Chronic Mastoiditis: Symptoms and Treatment
Chronic mastoiditis is a persistent inflammation or infection of the mastoid bone, located just behind the ear, that can severely impact an individual's quality of life if not accurately diagnosed and adequately treated. This condition can arise as a complication from an inadequately treated acute middle ear infection or otitis media.
Chronic mastoiditis refers to a long-standing infection or inflammation of the mastoid bone. The mastoid bone is part of the temporal bone of the skull and contains air cells that help with drainage of the middle ear. When these air cells become infected or inflamed, chronic mastoiditis can occur.
Causes of Chronic Mastoiditis
The causes of chronic mastoiditis are often linked to recurrent or untreated acute otitis media. When the infection in the middle ear spreads to the mastoid bone, it can lead to mastoiditis. Factors contributing to this condition include:
- Recurrent ear infections: Persistent ear infections that are not adequately treated can spread to the mastoid bone.
- Obstruction of the Eustachian tube: This tube connects the middle ear to the back of the throat and helps equalize pressure. Blockage can lead to fluid build-up, creating an environment for infection.
- Compromised immune system: Individuals with weakened immune systems are more susceptible to infections, including those affecting the mastoid bone.

Recognizing the symptoms of chronic mastoiditis is essential for early diagnosis and treatment. The symptoms can vary but often include:
- Persistent ear discharge: A continuous and sometimes foul-smelling discharge from the ear is a common symptom.
- Hearing loss: Progressive hearing loss in the affected ear can occur due to the infection's impact on the ear's structures.
- Pain and swelling: Pain and swelling behind the ear, sometimes extending to the neck, are typical signs.
- Fever: Chronic mastoiditis may present with low-grade fever due to ongoing infection.
- Headache: Persistent headaches can accompany the condition, mainly if the infection spreads.
Complications of Chronic Mastoiditis
If left untreated, chronic mastoiditis can lead to severe complications. These include:
- Meningitis: The infection can spread to the meninges, the protective membranes covering the brain and spinal cord, leading to meningitis.
- Brain abscess: An abscess may form in the brain if the infection spreads, posing a life-threatening condition.
- Facial nerve palsy: The facial nerve, which runs through the middle ear, can be affected, leading to facial paralysis.
- Hearing loss: Chronic infection can cause permanent damage to the structures of the ear, resulting in irreversible hearing loss.
Diagnosing Chronic Mastoiditis
Early and accurate diagnosis of chronic mastoiditis is critical for effective treatment. Diagnosis typically involves a combination of clinical examination and diagnostic tests.
Clinical Examination
The first step is a thorough clinical examination by an otolaryngologist (ENT specialist). The doctor will examine the ear using an otoscope to look for signs of infection or inflammation. They will also assess the patient's medical history, including any recurrent ear infections.
Diagnostic Tests
Several diagnostic tests can aid in confirming chronic mastoiditis:
- Imaging studies: CT scans or MRI scans of the mastoid bone can reveal the extent of the infection and any structural damage.
- Audiometry: Hearing tests can determine the degree of hearing loss and help in assessing the impact of the infection.
- Culture and sensitivity tests: These tests involve taking a sample of the ear discharge to identify the causative organism and determine the most effective antibiotics.

Book an AppointmentTreatment of Chronic Mastoiditis
The treatment of chronic mastoiditis aims to eliminate the infection, alleviate symptoms, and prevent complications. A multi-faceted approach is often necessary.
Medical Treatment
- Antibiotics: Long-term antibiotic therapy is the cornerstone of treatment. To ensure effectiveness, the choice of antibiotics is usually guided by culture and sensitivity tests.
- Ear drops: Antibiotic ear drops may be prescribed to target the infection directly within the ear.
- Pain management: Analgesics and anti-inflammatory medications can help manage pain and reduce inflammation.
Surgical Treatment
In cases where medical treatment fails, or complications arise, surgical intervention may be necessary.
- Myringotomy: This procedure involves creating a small incision in the eardrum to drain fluid and relieve pressure.
- Mastoidectomy: In severe cases, surgical removal of the infected mastoid bone may be required. This procedure aims to eradicate the infection and prevent its spread to adjacent structures.
- Tympanoplasty: Reconstruction of the eardrum and middle ear structures may be necessary to restore hearing and prevent recurrent infections.
Preventing Chronic Mastoiditis
Prevention of chronic mastoiditis essentially involves managing and treating acute otitis media promptly and effectively. Key preventive measures include:
- Timely treatment of ear infections: Ensuring that ear infections are adequately treated with the appropriate antibiotics can prevent the progression of chronic mastoiditis.
- Regular medical check-ups: Regular visits to an ENT specialist can help in the early detection and management of recurrent ear infections.
Maintaining ear hygiene: Keeping the ears clean and dry, especially after swimming, can reduce the risk of infections.
