Reconstruction of the anterior skull base following craniofacial resection

Reconstruction of the anterior skull base (ASB) following craniofacial resection must seal off the cranial cavity from the upper respiratory tract and provide structural support for the brain. The inferiorly based pericranial flap is strong, pliable, and well vascularized and is especially suited for reconstruction of small-to moderate-sized midline defects of the ASB. Surgical technique of pericranial flap reconstruction used in three cases is described. Indications for this flap and other types of reconstruction are discussed and compared. We believe pericranial flap reconstruction of the ASB is technically easy, cosmetically acceptable, and safe.
