Where is the infraorbital foramen located?
The infra-orbital foramen is located above the zygomatic process of the maxilla, about 2–3 cm from the median vertical line of the face. This orifice is more important than the supra-orbital foramen (Fig. 16.6).
What is the structure of the infraorbital foramen?
The infraorbital foramen, an opening into the floor of the eye socket, is the forward end of a canal through which passes the infraorbital branch of the maxillary nerve, the second division of the fifth cranial nerve.
Which bone belongs to the infraorbital foramen?
The infraorbital foramen is located in the maxillary bone. It is the anterior opening of the infraorbital canal, which is the anterior continuation of the infraorbital groove, which course through the floor of the orbit.
What does the infraorbital foramen articulate with?
portion of maxilla which articulates with the frontal bone of the cranium. This foramen is found in the maxillary bone, just inferior to the orbit. lower portion of the orbital surface on the Maxilla. The infraorbital groove is on this surface.
What is the role of infraorbital foramen?
In human anatomy, the infraorbital foramen is an opening in the maxillary bone of the skull located below the infraorbital margin of the orbit. It transmits the infraorbital artery and vein, and the infraorbital nerve, a branch of the maxillary nerve.
How do you palpate infraorbital foramen?
To palpate the infraorbital foramen, have the patient look straight ahead and imagine a line drawn vertically (sagittally) from the pupil down toward the inferior border of the infraorbital ridge. Keep the palpating finger in place over the inferior border on the infraorbital rim for the remaining steps.
What exits the infraorbital foramen?
The Maxillary Nerve (V2) It then passes through the orbit in the infraorbital canal, exits through the infraorbital foramen, and gives rise to three cutaneous branches: the zygomaticotemporal, zygomaticofacial, and infraorbital nerves.
Which artery reaches the face through the infraorbital foramen?
the maxillary artery
Infraorbital artery (IOA) is the branch of the maxillary artery. It appears in pterygopalatone fossa as a branch of third part of maxillary artery. It enters the orbit through inferior orbital fissure traveling anteriorly through infraorbital groove and infraorbital canal.
What does the infraorbital nerve innervate?
The infraorbital nerve supplies sensory innervation to the lower eyelid, the side of the nose, and the upper lip (see image below). Since the infraorbital nerve provides a considerably large area of sensory innervation, it is a prime candidate for a regional nerve block.
What is the function of the orbit?
The orbits are bony structures of the skull that house the globe, extraocular muscles, nerves, blood vessels, lacrimal apparatus, and adipose tissue. Each orbit protects the globe, while the supportive tissues allow the globe to move in three dimensions (horizontal, vertical, and torsional).
What does the infraorbital nerve block anesthetize?
Answer. An infraorbital nerve block, which branches from the maxillary nerve, anesthetizes the lower eyelid, upper cheek, part of the nose, and upper lip (see image below).
What passes through infraorbital groove?
The infraorbital groove (or sulcus) is located in the middle of the posterior part of the orbital surface of the maxilla. Its function is to act as the passage of the infraorbital artery, the infraorbital vein, and the infraorbital nerve.
Where is the infraorbital foramen located in the skull?
Anatomical terms of bone. In human anatomy, the infraorbital foramen is an opening in the maxillary bone of the skull located below the infraorbital margin of the orbit. It transmits the infraorbital artery and vein, and the infraorbital nerve, a branch of the maxillary nerve.
What is the opening of the infraorbital canal?
A bit rostrally to the facial tubercle, the infraorbital foramen, rostral opening of the infraorbital canal, opens on the lateral surface of the maxilla to let pass the infraorbital nerve, branch of the maxillary nerve, and the infraorbital artery, branch of the maxillary artery. There is no image containing this anatomical part yet.
How far is the infraorbital foramen from the midline?
The mean distance between the infraorbital foramen and supraorbital notch in males was 43.3 +/- 3.1 mm and in females was 42.2 +/- 2.4 mm. The average distance of the supraorbital notch from the midline was 26.5 +/- 3.5 mm in males and 26.3 +/- 3.3 mm in females.
