Supraorbital foramen

Foramina supraorbitalia

The foramen supraorbitale ( Latin foramen , "opening"; supra "over"; orbis "circle") is a small bone canal in the frontal bone (os frontale), just above the orbital margin . It lies above the eyebrows , at the transition between the medial and middle third of the frontal bone, 2.3–2.9 cm lateral to the midline of the facial skull . The supraorbital nerve (eyeball nerve ), the first branch of the fifth cranial nerve (V ₁ ), the trigeminal nerve , ramus lateralis, and the arteria and vena supraorbitalis pass through it . It occurs in pairs, above the respective orbital margin.

  Facial skull anatomy

Supraorbital notch

Instead of a foramen, the anatomical deviation is merely a retraction, which is then called the supraorbital incisura .

Trigeminal pressure point

The supraorbital foramen is one of the trigeminal pressure points ( Valleix pressure points ) which react painfully to pressure when the stimulus threshold is reduced, which occurs symptomatically in trigeminal neuralgia . Trigeminal neuralgia is characterized by spontaneous or triggered, lightning-like shooting pain in the area of ​​one or more trigeminal branches, the first branch being rarely affected.

Conduction anesthesia

During surgical interventions on the soft facial tissues in the area of ​​the forehead, conduction anesthesia is applied to the supraorbital foramen.
