The anterior ethmoidal artery is a branch of the ophthalmic artery in the orbit. [1] It exits the orbit through the anterior ethmoidal foramen alongside the anterior ethmoidal nerve. It contributes blood supply to the ethmoid sinuses, frontal sinuses, the dura mater, lateral nasal wall, and nasal septum. It issues a meningeal branch, and nasal ...

2024年8月25日 · The anterior ethmoidal artery is a branch of the ophthalmic artery. It supplies the anterior and middle ethmoidal sinuses, frontal sinus, the lateral nasal wall and the nasal septum (see nasal cavity).

The anterior ethmoidal artery (AEA) runs through the roof of anterior ethmoidal sinuses traveling from the orbit to the anterior cranial fossa. AEA is a major anatomical landmark that is vulnerable to accidental injury during surgery on the anterior ethmoidal sinus and skull base.

Origin: Ophthalmic artery. Course: Passes within the anterior ethmoidal canal and enters the anterior cranial fossa via the anterior ethmoidal foramen. Branches: Anterior meningeal, anterior septal, and anterior lateral nasal branches. Supplied Structures: Anterior ethmoidal cells, frontal sinus, dura mater, and nose.

Septal system (purple) here is mainly supplied by the ophthalmic via anterior ethmoidal (red) artery. When particularly big, ethmoidal supply can contribute to failure of epistaxis embo. In this case, the ethmoidals must be surgically closed

2024年3月15日 · The anterior ethmoidal artery (AEA) arises from the ophthalmic artery distal to the point of origin of the posterior ethmoidal artery. It exits the medial orbital wall through the anterior ethmoidal foramen, subsequently crossing the anterior ethmoid air cells through the anterior ethmoidal canal to the anterior cranial fossa ( Figure 1 ).

2025年1月24日 · The anterior ethmoidal artery is a branch of the ophthalmic artery that supplies blood to the anterior and middle ethmoidal air cells, nasal cavity, and parts of the dura mater in the anterior cranial fossa. It plays an important role in the vascularization of the nasal structures and surrounding tissues.

The anterior ethmoid artery, a branch of the ophthalmic artery off of the internal carotid, courses anteromedially as it leaves the orbit heading toward the intracranial area. Typically, the artery is housed in a bony canal as it courses along the skull base.

The anterior ethmoidal artery is a branch of the ophtlamic artery. It accompanies the nasociliary nerve through the anterior ethmoidal canal, supplies the anterior and middle ethmoidal cells and frontal sinus, and, entering the cranium, gives off a meningeal branch to the dura mater, and nasal branches; these latter descend into the nasal ...

2009年1月1日 · The anterior ethmoidal artery (AEA) is an important point for frontal and ethmoid sinuses surgery. CT scans can identify landmarks to help the surgeon find the AEA.
