Otitis externa is a medical term that describes an infection or pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation of the outer ear canal. This condition is often referred to as swimmer’s ear because it can be caused by water remaining in the ear after swimming. It can also occur due to various other factors.
Types of Otitis Externa
There are two main types of otitis externa:
- Acute Otitis Externa: This is the most common type and typically occurs suddenly. It causes pain, swelling, and redness in the ear canal.
- Chronic Otitis Externa: This type persists for an extended period and may cause long-term issues. It is often associated with underlying skin conditions.
Common Causes of Otitis Externa

- Ringing in the Ear (Tinnitus): Tinnitus can be a secondary symptom.
- Fluid Drainage: Fluid may leak from the ear, especially when the ear is manipulated.
- Hypersensitivity to Sound: Sounds may become uncomfortably loud.
Diagnostic Tests for Otitis Externa
- Clinical Examination: A healthcare provider will visually inspect the ear canal for signs of infection and inflammation.
- Swab for Culture: A sample may be taken from the ear canal to identify the specific bacteria or fungus causing the infection.
- Tympanometry: This test measures the movement of the eardrum in response to pressure changes and can assess middle ear function.
- Hearing Tests: Audiometry tests can determine the extent of hearing loss.
- Ear Canal pH: Testing the pH level in the ear can help identify certain types of infections.
- Imaging: In rare cases, imaging studies like CT scans or MRI scans may be used to assess the extent of infection.
- Blood Tests: In severe or recurrent cases, blood tests may be performed to check for underlying health conditions.
- Allergy Testing: If allergies are suspected, skin or blood tests may be done.
- Microscopy: A microscopic examination of ear discharge can reveal the presence of bacteria or fungi.
- X-rays: X-rays are used to rule out other conditions when the diagnosis is uncertain.
- Patch Testing: Patch testing may be used to identify allergies to certain substances.
- Ear Endoscopy: A tiny camera may be used to get a close look at the ear canal.
- Viral Swab: A swab can determine if a viral infection is responsible for the symptoms.
- Cultures for Atypical Organisms: In rare cases, special cultures are performed to detect unusual or atypical organisms.
