|June 3, 2009
Summary
Anatomical landmarks like the anterior ethmoidal foramen and sulcus are consistently visible on CT scans, aiding surgeons in locating the anterior ethmoidal artery (AEA) during sinus surgery.
Area of Science:
- Anatomy
- Radiology
- Otolaryngology
Background:
- The anterior ethmoidal artery (AEA) is crucial for frontal and ethmoid sinus surgeries.
- Computed tomography (CT) scans can identify landmarks to assist surgeons in locating the AEA.
Purpose of the Study:
- To identify landmarks of the AEA on the orbital medial wall and lateral wall of the olfactory fossa.
- To correlate supraorbital ethmoidal cells with the visualization of the anterior ethmoidal artery canal.
Main Methods:
- Retrospective review of 198 direct coronal paranasal sinuses CT scans.
- Data collected between August and December 2006.
Main Results:
- Supraorbital pneumatization observed in 35% of scans.
- Anterior ethmoidal artery canal visualized in 41% of scans.
- Anterior ethmoidal sulcus and foramen identified in 98% and 100% of scans, respectively.
Conclusions:
- Anterior ethmoidal foramen and sulcus are highly consistent anatomical landmarks.
- Supraorbital pneumatization correlates with the visualization of the AEA canal.

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
01:26Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
