In what scenario would a craniectomy be indicated?

A craniectomy is indicated in the scenario of severe brain swelling. This procedure involves the surgical removal of a portion of the skull to relieve pressure on the brain. When the brain becomes swollen due to injury, trauma, or other conditions, this swelling can lead to increased intracranial pressure, which can be life-threatening. By performing a craniectomy, the surgeon creates more space for the swollen brain, thereby reducing pressure and potentially preventing further damage.

In contrast, chronic sinusitis typically does not necessitate a craniectomy, as it affects the sinuses rather than the intracranial structures. Skull fracture repair targets a different issue and involves restoring structural integrity rather than addressing brain swelling. Similarly, a minor cerebral contusion would not usually require such an invasive procedure; it can often be managed with monitoring and conservative treatment unless complications like significant swelling occur.
