Facial reanimation surgery is a type of plastic surgery that aims to improve facial symmetry and potentially restore some degree of facial movement. Examples of facial reanimation procedures include:

Eyebrow lift
Eyelid lift
Facial implants
Nerve grafts

Some of these procedures, such as eyebrow lifts or eyelid lifts, may need to be repeated after several years to maintain their effect.

Lifestyle Adjustments and Home Remedies

In addition to medical treatments, certain lifestyle adjustments and home remedies can help manage Bell’s palsy symptoms and promote comfort during recovery:

Pain Relief

Facial pain or discomfort is a common symptom of Bell’s palsy, particularly in the early stages. Over-the-counter pain relievers can be effective in managing this pain:

Over-the-counter pain relievers: Medications like aspirin, ibuprofen (Advil, Motrin IB), or acetaminophen (Tylenol) can help alleviate mild to moderate pain associated with Bell’s palsy. Always follow the recommended dosage instructions on the medication packaging.

Physical Therapy Exercises at Home

Continuing facial exercises and massage at home, as instructed by your physical therapist, is an important part of the recovery process. Regular exercises can help maintain muscle tone and prevent stiffness.

Alternative Medicine Considerations

While scientific evidence supporting the effectiveness of alternative medicine for Bell’s palsy is limited, some people with the condition find relief from complementary therapies. If you are considering alternative medicine, it’s important to discuss it with your healthcare provider to ensure it’s safe and doesn’t interfere with your conventional medical treatment. Some alternative therapies that have been explored for Bell’s palsy include:

Acupuncture: Acupuncture involves inserting thin needles into specific points on the skin. Proponents suggest that acupuncture can stimulate nerves and muscles, potentially offering some relief from Bell’s palsy symptoms.
Biofeedback Training: Biofeedback is a technique that teaches you to become more aware of and gain control over certain bodily functions, such as muscle tension. Biofeedback training may help some individuals improve voluntary control over their facial muscles during Bell’s palsy recovery.
OnabotulinumtoxinA (Botox): Botox injections are sometimes used to manage specific symptoms associated with Bell’s palsy, such as facial spasms (involuntary muscle contractions) and excessive tearing. Botox can also be used to improve facial symmetry by selectively weakening certain facial muscles.

Preparing for Your Doctor’s Appointment

If you suspect you have Bell’s palsy, it’s important to seek medical attention. Your initial appointment may be with your primary care physician, but you might be referred to a neurologist, a doctor specializing in nervous system disorders. Being well-prepared for your appointment can help you and your doctor make the most of your time together.

What to Do Before Your Appointment

To prepare for your doctor’s appointment, consider the following:

Write down your symptoms: Make a list of all the symptoms you’ve been experiencing, even if they seem unrelated to your facial weakness. Note when the symptoms started and how they have progressed.
Note key personal information: Consider any recent major stresses or life changes you’ve experienced. Sharing this information may be helpful for your doctor in understanding potential contributing factors.
List your medications: Prepare a list of all medications you are currently taking, including prescription drugs, over-the-counter medications, vitamins, and supplements. Include the dosages for each medication.
