In anatomy, the saphenous opening (saphenous hiatus) is an oval opening in the superomedial part of the fascia lata of the thigh, lies 3–4 cm inferolateral to the pubic tubercle. It is about 3 cm long and 1.5 cm wide.

Description

•Above, lateral and below → sharp border called falciform margin. It is thickened by the Allan Burns' ligament. •Covered by a thin perforated part of the superficial fascia called the cribriform fascia (pierced by the great saphenous vein, the 3 superficial branches of the femoral A., and lymphatics).

It transmits the great saphenous vein and other smaller vessels (like superficial epigastric artery and superficial external pudendal artery), as well as the femoral branch of the genitofemoral nerve.

The cribriform fascia, which is pierced by the structures passing through the opening, closes the aperture and must be removed to expose it.

Surgery is still the procedure of choice in treatment of advanced vulvar cancer. Radical vulvar surgery is often associated with severe vulvar and inguinal skin and fat-tissue deficits resulting from wide "butterfly" shape resection. Primary closure of large vulvar and inguinal defects is hampered b
