disclosed herein are patient - specific craniofacial implants structured for filling bone voids in the cranium as well as for simultaneously providing soft tissue reconstruction and / or augmentation for improved aesthetic symmetry and appearance . pterional voids or defects generally result from a chromic skull deformity along with a compromised temporalis muscle or soft tissue distortion from previous surgery . when muscle atrophy occurs in the pterion , temporal hollowing generally results where there would be soft tissue but for the atrophy . the patient - specific temporal implants herein are configured to have an augmented region adjacent the temporal region of the cranium in order to account for and correct any such temporal hollowing .
