Background:
Ethmoidal arteries are at risk of accidental injury during endoscopic sinus surgery (ESS).
Aims/Objectives:
We aimed to examine the location of ethmoidal arteries in relation to ethmoid cells and the anterior skull base (ASB) in Japanese patients.
Material And Methods:
CT images of 100 sides of 50 patients were retrospectively reviewed. The location of anterior ethmoidal arteries (AEAs), middle ethmoidal arteries (MEAs) and posterior ethmoidal arteries (PEAs) in relation to ethmoidal cells and their distance from the ASB were evaluated.
Results:
AEAs and PEAs were present in all sides. 60% of AEAs and 9% of PEAs ran below the level of ASB. MEAs were present in 21 sides and ran below the ASB in 23.8% (5/21) of these sides. The incidence of AEAs running below the level of ASB was significantly higher in the sides with supraorbital ethmoid cells (SOECs) than in those without SOECs.
Conclusion And Significance:
This study revealed the position and the distance from ASB of AEAs, PEAs, and MEAs in relation to ethmoid cells in Japanese patients. In cases with SOECs, surgeons should be careful not to injure the AEAs running below the level of ASB. J. Med. Invest. 71 : 273-278, August, 2024.

01:27Cranial Bones: Lateral View
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...

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
