A fracture can develop in one or multiple bones of the skull due to a head injury. In the majority of skull fractures, no complications arise. Yet, in cases of significant trauma, the fractured bones could shift from their original positions. When this occurs, fragments of bone might damage blood vessels within the meninges—the protective membranes enveloping the brain—or, although rarely, even tear these membranes. This can lead to bleeding and, in certain instances, cause damage to the brain.
A straightforward skull fracture typically mends on its own. Yet, if there is any harm to brain structures, the intervention of neurosurgery is frequently necessary.
