The cribriform fascia (also known as the fascia cribrosa, or Hesselbach's fascia) is the portion of the superficial layer of the
deep fascia of leg which extends between the

The cribriform fascia forms numerous openings to allow the passage of vessels and nerves, the most prominent of these being the
saphenous opening (saphenous hiatus) (which gives passage to the

Anatomy
Structure
An inferior aponeurotic thickening of the cribriform fascia - the falciform margin of sphenous opening - forms the inferior margin of the sapnenous opening, embracing the arch of the great saphenous vein.
Clinical significance
The cribriform fascia has been proposed for use in preventing
new vascularization when surgery is performed at the join between the
