Description

The galeal frontalis is a type B fascial flap similar to temporoparietal flap, and is part of the occipitofrontalis fibromuscular layer of the scalp extending from the eyebrows to the nuchal line. The flap is usually harvested directly off a coronal flap just prior to its transfer to the anterior skull base (Fig. 12). It is placed over the anterior skull base through the inferior margin of the cranial bone flap. Length can be gained posteriorly by harvesting galea-pericranial tissue behind the coronal incision (extended galeal frontalis flap) prior to elevation of the coronal flap in the subperi-

Hydroxyapatite will effectively correct this deformity (right star) and prevent the wasted appearance in this area postoperatively.

cranial plane. Inclusion of the pericranium may enhance flap vascularity (30), especially over the cranial summit. The width of the flap is determined by the size of the defect (between 2 and 10 cm).
