Depressed skull fractures result in the bone of the skull vault being folded (depressed) inward into the cerebral parenchyma. It is usually the result of a high energy impact to the skull.
These mostly (~75%) occur in the frontoparietal region 3.
There are a number of associated injuries with depressed skull fractures 1,2:
- extradural hematoma
- subdural hematoma
- cerebral contusion
- subarachnoid hemorrhage
- CSF leak
Rarely undertaken, especially outside of the pediatric population. The fracture is identified due to the projection of dense bone over the skull.
The modality of choice in head trauma. The fracture is shown in detail along with any associated injuries.
Treatment and prognosis
There are a number of indications for operative management, these include 2-4:
- dural breach, increased risk if >5 mm depression from inner table
- depression >5-10 mm
- significant intracranial hemorrhage
- frontal sinus involvement
- significant wound contamination or cosmetic deformity
Depressed skull fracture are associated with higher rates of infection (~10%), seizure (~15%), neurological deficits, and death 3.
