Successful Treatment of Full Thickness Frontal Skull Bone Defect With Dermal Fat Grafting and Artificial Bone Grafts.

Rigid reconstruction for frontal bone defects not only improves function, but also approximates more normal appearance. However, in cases involving dural scar contractures, a concave deformation remains when rigid reconstruction is performed without compensating for dead space created by swelling of the brain. This study involved 4 cases in which a 2-stage reconstruction procedure was used to first eliminate dead space by grafting dermal fat, and subsequently carry out rigid reconstruction to achieve a natural forehead configuration. This method is advantageous and considered to be effective in allowing dead space to be easily filled with minimal invasiveness for concave deformations of the dura mater with bone defects. Furthermore, the risk of artificial bone exposure is reduced by adding the dermal component of dermal fat, which is grafted to thinned frontal skin.
