Opening the skull: This is a surgical procedure that opens a window in the skull to access the brain and its blood vessels and coverings. The bone is usually put back at the end of the procedure.

Brain Surgery: Craniotomy refers to the procedure where neurosurgeons open the cranium to access the brain. This may be done for disorders like head trauma, brain tumors, or stroke. The actual procedure in brief involves drilling a few burr holes or access holes. The dura is stripped from the bone, a special "jigsaw puzzle" like drill is used to connect the holes and the bone removed. It is replaced later.
