What Is Ramsay Hunt Syndrome?
The disorder was discovered by Dr. James Ramsay Hunt and was named after him. Ramsay Hunt syndrome is the combination of a characteristic ear rash (herpes zostic oticus) and facial paralysis. Ramsay Hunt syndrome has equal predilection in males and females. Many of the cases of this syndrome go either undiagnosed or misdiagnosed, making it difficult to determine the frequency of the disorder in the general population.
What Are the Causes of Ramsay Hunt Syndrome?
It is caused by the varicella-zoster virus (VZV). This virus also causes chickenpox in children and shingles (herpes zoster) in adults. In the case of Ramsay Hunt syndrome, there is a reactivation of the virus from the previous chickenpox infection. The virus remains inactive (dormant) for years until it is reactivated again to cause shingles. Shingles that affect the facial nerve near one of the ears are known as Ramsay Hunt syndrome. The reason behind the reactivation of the virus and its effect on the facial nerve in Ramsay Hunt syndrome is unknown.
What Are the Symptoms of Ramsay Hunt Syndrome?
The two main characteristic symptoms of Ramsay Hunt syndrome, which usually present unilaterally, are:
-
A painful red rash with fluid-filled blisters around one ear.
-
Facial paralysis and the associated weakness are seen on the same affected side. In general, the rash and the facial paralysis occur at the same time. Sometimes, one can precede the other. In some instances, the rash never occurs.
Other associated symptoms include:
-
Pain associated with the ear.
-
Hearing disability.
-
Tinnitus: Ringing in the ears.
-
Difficulty closing one eye.
-
Vertigo: A sensation of spinning.
-
An altered perception of taste or loss of taste.
-
Dryness is seen in the mouth and eyes.
Upon paralysis of the facial nerve, the facial muscles are affected and may be weak or stiff. This results in their inability to smile, wrinkle their forehead, or close their eye on the affected side. Speech may become slurred in some cases.
Herpes zostic oticus is a reddish (erythematous), painful, blistering (vesicular) rash that affects the pinna (the outer portion of the ear) and the external ear canal. In some instances, the rash includes painful blisters that may affect the mouth, soft palate, and top portion of the throat.
In some individuals, Ramsay Hunt syndrome may present with facial palsy associated with varicella-zoster (confirmed by testing (e.g., blood tests)) but with no associated dermal presentations. It may be referred to as zoster sine herpete.
Other symptoms affecting the ear include ringing in the ear (tinnitus) and ear pain (otalgia), which may be intense. The virus may spread and affect the neck as well. A condition where sound vibrations are not properly transmitted to the brain due to a defect of the inner ear or the auditory nerve (sensorineural hearing loss) can be noted in a few infected individuals. This leads to hearing loss that is usually temporary (transient), but, in some cases, it may become permanent. A few affected individuals may experience hyperacusis, where sounds appear dramatically louder than normal and cause extreme discomfort.
Who Is Affected by Ramsay Hunt Syndrome?
Anyone with shingles or chickenpox may be susceptible to Ramsay Hunt syndrome. Most cases affect persons 60 years of age and older. Though it seldom affects kids, the illness has been identified in those as young as three. Immunocompromised individuals are more susceptible to infection and typically have more severe symptoms. Additionally, their chances of fully recovering are lower.
Is Ramsay Hunt Syndrome Spreadable?
The Ramsay Hunt syndrome is not transmissible. However, having the illness indicates that one could have the varicella-zoster virus. When an afflicted person develops blisters, their fluid may come into touch with others, potentially spreading the infection. In persons who have never had the illness or had the vaccination, it is possible to induce chickenpox. Staying out of a specific group of individuals is advisable until the blisters heal. Among these are:
-
Those who have never had the chickenpox vaccination or suffered the illness.
-
Those whose immune systems are compromised.
-
Infants.
-
Individuals who are pregnant.
How Is Ramsay Hunt Syndrome Diagnosed?
A confirmed diagnosis of Ramsay Hunt syndrome is made by combining the evidence from a detailed patient history, a thorough clinical evaluation, and identifying characteristic symptoms. It is to be noted that the symptoms of the disorder (otalgia, facial paralysis, and the distinctive rash) do not always develop at the same time. Therefore, the doctor could ask for a laboratory test to affirm the diagnosis. They might take a blood sample, saliva, or blister fluid. The sample will be examined under a microscope for the varicella-zoster virus.
What Are the Complications of Ramsay Hunt Syndrome?
-
Permanent Hearing Loss and Facial Weakness: For most people, hearing loss and facial paralysis are temporary. However, in some patients, it can become permanent.
-
Eye Damage: The facial weakness associated with Ramsay Hunt syndrome may make it difficult to close the eyelid. Excessive opening of the eyes causes abnormal dryness, which leads to damage to the cornea (which protects the eye) and can cause eye pain and blurred vision.
-
Postherpetic Neuralgia: This is a painful condition that occurs when shingles infection damages the nerve fibers. It causes pain that may last long after other signs and symptoms of Ramsay Hunt syndrome have resolved.
How Can Ramsay Hunt Syndrome Be Prevented?
Routine vaccination of children against chickenpox greatly reduces the chances of becoming infected with the chickenpox virus. A shingles vaccine is recommended for people over 50 or older.
What Are the Risk Factors of Ramsay Hunt Syndrome?
Anyone who has had chickenpox is susceptible to Ramsay Hunt syndrome. It usually affects those over 60 and is more prevalent in older persons. In children, Ramsay Hunt syndrome is uncommon.
What Is the Difference Between Ramsay Hunt Syndrome and Bell’s Palsy?
Bell's palsy and Ramsay Hunt syndrome both result in facial paralysis, but they are not the same. The cause of Ramsay Hunt syndrome is herpes zoster infection. There is no known cause of Bell's palsy. In patients with Ramsay Hunt syndrome, paralysis is more severe at first, and recovery is much less probable than in Bell's palsy (facial paralysis without rash). In Ramsay Hunt syndrome, facial paralysis is accompanied by an excruciating red rash around the ears and ear discomfort; early therapy can lead to a full recovery. In contrast, Bell's palsy causes abrupt paralysis or weakening of the face without any rash; many people, even without treatment, make a full recovery.
What Are the Treatment Options Available for Ramsay Hunt Syndrome?
The treatment of Ramsay Hunt syndrome commonly involves administering the following drugs in conjunction:
-
Antiviral medications, like Acyclovir or Famciclovir.
-
Corticosteroids, like Prednisone.
Antiviral treatment is advised to be given within three days of the onset of the symptoms. Timely diagnosis and accurate patient management drastically improve treatment outcomes. In some cases, despite therapy, some degree of facial paralysis and hearing loss may become permanent.
Palliative care is directed towards specific symptoms that are apparent in each patient. This includes medications for pain. Carbamazepine (an anti-seizure medicine) is used to reduce neuralgic pain, and in the case of vertigo, suppressants like antihistamines and anticholinergics are administered. As corneal drying is associated with the syndrome, artificial tears and lubricating ointments may be prescribed.
Does Ramsay Hunt Syndrome Come Back?
Although extremely uncommon, Ramsay Hunt syndrome has the same potential to recur as shingles. This is due to the varicella-zoster virus's permanent presence in the nerves.
Conclusion:
Ramsay Hunt syndrome can develop as a shingles-related aftereffect. Facial paralysis, excruciating agony, and a rash are possible side effects of the illness. With early diagnosis and treatment, the likelihood of recovering completely is higher. Patients with Ramsay Hunt syndrome must be treated within three days once they begin experiencing symptoms to recover completely from the disease.
