The Cranioplasty Procedure
A cranioplasty is performed in a hospital setting with the patient under general anesthetic. A portion of the scalp will be shaved and a topical cleanser is applied to prevent infection. The surgeon then makes an incision in the skin to access the skull bones. If the existing bone is intact and undamaged, the surgeon can reshape and reposition it and use special discs as well as titanium plates and screws to secure it in place.
It is generally considered optimal to use the patient’s original bone if it remains functional. However, in cases where the bone has been badly damaged or removed, there are several options available. Prior to the surgery, it will be determined exactly what substance will be used to replace the bone. Depending on a number of factors, the surgeon may choose to graft a piece of bone that has been removed from the patient’s rib, skull or pelvis; use a bone substitute made from a synthetic material; or employ an acrylic insert that can be fitted into the defective area. All of these are attached to the nearby bones with titanium plates and screws.
Once the bone or grafting material has been properly affixed, the surgeon will close the scalp incision using either sutures or surgical staples.
