What is an Ear Infection?
An ear infection is when bacteria or viruses cause swelling, fluid, or pain in the ear. It can affect different parts of the ear—outer, middle, or inner. Most ear infections are short-term, but some can become chronic or lead to complications if not treated.
There are three main types of ear infections, depending on which part of the ear is affected.
Types of Ear Infections
Here are the common types of ear infections:
- Acute Otitis Media (AOM): This is the most common type. It comes on quickly and often involves pain, swelling, and redness in the eardrum. AOM is often caused by bacteria or viruses.
- Otitis Media with Effusion (OME): This type occurs when fluid builds up in the middle ear without an active infection. It might not be painful, but it can cause muffled hearing. Think of it like having water in your ear after swimming, but it doesn't drain.
- Chronic Otitis Media with Effusion (COME): This is when fluid stays in the middle ear for a long time or keeps coming back, even without symptoms of infection. COME can affect hearing and may require more specialised treatment.
What Causes Ear Infections?
Several factors can lead to ear infections:
- Bacteria:Certain bacteria, like Streptococcus pneumoniae and Haemophilus influenzae, are common culprits behind ear infections.
Viruses: Viruses, such as those that cause the common cold or flu, can also lead to ear infections. - Allergies: Allergies can cause inflammation and congestion in the nasal passages and Eustachian tubes, making it easier for fluid to get trapped in the middle ear. Colds and other respiratory infections: These illnesses can also block the Eustachian tubes, increasing the risk of ear infections.
- Colds and other respiratory infections: These illnesses can also block the Eustachian tubes, increasing the risk of ear infections.
- Smoking and secondhand smoke: Smoke irritates the lining of the Eustachian tubes and can contribute to ear infections, especially in children.
- Eustachian tube dysfunction: This occurs when the Eustachian tubes don't open and close properly, leading to fluid buildup.
Signs and Symptoms of an Ear Infection
Ear infections often present with a range of symptoms:
- Ear pain: This is often the most noticeable symptom, especially in acute otitis media. The pain can range from a dull ache to a sharp, throbbing sensation.
- Drainage from the ear: You might see a yellowish or greenish fluid draining from the ear. This is a sign of infection.
- Muffled hearing: Fluid in the middle ear can block sound waves, making it difficult to hear clearly.
- Sore throat: The infection can sometimes spread to the throat, causing pain and irritation.
- Fever: A fever, especially in children, can be a sign of an ear infection.
Irritability, loss of appetite, and difficulty sleeping (in children). These symptoms can be indicators of an ear infection in younger children who may not be able to express their discomfort verbally.
How Are Ear Infections Diagnosed?
Diagnosing an ear infection is important to ensure appropriate treatment. Here are common methods used:
- Physical Examination: The doctor will examine the ears, throat, and nose to look for signs of infection, like redness, swelling, and fluid.
- Otoscope: This is a handheld instrument with a light and magnifying lens that allows the doctor to look inside the ear canal and examine the eardrum. They'll look for signs of inflammation, fluid, and bulging.
- Tympanometry: This test measures the movement of the eardrum in response to changes in air pressure. It helps determine if there is fluid behind the eardrum.
- Pneumatic otoscopy: The doctor uses a special otoscope with a bulb to gently puff air into the ear canal. This allows them to see how the eardrum moves, helping to identify fluid buildup.
In rare cases, fluid from the ear may be tested. If the infection is severe or doesn't respond to treatment, the doctor might take a sample of fluid from the middle ear to test for bacteria or fungus. This helps determine the specific cause of the infection and guide treatment.
What is the treatment of ear infection?
Treatment for ear infections depends on the severity and type of infection. Many ear infections resolve on their own without antibiotics, especially in older children and adults. Treatment focuses on managing symptoms and supporting the body's natural healing process.
- Observation (watchful waiting): For mild ear infections, the doctor may recommend monitoring the symptoms for a few days to see if they improve on their own. This allows the body's immune system to fight the infection naturally.
- Pain relief: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help reduce pain and fever. Warm compresses applied to the ear can also provide comfort.
- Antibiotics: Antibiotics are sometimes prescribed for severe ear infections, infections that don't improve with watchful waiting, or in younger children. It's important to complete the full course of antibiotics even if symptoms improve.
Primary Surgical Procedures
Here are some of the primary surgical procedures for ear-related issues:
- Myringotomy (Small Incision for Drainage): This procedure involves creating a small incision in the eardrum to drain trapped fluid. It's a relatively quick procedure, taking about 15-20 minutes and performed under general anaesthesia. The typical recovery period is approximately four weeks. This procedure offers quick relief from pain and pressure caused by fluid buildup.
- Tympanostomy (Ear Tubes for Ventilation and Drainage): In this procedure, small tubes are inserted into the eardrums to facilitate fluid drainage and ventilation. These tubes typically fall out on their own after 6-18 months. This procedure is commonly performed in children between the ages of 1 and 3 who experience recurrent ear infections. The tubes help equalise pressure and prevent fluid buildup in the middle ear.
- Tympanoplasty (Eardrum Repair): This surgical procedure repairs a perforated (torn or ruptured) eardrum using a tissue graft. Tympanoplasty boasts a high success rate of 93% in treating ruptured eardrums, helping restore hearing and prevent recurrent infections. The recovery period is relatively short, usually taking about 10-14 days. The procedure helps restore the eardrum's protective function and improve overall ear health.

Advanced Surgical Procedures
More advanced surgical ear procedures include:
- Mastoidectomy (Removal of Mastoid Bone Infection): Mastoidectomy is a surgical procedure to remove an infection from the mastoid bone located behind the ear. This procedure is often combined with tympanoplasty if the eardrum is also affected. It becomes necessary when the infection spreads to the skull bone, a serious complication of untreated or persistent ear infections. The procedure helps prevent further complications and preserves hearing function.
- Ossiculoplasty (Reconstruction of Middle Ear Bones): Ossiculoplasty is a surgical procedure to reconstruct damaged or missing ossicles (tiny bones) in the middle ear. It utilises a prosthesis to restore sound transmission and improve hearing. This is typically necessary when the ear bones are damaged by infection, trauma, or other conditions that disrupt their function. This procedure is crucial for restoring hearing and preventing long-term hearing impairment.
FAQs
Most ear infections clear up within a week or two. SCI hospitals offer comprehensive care to help you recover comfortably. If your symptoms last longer or worsen, schedule a follow-up appointment at SCI. We can adjust your treatment plan as needed.
Protect your ears during recovery. Avoid putting anything in your ears, including cotton swabs. Also, try not to blow your nose too hard. This can worsen ear pressure and discomfort. If you have any concerns, contact SCI Hospitals for guidance.
It's best to avoid swimming until your ear infection is completely healed. This helps prevent further irritation or infection. The experts at SCI Hospitals can advise you when it's safe to swim again based on your individual recovery. Schedule a consultation for personalised advice.
Over-the-counter pain relievers can help manage ear pain. A warm compress against your ear may also provide comfort. If pain persists, contact SCI Hospitals. We can explore additional pain management options tailored to your needs. Don't hesitate to call or book an appointment online.
