Summary
Craniofacial morphology differs significantly in extremely preterm children compared to full-term controls. Preterm birth impacts facial development, affecting cranial base, jaw length, and incisor position.
Area of Science:
- Pediatric dentistry
- Craniofacial development
- Neonatal studies
Background:
- Premature birth can impact overall growth and development.
- Craniofacial morphology in preterm children requires further investigation.
Purpose of the Study:
- To compare the craniofacial morphology of very preterm and extremely preterm children with full-term controls.
- To test the hypothesis of no difference in craniofacial morphology between preterm and full-term born children.
Main Methods:
- Cephalometric analysis of lateral head radiographs from 36 very preterm, 36 extremely preterm, and 31 full-term children (aged 8-10 years).
- Inclusion of 15 angular and 11 linear cephalometric variables.
- Registration of height, weight, and head circumference.
Main Results:
- Extremely preterm children exhibited a shorter anterior cranial base and less convex skeletal profile.
- Both preterm groups showed significantly shorter maxillary length compared to full-term controls.
- Lower incisors were more retroclined and retruded in extremely preterm children; these children were also shorter with lower weight and smaller head circumference.
Conclusions:
- The null hypothesis was rejected, indicating significant craniofacial differences.
- Preterm birth is associated with distinct craniofacial morphology and growth deficits.
- Findings highlight the long-term effects of preterm birth on craniofacial development.

01:22Sutures of the Skull
13.3K
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...

01:29Bone Formation by Intramembranous Ossification
11.3K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

01:14Cranial Bones: Superior and Posterior View
8.0K
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,...

01:08Overview of the Skull
8.1K
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...

01:27Cranial Bones: Lateral View
7.4K
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...

01:24Prosopagnosia

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
