Noticeable defects can lead to issues with patient self-
esteem and social incompatibility. Primary recon-
struction is not always an option due to edema,
infection risk, or lack of vascular soft tissue coverage,
but it is a critical step in preventing exposure and
infection of the implant [48,49] . Patients often present
secondarily with gross deformation. Considering an
example of just one region-specific problem, defects
in the fronto-orbital region can also increase orbital

volume, which can in some instances lead to globe
malposition and eye dysfunction.

Materials
There have been varying degrees of success with
surgical reconstruction of cranial defects. The first
evidence of prosthetic corrections dates to the 16th
