Middle Ear Infection
The middle ear is lined with a membrane called mucosa. This lining is also connected to the nose and nasopharynx through a tube-like structure known as the Eustachian tube. If this lining becomes inflamed, it is called a middle ear infection (otitis media). Inflammation in the middle ear usually occurs when infections from the nose and nasopharynx reach the middle ear via the Eustachian tube. Middle ear infections commonly develop after conditions such as flu, cold, sinusitis, or upper respiratory tract infections.
Due to the structure of the Eustachian tube, infants and preschool children are more prone to infections. The most common and noticeable symptom is ear pain. The severity of ear pain in children depends on how much the eardrum is stretched due to inflammation. In infants, the pain may be severe enough to wake them from sleep and is often accompanied by high fever.
The main goal of treatment is to allow the infection to resolve naturally. Therefore, medications that open the Eustachian tube and nasal passages are prescribed. Antibiotics, nasal sprays, and pain relievers help recovery. In severe pain cases, surgical procedures such as making a small incision in the eardrum may be necessary.
How Does Middle Ear Infection Occur?
Middle ear infection usually develops as an ascending infection originating from the nose and nasopharynx. Infections in these areas reach the middle ear via the Eustachian tube. Normally, the Eustachian tube remains closed but opens during swallowing due to pressure changes. Swallowing, frequent sucking, and forceful nose blowing can facilitate the spread of infection. It is often associated with infections like sinusitis, flu, and the common cold.
Who is at Risk for Middle Ear Infection?
Middle ear infections are more common in preschool children and infants due to the anatomical structure of the Eustachian tube, which is shorter and more horizontal in children. This makes it easier for infections to spread to the middle ear. Crowded environments such as schools and daycare centers also increase the risk.
What are the Symptoms of Middle Ear Infection?
Severe ear pain is the most prominent symptom. In the acute phase, the pain can be intense enough to wake infants from sleep and is often accompanied by fever. Hearing difficulties may occur due to fluid accumulation. The severity of pain is directly related to the pressure on the eardrum. In some cases, the eardrum may rupture due to pressure, leading to discharge of bloody fluid from the ear, after which the pain subsides.
How is Middle Ear Infection Treated?
The aim of treatment is to allow the infection to clear naturally. Medications to open the Eustachian tube and nasal passages are prescribed. Pain relievers, antibiotics, and nasal sprays help reduce swelling and promote healing. In severe cases, surgical intervention such as eardrum incision may be required.
How Can Middle Ear Infection be Prevented?
Since infections spread from the nose and nasopharynx, preventive measures are important. Adequate rest, proper nutrition, avoiding cold exposure, air pollution, and cigarette smoke are essential, especially for children. Forceful nose blowing should be avoided as it may push infection into the middle ear.
In infants, feeding in a lying position may allow milk to enter the middle ear due to the horizontal position of the Eustachian tube. Additionally, using a pacifier during sleep in infants with upper respiratory infections may facilitate infection spread. Therefore, avoiding pacifier use during sleep can help prevent middle ear infections.
