Osteomyelitis of the ear, often referred to as skull base osteomyelitis (SBO), is an infection of the bone or bone marrow around the ear and skull base. It's typically caused by bacteria, but sometimes can also be caused by fungus. This condition can also be referred to as necrotizing external otitis, or malignant otitis externa.
Understanding Skull Base Osteomyelitis
Skull base osteomyelitis (SBO) is a serious infection that needs medical attention. Here's a breakdown of key aspects:
What Happens
- The infection damages the bone and surrounding areas near the ear and the skull base. This can lead to significant complications if not treated promptly.
- It's a severe form of infection that affects the bony structures of the ear and skull base.
Causes
- Bacterial Infections: The most common cause of SBO is bacterial infections.
- Fungal Infections: In some cases, fungal infections can lead to osteomyelitis.
Alternative Names
- Necrotizing External Otitis: This name emphasizes the destruction of tissue due to the infection.
- Malignant Otitis Externa: This name suggests the severe and potentially dangerous nature of the condition.
Location
- The infection primarily affects the area around the ear and the base of the skull.
Why Is It Important?
Prompt diagnosis and treatment are essential because this infection can lead to further complications if not addressed properly.
