A Skull fracture is a break in one or more of the eight bones that form the cranial portion of the skull, usually occurring as a result of blunt force trauma. If the force of the impact is excessive, the bone may fracture at or near the site of the impact and cause damage to the underlying structures within the skull such as the brain.

Types of Skull Fractures

There are four major types of skull fractures, which are classified based on the appearance of the fracture and the pattern of the break:

1. Linear skull fracture: This is the most common type of skull fracture. It involves a break in the bone but does not move the bone.
2. Depressed skull fracture: This type of fracture may be seen with or without a cut in the scalp. In this fracture, part of the skull is actually sunken in from the trauma.
3. Diastatic skull fracture: These are fractures that occur along the suture lines in the skull. The force of the blow may widen the sutures and can be seen most often in newborns and older infants.
4. Basilar skull fracture': This is the most serious type of skull fracture, and involves a break in the bone at the base of the skull. Patients with this type of fracture frequently have bruises around their eyes and a bruise behind their ear.

Symptoms

Symptoms of a skull fracture can include:

• Headache
• Nausea
• Vomiting
• Dizziness
• Confusion
• Loss of consciousness
• Bleeding from wound, ears, nose, or around eyes

Diagnosis

Diagnosis of a skull fracture typically involves a physical examination and imaging tests. The most common imaging test is a CT scan, which can reveal fractures and also show evidence of injury to the brain, bleeding, or blood clots.

Treatment

Treatment for a skull fracture depends on the type of fracture and the severity of the injury. It may include:

• Observation
• Pain management
• Surgery
• Physical therapy
• Occupational therapy

• Traumatic brain injury
• Concussion
• Cerebral contusion
• Cerebral edema
