Insights
This study provides crucial thickness data for pediatric occipital bones, essential for guiding occipitocervical fusion procedures in children. Findings highlight age-related variations and regional differences in bone thickness.
Area of Science:
- Pediatric Neurosurgery
- Craniofacial Anatomy
- Medical Imaging
Background:
- Limited data exists on pediatric occipital bone thickness across age groups.
- Understanding these anatomical variations is critical for surgical planning.
Purpose of the Study:
- To establish reference data for immature occipital bone thicknesses.
- To inform and improve pediatric occipitocervical fusion techniques.
Main Methods:
- Computed tomographic (CT)-based morphometric analysis.
- 80 pediatric patients categorized into 4 age groups.
- Philips Brilliance 256 iCT scan utilized for imaging.
Main Results:
- Mean occipital bone thickness varies significantly between age groups.
- Median and paramedian regions are consistently thicker than lateral regions.
- External occipital protuberance is typically the thickest point; no significant sex-based differences noted except in one group.
Conclusions:
- Provides essential anatomical insights into pediatric occiputs.
- Preoperative CT evaluation is vital to minimize risks associated with occipitocervical fusion.
Study Design:
This study is a computed tomographic-based morphometric analysis of the pediatric occipital bones as related to pediatric occipitocervical fusion.
Objective:
To quantify reference data concerning the thicknesses of the immature occipital bones to guide the pediatric occipitocervical fusion.
Summary Of Background Data:
To the best of our knowledge, no published study has provided insight into the thicknesses of pediatric occiputs with different age groups.
Methods:
80 pediatric patients were divided into 4 age groups, and their occiputs were studied on Philips Brilliance 256 iCT scan.
Results:
The mean thickness ± standard deviations of the pediatric occipital bones with different age groups is shown. The median and the paramedian regions are always thicker than the more lateral regions at each age group and the thickest point in the occiputs is mostly at the external occipital protuberance. The mean thickness of occiputs showed an obvious significant difference between each 2 age groups and no significant difference between male and female in different age groups except the group 4.
Conclusion:
Our investigation provides insight into the anatomy of occiputs in pediatric population and preoperative CT evaluation must be required to further decrease the risk of occipitocervical fusion.

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,...
