ABSTRACT
Autogenous calvarial bone grafts have been widely used in craniofacial reconstruction
following trauma, congenital anomalies, and head and neck tumors. In cases of late
restoration of a collapsed cranial vault, an extradural dead space is occasionally
observed which might cause infection and grafted bone absorption. The combined use
of a split calvarial bone graft and an omental flap has been an effective technique
for treating complicated cranial defects. The omental flap eliminates the extradural
dead space between the grafted calvarial bone and the scarred dura, and provides an
acceptable vascular bed for grafted bone. The authors report this technique for complex
cranioplasties in two cases, with good cosmetic results.
