What does supratrochlear artery supply?
Arising from the ophthalmic branch of the internal carotid system, the supratrochlear artery supplies the midline forehead flap. This is probably the oldest flap in history and still has a place today. The artery runs over the medial one-third of the supraorbital rim to supply the midline forehead up to the vertex.
What is supratrochlear artery?
The supratrochlear artery (STA) is a terminal branch of the ophthalmic artery (OA) which in turn is the first intracranial branch of the internal carotid artery (ICA) [1]. After exiting the orbit, the vessel travels vertically, ascending to the forehead, approximately 2 cm from the midline [2].
What is the structure of the supratrochlear?
Structure. The supratrochlear nerve is a branch of the frontal nerve, itself a branch of the ophthalmic nerve (CN V1) from the trigeminal nerve (CN V). It is smaller than the supraorbital nerve from the frontal nerve. It branches midway between the base and apex of the orbit.
Where does the supraorbital artery arise?
The supraorbital artery stems from the ophthalmic artery in the superomedial aspect of the orbit. It leaves the orbit through the supraorbital groove and emerges onto the forehead. It terminates by dividing into two terminal branches; superficial and deep.
Where is supratrochlear artery?
forehead
The supratrochlear artery exits the orbit at the frontal (supratrochlear) notch, located on the medial aspect of the supraorbital margin. Upon emerging onto the forehead it provides small branches for the periosteum, muscles and skin of the forehead region.
Where does the Supratrochlear vein drain?
The supratrochlear vein drains a venous plexus on the anterior forehead and scalp 1,2. It is a tributary of the angular vein along with the supraorbital vein 3.
Where is the supratrochlear lymph node located?
Epitrochlear or supratrochlear nodes are located superficial to the deep fascia of the arm and medial to the basilic vein and proximal to the medial epicondyle.
What is the function of supratrochlear?
The supratrochlear nerve (internal frontal) runs towards the inner corner of the eye. It gives off filaments supplying the frontal periosteum, the skin of the lower part of the forehead, and the upper eyelid and its conjunctiva.
Where is the supratrochlear node?
Where is the supraorbital vein?
The supraorbital vein (v. supraorbitalis) begins on the forehead where it communicates with the frontal branch of the superficial temporal vein. It runs downward superficial to the Frontalis muscle, and joins the frontal vein at the medial angle of the orbit to form the angular vein.
How deep is the supratrochlear artery?
The mean depth of the supratrochlear artery was 3.34 [0.6] mm at rest, whereas the depth of the supraorbital artery was 3.54 [0.8] mm.
What is the function of the supratrochlear lymph nodes?
a small group of superficial lymph nodes proximal to the medial epicondyle of the humerus; they drain the forearm and send efferent vessels to the deep lymphatic channels of the arm.

What is Supratrochlear lymph nodes?
a small group of superficial lymph nodes proximal to the medial epicondyle of the humerus; they drain the forearm and send efferent vessels to the deep lymphatic channels of the arm. Synonym(s): nodi lymphoidei supratrochleares.
