Infection in the skull, also known as osteomyelitis of the skull, can arise from several causes. These include direct injury, spread from nearby infections, or surgical complications.
Causes of Skull Infections
Skull infections can occur due to various factors, which are often interconnected.
-
Surgery: Surgical procedures involving the skull can sometimes introduce bacteria, leading to infection.
-
Scalp Wounds: Open wounds on the scalp provide a direct pathway for bacteria to enter the bone.
-
Sinus Infections: Infections in the sinuses, particularly the frontal sinus, can spread to the skull. Pott's puffy tumor, for instance, usually develops from a frontal sinus infection.
-
Ear Infections: Similarly, ear infections can, in some cases, extend and infect the nearby skull bone.
-
Trauma: Injuries to the head can cause breaks in the skin and bone, allowing bacteria to enter.
Pott's Puffy Tumor
Pott's puffy tumor is a specific type of skull infection, often characterized by swelling of the forehead. As noted, it commonly arises from:
- Frontal Sinus Infections: Untreated or severe frontal sinusitis can erode through the sinus walls and infect the skull.
- Trauma: Head trauma that damages the frontal sinus area may also lead to this condition.
Factors Contributing to Skull Infections
Several factors can increase the risk of developing a skull infection. These include:
- Weakened Immune System
- Poor Hygiene
- Underlying Health Conditions (e.g., diabetes)
