Summary
Skull base osteomyelitis, a complication of malignant otitis externa, can spread extensively. This case shows severe skull base and cervical spine involvement, even contralaterally, over three years.
Area of Science:
- Radiology
- Infectious Diseases
- Otolaryngology
Background:
- Skull base osteomyelitis is a severe complication of malignant otitis externa.
- Diagnosis typically relies on clinical, microbiological, and radiological assessments.
Observation:
- A 76-year-old man presented with right-sided malignant otitis externa involving otomastoid structures and the temporal bone.
- Over three years, skull base osteomyelitis progressed despite antibiotic therapy.
Findings:
- The infection spread to involve the entire skull base, including the contralateral petrous temporal bone.
- Cervical vertebral processes were also affected, demonstrating an exceptional extent of disease.
Implications:
- This case highlights the potential for aggressive progression of malignant otitis externa and skull base osteomyelitis.
- It underscores the importance of comprehensive imaging and long-term monitoring for extensive infections.

01:22Sutures of the Skull
10.3K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:08Overview of the Skull
7.6K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:55Secondary Active Transport
137.5K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

2.0K
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.
