Otitis Media: What You Need to Know

1. What Is Otitis Media?

Otitis media is inflammation, with or without infection, in the middle ear cavity. This is a general term that includes several forms, such as acute otitis media, otitis media with effusion, and chronic otitis media.

2. Where Is the Middle Ear Located?

The middle ear is a cavity located between the outer ear and the inner ear. It contains the ossicular chain, which transmits sound vibrations received from the external auditory canal through the tympanic membrane to the inner ear. Therefore, the middle ear plays a very important role in sound conduction as part of the hearing mechanism.

3. What Causes Otitis Media?

Otitis media results from a combination of infectious factors, including viral and bacterial infections, allergies, environmental factors such as exposure to dust and cigarette smoke, and the body’s immune status, including malnutrition, immunodeficiency disorders, and ciliary disorders.

4. What Are the Symptoms of Otitis Media?

• Ear pain
• Fever (more common in children)
• Ear discharge
• Swelling and tenderness behind the ear
• Tinnitus
• Hearing loss

5. Who Is More Likely to Develop Otitis Media?

• Otitis media can occur at any age, but it is particularly common in children aged 6 months to 2 years, especially acute otitis media.
• People who are frequently exposed to dust, smoke, or cigarette smoke.
• People who frequently experience upper respiratory tract infections, such as rhinosinusitis or adenoiditis.
• Patients with underlying conditions that cause immunosuppression, such as diabetes, HIV infection, or a history of chemotherapy or head and neck radiotherapy.

6. How Is Otitis Media Diagnosed?

• A thorough medical history is taken.
• The patient is examined using an otoscope or an ear endoscope.
• In some cases, such as complicated acute otitis media or suspected cholesteatoma, a temporal bone CT scan may be required for further evaluation.

7. What Are the Complications of Otitis Media?

• Tympanic membrane perforation, retraction, or adhesion
• Acute mastoiditis
• Acute petrous apicitis
• Facial nerve (CN VII) palsy
• Labyrinthitis
• Meningitis
• Brain abscess
• Lateral sinus thrombosis
• Tympanic membrane perforation and tympanic membrane adhesions caused by otitis media

8. How Is Otitis Media Treated?

8.1. Medical Treatment

Treatment focuses on addressing risk factors for otitis media, including adenoiditis, rhinosinusitis, and allergies.

Depending on the severity of otitis media, the physician may prescribe topical or systemic antibiotics, analgesics, anti-inflammatory medications, and antisecretory medications.

8.2. Surgical Treatment

Surgery is indicated in cases of acute otitis media complicated by mastoiditis with a subperiosteal abscess, epidural abscess, lateral sinus thrombosis, or brain abscess.

Surgery may also be indicated to manage complications or sequelae of otitis media, such as tympanic membrane perforation, middle ear effusion, or tympanic membrane adhesions, or to remove pathological tissue in cases of otitis media with cholesteatoma.

9. Prevention of Otitis Media

• Strengthen the body’s immune system.
• Maintain a healthy upper respiratory tract.
• Avoid exposure to dust, smoke, and cigarette smoke.
• For certain groups, particularly children, vaccination against pneumococcal disease and influenza is recommended.
• Control allergies.
