Sometimes, an ear infection can come back again and again. These are called chronic or recurring ear infections.
In this article, we look at the different types of ear infections and what makes them chronic. We also discuss the ways to treat and prevent a chronic ear infection.
Viruses cause most ear infections, although sometimes bacteria are the culprit. There are three main types of ear infections that affect the middle ear:
- Acute otitis media (AOM) is the most common type of ear infection. Fluid builds up behind the eardrum, causing a painful earache.
- Otitis media with effusion (OME) usually occurs in children. It develops after an original ear infection has resolved, but fluid remains trapped in the middle ear. A child may not have any symptoms, but a doctor can see signs of fluid behind their eardrum.
- Chronic otitis media with effusion (COME) is when fluid stays in the ear for an extended period or keeps coming back. Someone with COME often finds it harder to fight off new ear infections and may have some trouble hearing. A doctor will diagnose COME after a person has had OME for
3 or more months.
Another form of chronic ear infection is called chronic suppurative otitis media (CSOM). People with CSOM have recurring and persistent ear discharge. The condition
People with untreated or chronic ear infections can develop several complications. Repeated ear inflammation can cause the following conditions:
- Mastoiditis, which is an uncommon condition that causes AOM symptoms as well as redness or swelling behind the ear.
- Cholesteatoma, which is a growth of skin cells in the middle ear, often due to recurrent ear infections.
A person's symptoms will differ depending on the type of ear infection they have. The symptoms may be present in one or both ears and may come and go.
A chronic ear infection usually develops when a person has:
- an acute ear infection (AOM) that does not completely heal
- repeated ear infections
Symptoms of an acute ear infection
The symptoms of an acute ear infection include:
- ear pain
- hearing problems
- fever of 100.4°F or higher
- nausea or vomiting
- ear discharge
Children may also show signs of irritability. They may also cry more frequently and tug at the affected ear.
Symptoms of chronic ear infections
Someone with a chronic ear infection does not usually have any visible symptoms. However, long-term OME can cause hearing problems and other difficulties, particularly in children. These include:
- delayed responses, or taking a long time to understand speech
- difficulties speaking or reading
- poor balance
- limited attention
- less ability to work independently
Doctors consider OME to be chronic if it lasts for
According to a 2016 guideline, OME usually disappears by itself within 3 months.
They also report that 30–40 percent of children experience OME more than once, and 5–10 percent of episodes last for 1 year or longer.
When someone has CSOM, they have a hole in their eardrum. When the eardrum bursts, it releases tension, so not everyone with CSOM will feel
The symptoms of CSOM include:
- hearing loss
- leaking fluid from the ear
- a hole in the eardrum
People with CSOM are unlikely to have a fever.
Chronic ear infections develop from a long-lasting or recurrent acute ear infection. Preventing acute ear infections can help prevent chronic ear infection.
Acute ear infections happen when the eustachian tube, a tube that runs from the middle ear to the back of the throat, becomes clogged.
Children are more likely to be affected by ear infections because these tubes are shorter and narrower, so they become clogged more easily.
Fluid build-up in the middle ear can become infected, which will cause pain and other symptoms.
Causes of ear infections
- bacterial infection
- the common cold
- the flu
Risk factors for chronic ear infections include:
- a recent upper respiratory tract infection
- Down syndrome
- having a cleft palate
- a family history of ear infections
Busy day-care centers can also increase the risk of children developing ear infections, as they come into more contact with viruses and bacteria.
Some ear infections resolve on their own, while others may need further treatment. Anyone who still has an ear infection after several days should seek medical attention to find out the type of ear infection they have.
Generally, OME goes away
Treatments for chronic ear infections include the following:
Dry mopping, also called an aural toilet, is when a doctor flushes and cleans the ear of wax and discharge.
Doctors think this speeds up recovery from some types of chronic ear infections, such as CSOM, as it keeps the ear canal free of debris and discharge.
People who have an ear infection may find relief in taking over-the-counter pain and fever reduction medication, such as acetaminophen or non-steroidal anti-inflammatories (NSAIDs). Children should not take aspirin.
Antibiotics only work if bacteria are the cause of the infection, and may not be helpful for people with chronic ear infections.
People with infections that have resulted in a punctured eardrum or a hole in the middle ear, such as CSOM, may benefit from prescribed antibiotic ear drops, such as ciprofloxacin.
However, antibiotics can have side effects, so taking them unnecessarily can make a person feel worse, rather than better. Also, over time, the bacteria that cause some ear infections can become more resistant to antibiotics.
Doctors may recommend antifungal ear drops or ointments if a fungal infection causes a person's symptoms.
An ear tap
Also known as tympanocentesis, an ear tap involves removing fluid from behind the eardrum and testing the fluid to identify what is causing the ear infections.
In situations where a person has a recurring ear infection or one that does not respond to treatment, a doctor might perform a surgical procedure to insert a pressure equalization (PE) tube into the eardrum.
This allows fluid to move out of the middle ear and relieves pressure in the eardrum. Sometimes, these tubes fall out on their own, other times a doctor will need to remove them.
An adenoidectomy is a procedure to remove the adenoids. The adenoids are glands at the back of the nose that help fight infections.
However, if they become enlarged due to an infection, they can cause an earache and a build-up of fluid.
If this happens regularly, a doctor may perform an adenoidectomy to help reduce chronic ear infections.
According to a
The following tips may help prevent relapses of chronic ear infections:
- Stay away from cigarette smoke. Smoke and secondhand smoke can irritate the eustachian tube. This increases the number and duration of ear infections.
- Avoid using cotton swabs or Q-tips. Putting any object into the ear, particularly the ear canal, can damage the sensitive structures in the ear and increase the chance of injury, disrupt the ear's natural
cleansing mechanism, and push earwax further into the ear canal.
- Wash your hands regularly. Avoiding contact with bacteria and viruses will help the body stay healthy and avoid ear infections.
Different types of chronic ear infections require different treatments. Many resolve without treatment.
The American Academy of Otolaryngology recommend watchful waiting to delay prescribing antibiotics for chronic ear infections that are caused by bacteria. However, doctors may prescribe them for some acute ear infections
Always consult a doctor when experiencing symptoms of an ear infection. Be sure to make another visit if an ear infection gets worse, lasts more than 3 days, or symptoms change.
