The pericranium is a thin connective tissue calvarial coating composed of two layers, one of which is periosteum and the other of which is loose areolar tissue. This autogenous calvarial coating can be used in selected facial cases as a free graft for coating, augmentation, or suspension techniques. Previous work has led to a better understanding of pericranial anatomy and histology, but it has focused primarily on the use of the material for free vascularized or rotational flaps.
Pericranium is often exposed during the course of facial surgeries such as coronal lifts and outer-table calvarial bone grafts. It can be easily harvested without significant defect to the donor area during these procedures, or it can be harvested as an independent procedure. The available surface area and volume of this graft material is larger than other scalp-related tissue, such as fascia from the temporal muscle.
