Juvenile Recurrent Parotitis

What is juvenile recurrent parotitis?

Juvenile recurrent parotitis is a condition in which one of the parotid glands, the large saliva-producing glands that sit just in front of and below each ear, becomes swollen and painful again and again during childhood. The word parotitis simply means inflammation of the parotid gland, and recurrent means the episodes come back after settling down. The condition is non-obstructive, meaning it is not caused by a stone blocking the saliva duct, and it is usually non-suppurative, meaning the gland is inflamed but not filled with pus.

Most children who develop juvenile recurrent parotitis have their first episode between the ages of about three and six, although it can appear earlier or later. Boys are reported to be affected somewhat more often than girls. After mumps, it is considered one of the more common inflammatory salivary gland conditions in children. Episodes typically affect one side at a time, although the other side may be involved in later flares, and in some children both glands swell together.

For many families, the most reassuring fact about juvenile recurrent parotitis is that it tends to become less frequent as the child grows, and in a large proportion of cases the episodes stop around puberty. Because the condition involves the salivary glands of the head and neck, it is usually assessed and managed by an ear, nose and throat specialist, sometimes together with a pediatrician. At Acibadem, this falls within the Otorhinolaryngology (ENT) department.

Juvenile recurrent parotitis symptoms

Juvenile recurrent parotitis symptoms come in episodes, often called flares or attacks, separated by periods when the child feels completely well. A typical flare builds up over a day or two, lasts anywhere from a few days to about two weeks, and then fades. Common features include:

• Swelling in front of and below one ear, over the angle of the jaw
• Pain or tenderness in the swollen area, which may worsen when eating
• A warm or slightly reddened feel to the skin over the gland
• Mild fever, or sometimes no fever at all
• Dry mouth or reduced saliva on the affected side
• Cloudy or slightly thickened saliva coming from the duct opening inside the cheek
• General tiredness, irritability or reduced appetite during a flare
• Occasionally a bad taste in the mouth

Between episodes, the gland usually returns to a normal or near-normal size and the child has no symptoms. The gap between flares varies widely; some children have several attacks a year, while others go many months without one. Over years, repeated inflammation can leave the gland feeling slightly firm or enlarged even when the child is well, but this is not the case for every child.

It is useful to distinguish juvenile recurrent parotitis from an acute bacterial parotitis, which is a single sudden infection of the gland. Bacterial infection is more likely to cause high fever, marked redness, severe pain and visible pus at the duct opening. Because the two can look similar at the start of an episode, doctors usually keep bacterial infection in mind, particularly during a first attack.

Causes and risk factors

The exact juvenile recurrent parotitis causes are not fully understood, and most specialists believe several factors act together rather than a single cause being responsible. The following explanations are commonly discussed:

• Structural changes in the gland: Imaging often shows sialectasis, which means widening of the tiny ducts inside the gland. Whether this widening is present from birth or develops after early episodes of inflammation is still debated.
• Reduced saliva flow: Saliva normally flushes bacteria out of the duct. If flow is slow, for example because of dehydration or a naturally narrow duct, bacteria from the mouth may travel up into the gland more easily.
• Low-grade infection: Bacteria that live normally in the mouth may repeatedly irritate a gland that is already vulnerable.
• Immune factors: Some researchers have suggested an allergic or immune component, and in a small number of children recurrent parotitis turns out to be an early sign of an autoimmune condition such as Sjögren syndrome, in which the immune system attacks moisture-producing glands.
• Genetic tendency: A family history is sometimes reported, suggesting inherited factors may play a role in some children.

Risk factors that may make episodes more likely or more frequent include being a young child in the preschool to early school years, being male, having a family member with the same condition, becoming dehydrated during hot weather or illness, poor oral hygiene, and having an underlying immune disorder. Juvenile recurrent parotitis is not contagious, and it is not caused by anything a parent did or failed to do.

Diagnosis

Juvenile recurrent parotitis diagnosis is based mainly on the pattern of the child's symptoms over time, supported by an examination and, in most cases, an ultrasound scan. There is no single blood test that proves the condition. Instead, doctors look for the typical story of repeated, self-limiting swelling of the parotid gland and rule out other explanations.

The steps usually include:

• Medical history: The doctor asks how many episodes there have been, how long each lasted, which side was affected, whether there was fever, and whether the child has been vaccinated against mumps.
• Physical examination: The gland is gently felt for size, tenderness and warmth. Inside the mouth, the doctor may massage the gland and watch the duct opening to see whether clear, cloudy or pus-like saliva emerges.
• Ultrasound: This painless scan is the most commonly used imaging test in children. In juvenile recurrent parotitis it often shows an enlarged gland with multiple small dark areas that correspond to widened ducts. Ultrasound also helps rule out a stone, an abscess or a mass.
• Blood tests: These may be used to check for signs of infection, to test for mumps antibodies during a first episode, and in some cases to look for autoimmune markers linked to Sjögren syndrome or for other conditions such as HIV infection, which can also enlarge the parotid glands.
• Sialography: In this older test, a small amount of contrast dye is placed into the duct and an X-ray is taken, showing a characteristic pattern of small pooled dots along the duct system. It is used less often in children today because ultrasound is simpler.
• Sialendoscopy: A very thin telescope is passed through the natural duct opening in the cheek to look directly inside the duct. It can confirm the diagnosis and, as described below, is often used for treatment at the same time. It usually requires sedation or general anesthesia in young children.
• MRI or CT: These are reserved for unusual presentations, for example when a mass is suspected or the picture is not clear.

Because a first episode of parotid swelling can also be mumps or an acute bacterial infection, a confident diagnosis of juvenile recurrent parotitis is often only made once a child has had two or more episodes with a typical course.

Treatment options

Juvenile recurrent parotitis treatment aims to relieve symptoms during a flare, shorten episodes where possible, reduce how often they return, and protect the gland from long-term damage. Because the condition often improves on its own with age, most doctors start with the least invasive measures and move to procedures only if attacks are frequent or severe.

Supportive care during an episode

For most flares, simple measures are the mainstay of treatment:

• Encouraging plenty of fluids to keep saliva flowing
• Warm compresses applied to the swollen area
• Gentle massage of the gland, stroking forward toward the mouth, to help move saliva along the duct
• Sialogogues, which are things that stimulate saliva such as sugar-free sour candies or chewing gum, if the child is old enough to use them safely
• Over-the-counter pain relievers appropriate for the child's age and weight, such as acetaminophen or ibuprofen, as advised by a doctor or pharmacist
• Good tooth brushing and general mouth care

Medications

Antibiotics are not always necessary, because many episodes are not primarily bacterial. However, doctors often prescribe a short course when there is fever, pus from the duct, or concern about bacterial infection, and some prescribe them routinely at the start of each flare in the hope of shortening it. Short courses of oral corticosteroids, which are anti-inflammatory medicines, are sometimes used, although evidence for their benefit is limited. Long-term preventive antibiotics are generally avoided in children because of side effects and resistance.

Sialendoscopy

Sialendoscopy has become the most widely used procedure for children with frequent episodes. Under anesthesia, a thin endoscope is passed into the duct, the duct system is flushed with saline to wash out debris and mucus plugs, and a steroid solution may be instilled directly into the gland. Narrowed segments can sometimes be gently widened. Many children have fewer or milder episodes after sialendoscopy, and it can be repeated if needed. It does not involve any external cut and is considered gland-preserving.

Other procedures

Some clinicians perform duct irrigation with saline or contrast without an endoscope, and the sialography test itself has been observed to reduce symptoms in some children, possibly through a washing effect. Surgery to remove the parotid gland (parotidectomy) or to tie off the duct is rarely considered in childhood because of the risk to the facial nerve, which runs through the gland, and because most children improve naturally over time. It is usually reserved for older patients with persistent, disabling disease.

Managing an underlying condition

If tests suggest Sjögren syndrome or another immune disorder, the child may be referred to a pediatric rheumatologist, and treatment then focuses on that condition as well as on the gland itself.

Living with juvenile recurrent parotitis and outlook

The overall outlook for juvenile recurrent parotitis is generally favorable. In many children the episodes gradually become less frequent and less severe through later childhood, and a large proportion stop having attacks altogether around the time of puberty. Doctors cannot predict exactly when this will happen for an individual child, and a minority continue to have episodes into adulthood or are left with a gland that produces less saliva than normal.

Day to day, families often find that a few habits help: keeping the child well hydrated, especially in hot weather or during other illnesses; maintaining regular tooth brushing and dental checkups; and recognizing the early signs of a flare so that warmth, massage and fluids can be started promptly. Keeping a simple diary of episodes, including dates, side affected and duration, can be very helpful for the treating team when deciding whether a procedure such as sialendoscopy is worth considering.

Juvenile recurrent parotitis does not spread to other people, and children can usually attend school and take part in normal activities once they feel well enough. Repeated swelling can be upsetting for a child, and reassurance that the condition is well recognized and tends to improve with age is an important part of care.

Frequently asked questions

What are the first juvenile recurrent parotitis symptoms parents usually notice?

The first sign is usually a soft, tender swelling in front of and below one ear that appears over a day or so, sometimes with mild fever or fussiness. The child may complain that it hurts to chew. Because the first episode looks very similar to mumps or a bacterial gland infection, a doctor will often want to examine the child and may order tests before settling on a diagnosis.

Is juvenile recurrent parotitis the same as mumps?

No. Mumps is a contagious viral infection that usually causes a single episode of parotid swelling, often on both sides, and is preventable with vaccination. Juvenile recurrent parotitis is not contagious and, by definition, keeps coming back. A first episode of parotid swelling in an unvaccinated child may prompt a blood test for mumps to tell the two apart.

What are the most likely juvenile recurrent parotitis causes?

The cause is not fully known. Most experts think that widened small ducts inside the gland, reduced saliva flow and low-grade bacterial irritation from the mouth combine to produce repeated inflammation. In a small number of children an immune condition such as Sjögren syndrome is found, which is one reason doctors sometimes order blood tests.

How is juvenile recurrent parotitis diagnosis confirmed?

Diagnosis is mainly clinical, based on a history of two or more self-limiting episodes of parotid swelling, supported by an ultrasound scan that typically shows an enlarged gland with multiple tiny widened ducts. Blood tests may be used to exclude mumps, bacterial infection and autoimmune disease. Sialendoscopy can confirm the picture directly and is often combined with treatment.

What is the standard juvenile recurrent parotitis treatment?

Most episodes are managed with fluids, warm compresses, gentle gland massage, saliva-stimulating candies or gum, and age-appropriate pain relief. Antibiotics are used when infection is suspected. For children with frequent or severe attacks, sialendoscopy with duct washing and steroid instillation is commonly offered, and many children have fewer episodes afterward. Surgery is rarely needed.

Will my child grow out of juvenile recurrent parotitis?

In many cases, yes. Episodes often become less frequent with age and frequently stop around puberty. However, this cannot be guaranteed for every child, and a small number continue to have symptoms in adulthood. Regular follow-up allows the treating team to adjust the plan if attacks persist.

Can anything prevent juvenile recurrent parotitis flares?

There is no proven way to prevent the condition itself. Staying well hydrated, keeping good oral hygiene and using saliva-stimulating measures may help reduce the number or severity of flares in some children, and sialendoscopy is sometimes used specifically to lower the frequency of attacks.

When to see a doctor

Any child with unexplained swelling of the face or neck should be assessed by a doctor, especially during a first episode when other causes such as mumps, bacterial infection or, rarely, a growth need to be excluded. Children with a known diagnosis of juvenile recurrent parotitis should be reviewed if episodes become more frequent, last longer than usual, or start affecting daily life, as this may change the treatment plan.

Seek urgent medical attention if any of the following red-flag signs appear:

• High fever, or a fever that does not settle with usual measures
• Rapidly increasing swelling, or skin over the gland that becomes very red, tense or shiny
• Severe pain that is not controlled by age-appropriate pain relief
• Difficulty opening the mouth, swallowing or breathing
• Drooling, inability to drink, or signs of dehydration such as very little urine, dry lips or unusual drowsiness
• Pus draining from inside the cheek or through the skin
• Weakness or drooping of one side of the face, which may indicate involvement of the facial nerve
• A hard lump in the gland that persists between episodes or keeps growing
• Swelling that appears on both sides together with dry eyes, joint pain or other symptoms suggesting a wider illness

These signs may indicate an abscess, a spreading infection or another condition that needs prompt evaluation and treatment rather than home care alone.
