An Anatomical Investigation Regarding the Parietal Foramen in 174 Adult Parietal Bones
View abstract on PubMed
Summary
This summary is machine-generated.The parietal foramen (PF) was present in 64.3% of 174 adult human parietal bones, with most being single, circular, and posteroanteriorly oriented. These anatomical findings aid in surgical procedures near the PF.
Area Of Science
- Anatomy
- Anthropology
- Surgical Anatomy
Background
- The parietal foramen (PF) is an anatomical landmark with clinical relevance.
- Understanding its variations is crucial for surgical interventions and anthropological studies.
Purpose Of The Study
- To investigate the anatomical features of the parietal foramen (PF).
- To document the frequency, morphology, and morphometry of the PF in adult human parietal bones.
Main Methods
- Examination of 174 dry adult human parietal bones.
- Recording frequency, shape, and direction of the PF.
- Measuring diameter of the PF (DPF), distance to sagittal suture (DSS), distance to occipital angle (DPO), and length of sagittal suture (LSS).
- Calculating the LSS/DPO ratio for topography of the PF (TPF).
Main Results
- Parietal foramina (PF) were present in 64.3% of bones.
- Most PFs were single (90.7%), circular (94.1%), and oriented posteroanteriorly.
- Mean measurements: DPF (1.7±0.6 mm), DSS (6.81±3.40 mm), DPO (33.81±12.43 mm), LSS (108.94±6.91 mm).
- TPF ratio was approximately 3:1.
Conclusions
- The anatomical data on parietal foramen (PF) variations are vital for surgical planning.
- Findings can help reduce complications during procedures involving the PF and surrounding structures.

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,...
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...
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.
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...
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
