Ramsay Hunt syndrome and facial paralysis: symptoms, causes and the role of specialised physiotherapy

What is Ramsay Hunt Syndrome?

Ramsay Hunt syndrome is a neurological condition caused by the reactivation of the varicella-zoster virus, the same virus responsible for chickenpox and shingles. When this reactivation involves the facial nerve, it can lead to paralysis of one side of the face, intense ear pain, and a painful skin rash.

It is considered one of the potentially most serious causes of peripheral facial paralysis, requiring prompt medical evaluation to reduce the risk of complications and improve functional prognosis.

What are the main symptoms?

The most frequent signs and symptoms include:

• Severe ear pain
• Rash with small vesicles on the auricle, ear canal or oral cavity
• Unilateral facial paralysis
• Difficulty closing eye
• Changes in taste
• Vertigo
• Hearing loss
• Tinnitus

In some cases, a rash may not be present, which can make diagnosis difficult. The sudden onset of these symptoms warrants immediate medical evaluation.

A Síndrome de Ramsay-Hunt é causada pelo vírus varicela-zóster (VVZ), o mesmo vírus que causa a catapora.

The syndrome results from the reactivation of the varicella-zoster virus, which remains latent in the nerve ganglia after the initial chickenpox infection. When reactivated, it can affect the facial nerve and adjacent structures, causing inflammation, pain, and motor deficit.

Factors such as stress, Decreased immunity, advanced age, and chronic illnesses can increase the risk of viral reactivation.

Is Ramsay Hunt Syndrome contagious?

The syndrome itself is not contagious. However, the varicella-zoster virus can be transmitted to people who have never had chickenpox or who have not been vaccinated. In these cases, the exposed person may develop chickenpox, but not the syndrome.

The skin vesicles are the main source of transmission, making it important to protect them and follow medical advice.

How is the diagnosis made?

The diagnosis is essentially clinical, based on the association between ear pain, facial paralysis, and a characteristic vesicular rash. Further tests, such as electromyography, may be performed to assess the degree of facial nerve involvement.

In certain situations, laboratory tests can help confirm the presence of the virus.

What is the recommended medical approach?

Medical intervention should be initiated as early as possible. It usually includes antivirals, corticosteroids, and analgesics, with the aim of reducing inflammation, controlling pain, and limiting nerve damage.

Early intervention is associated with a better clinical outcome.

Is specialised physiotherapy important in Ramsay Hunt Syndrome?

Yes. After the acute phase is controlled, specialised physiotherapy for facial paralysis plays a relevant role in functional recovery.

The intervention focuses on:

• Neuromuscular re-education of the face
• Improvement of mobility and coordination
• Prevention of synkinesis, contractures, and spasms
• Muscle tension reduction

Gentle mobilisation techniques, manual therapy, coordination training and relaxation strategies can be used, always adapted to the stage of progression and individual needs.

How long can recovery take?

Evolution varies significantly between people. In many cases, gradual improvement is observed in the first few weeks. However, Ramsay Hunt syndrome tends to have a more reserved prognosis when compared to Bell's palsy, with neuromuscular reorganisation potentially prolonging for several months.

In more extensive situations, sequelae may persist which benefit from specialist follow-up.

What are the possible complications?

The most frequent complications include:

• Synaesthesia
• Persistent neuropathic pain
• Prolonged facial weakness
• Difficulty closing the eye
• Sound hypersensitivity
• Tinnitus
• Vertigo

Early medical assessment and follow-up by a specialist physiotherapist reduce the risk of long-term complications.

When to seek medical help?

It is essential to seek medical evaluation for severe ear pain, facial paralysis, rash, or a combination of these symptoms. Early diagnosis and timely intervention are crucial for the prognosis.

Understanding Ramsay Hunt Syndrome from an integrative perspective

Ramsay Hunt syndrome is a complex condition that requires rigorous diagnosis, early medical intervention, and specialist follow-up. Physiotherapy specialising in facial paralysis is integrated into the functional recovery process, supporting neuromuscular reorganisation and the improvement of facial control.

At Integrativa physiotherapy specialising in facial paralysis It is based on a detailed clinical assessment of mobility, symmetry, coordination, and functional impact, allowing for the delineation of an individualised approach tailored to the stage of development.

In the presence of symptoms suggestive of facial paralysis or suspected Ramsay Hunt Syndrome, early professional evaluation is essential to guide the clinical pathway safely and in a structured manner.
