Cranial Bones: Lateral View

Cranial 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...

Area of Science:

Anatomy
Craniofacial Anatomy
Surgical Anatomy

Background:

The pterion, a key cranial junction, exhibits anatomical variability in newborns due to incomplete ossification.
Understanding pterional localization is crucial for neurosurgical procedures.

Purpose of the Study:

To delineate the topographic anatomy of the pterion in neonatal cadavers.
To investigate the variability in pterion localization on neonatal craniums.

Main Methods:

Analysis of 35 term neonatal cadaver specimens.
Measurement of distances from the pterion to critical cranial landmarks.
Utilized a scale diagram to define pterional area localization.

Main Results:

The pterion was predominantly located in regions c, d, e, f (length) and 2, 3, 4, 5 (width).
Region e4 represented the most frequent pterion localization (24.28%).
Pterion localization was not observed in regions a, b, g, h, and squares 1, 6.

Conclusions:

Provides detailed topographic data on pterion localization in neonates.
Aids clinicians in surgical planning and treatment for improved surgical outcomes.
Highlights the importance of considering variable pterional anatomy in pediatric neurosurgery.
