Burr hole cover for ventriculoperitoneal shunts and ventriculostomy: technical note.

In patients who have undergone intracranial procedures, bone gaps or burr holes often result in small but undesirable scalp or skin depressions. The authors designed a burr hole cover for hydrocephalus shunt system or external ventricular drainage, which is shaped to alleviate the deformity of the burr hole by filling the bone defect and allowing the passage of the ventricular catheter. The specifications of this device and its clinical application are described.
