Summary
This study details a rare anatomical variation of the anterior ethmoidal artery (AEA) and ethmoidal foramen encountered during cadaveric dissection. Familiarity with these variations is crucial for surgeons to prevent serious complications.
Area of Science:
- Anatomy
- Surgical Anatomy
- Neuroanatomy
Background:
- The anterior ethmoidal artery (AEA) is a critical surgical landmark in anterior cranial fossa procedures.
- Anatomical variations of the AEA are well-documented and pose surgical risks.
- Injury to the AEA can result in severe hemorrhage and other complications.
Observation:
- This report presents a rare case of a variant accessory anterior ethmoidal artery and nerve.
- Variations in the ethmoidal foramen were also observed during cadaveric dissection.
- The ethmoidal foramen, a landmark for AEA identification, exhibits variable presentations.
Findings:
- A rare variant accessory anterior ethmoidal artery and nerve was identified.
- Observed variations in the ethmoidal foramen's presentation.
- Highlights the importance of recognizing anatomical anomalies in surgical planning.
Implications:
- Surgeons must be aware of potential AEA anatomical variations to mitigate risks.
- High-resolution computed tomography is recommended for difficult AEA identifications.
- Understanding these variations improves surgical safety in anterior cranial fossa procedures.

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...

01:14Cranial Nerves: Types Part I
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

01:22Cranial Nerves: Types Part II
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

01:03Olfactory Receptors: Location and Structure
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
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.
Encircling the heart, the coronary arteries form a ring-like structure before...

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...
