Summary
This study analyzed anatomical variations in the foramen ovale, finding significant differences in size and shape. These variations are crucial for surgical and diagnostic procedures involving the foramen ovale.
Area of Science:
- Anatomy
- Morphology
- Surgical Anatomy
Background:
- The foramen ovale is critical for various neurosurgical and diagnostic procedures.
- Understanding its anatomical variations is essential for successful interventions.
Purpose of the Study:
- To investigate and document the anatomical variations in the dimensions, appearance, and number of the foramen ovale.
- To provide data relevant to surgical and diagnostic applications.
Main Methods:
- A study was conducted on 35 dried human skulls.
- Measurements of foramen ovale length and width were taken.
- Variations in shape, number, and presence of bony landmarks were recorded.
Main Results:
- Mean dimensions were recorded for right and left sides.
- The foramen ovale exhibited various shapes including oval, almond, round, and slit-like.
- Bony landmarks such as spines, tubercles, spurs, and plates were observed on the margins.
- Overall, 24.2% of the foramen ovale showed variations.
Conclusions:
- Anatomical variations in the foramen ovale are likely due to developmental factors.
- Awareness of these variations is vital for clinicians performing procedures related to the foramen ovale.

01:26Bone Markings
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
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,...

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...

01:18Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
01:19Cranial Nerves: Overview and Anatomy
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...
01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
