By elevating the pericranium with the galeofrontalis tissue as a single unit, the most robust flap is obtained because the communicating vessels between the deep and superficial vessels are preserved.

The extensive pericranial flap provides a large apron of vascularized tissue for repair of the frontal sinus and anterior skull base. After subperiosteal dissection of the forehead and the supraorbital region, the reach of the flap increases again.

The anterior-based pericranial flap is very versatile and can be used in sealing of the nasal cavity in frontal sinus reconstruction, for closure, or obliteration of skull base defects, etc. The pericranial flap can also be extended to fill small volume defects.

The pericranial flap repair of anterior skull base defects has a 90% complication-free and 95% overall success rate. It is simple and extremely effective. Bone grafting has not been necessary in our experience.

2013年7月17日 · Pericranial flap is a composite flap involving the periosteum of the skull with subgaleal fascia. Their advantages include a convenient elevation for surgical procedures, versatility, and a lack of functional and morphological complications at donor sites.

2021年2月18日 · When skull base reconstruction using a nasoseptal flap is not an option, the vascularized pericranial flap provides an excellent alternative reconstructive option due to its local availability, robust vascular supply, and excellent reliability.

The pericranial flap (PCF) is the most versatile alternative to the NSF and has the potential for the largest area of coverage. Its pedicle is based upon the supraorbital and supratrochlear arteries, and it was commonly used for skull base reconstruction in the era prior to the widespread use of endoscopic resection [ 5 ].
