Varies...: The bone flap can be reattached using plates, sutures, or wires. For a nice description of brain surgery, see: http://www.Hopkinsmedicine.Org/neurology_neurosurgery/specialty_areas/brain_tumor/treatment/surgery/craniotomy.Html.

Varies regionally: At this time, in the U.S. The most common method of bone flap replacement is with small titanium bridging plates and screws that are placed circumferentially around the bone flap. Years ago, wires or sutures were also used. The plates are firmer and allow scar to bridge the gap between the bone flap and the cranium. Sometimes a bone matrix is placed in the gap to help "glue" the pieces together.
