Frontal Sinus Cranialization Using the Pericranial Flap: An Added Layer of Protection

Abstract

The pericranial flap is easily harvested and versatile. Using this vascularized tissue during cranialization affords added protection by providing an extra barrier between the intracranial cavity and the frontal bone and sinonasal tract. This technique is inexpensive, safe, and effective and should be considered when cranialization of the frontal sinus is performed.
