What is Bacterial Ear Infection?
A bacterial ear infection is an infection of the inner or outer ear caused by bacteria. It is also known as otitis media or external otitis. Ear infections are one of the most common childhood illnesses, but they can affect people of all ages. They can cause pain, hearing loss, and other symptoms. Treatment usually involves antibiotics.
Signs and Symptoms
The signs and symptoms of a bacterial ear infection vary depending on the type and location of the infection. Common symptoms include:
- Earache
- Pain in the affected ear
- Fever
- Headache
- Muffled hearing
- Swelling and redness around the ear
- Discharge from the ear
- Itching or irritation of the ear
Causes
Bacterial ear infections are caused by bacteria, such as Streptococcus and Staphylococcus. The bacteria can enter the ear canal through an open wound, or if there is an infection in the throat or nose that spreads to the ear. In some cases, the infection can be caused by a foreign object that has been inserted into the ear, such as a cotton swab.
Diagnosis
If you have symptoms of a bacterial ear infection, it is important to see your doctor. Your doctor will examine your ear and may order a hearing test. They may also use a device called an otoscope to examine the inside of your ear. Other tests, such as a CT scan or MRI, may be needed to diagnose the infection.
Treatment
The treatment for a bacterial ear infection depends on the type and severity of the infection. Most ear infections are treated with antibiotics, which can be taken orally or applied directly to the ear. In some cases, a surgical procedure may be needed to remove the infected tissue.
Prevention
Ear infections can be prevented by keeping your ears clean and avoiding things that can damage the ear, such as using cotton swabs or inserting foreign objects into the ear. It is also important to treat any underlying illnesses, such as a cold or sinus infection. In some cases, a doctor may recommend using an ear drop to prevent infection.
