Coronal approach

Coronal approach - incision

If a pericranial galeal flap is anticipated, the incision stays on top of the pericranium.
Otherwise, the incision goes to the bony surface. In the case that a pericranial flap may become necessary, it can be peeled off the underlying soft tissues at a later stage. It is, however, extremely difficult to dissect the pericranium from the subgaleal tissues once the flap has been raised.
