Objective:
To determine the dimension of the dorsum sellae (DS) in fetuses.
Methods:
Skull bases of 32 fetuses aged from 17 to 32 weeks were included in the work. The length of the DS at its superior border (DSL-SB) and the thickness of DS at its middle part (DST-ML) were measured. In addition, DS's height at its right lateral margin (DSH-RLB), at its left lateral margin (DSH-LLB), and at its middle part (DSH-ML) were measured.
Results:
DSL-SB, DSH-RLB, DSH-LLB, DSH-ML, and DST-ML were measured as 8.42±1.89, 2.67±0.68, 2.73±0.68, 2.48±0.75, and 2.00±0.50 mm, respectively. All parameters were statistically similar for both sexes ( P >0.05). All parameters increased with advancing gestational weeks ( P <0.001). Linear functions were calculated for DSL-SB (y=- 1.756 + 0.426 × age), DSH-RLB (y=- 1.072 + 0.156 × age), DSH-LLB (y=- 0.851 + 0.150 × age), DSH-ML (y=- 1.687 + 0.174 × age), and DST-ML (y=- 0.473 + 0.103 × age).
Conclusion:
In fetuses, DS size grows with age. The linear functions regarding DS-related parameters may be used to estimate its size.

01:22Sutures of the Skull
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...

01:27Cranial Bones: Lateral View
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...

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
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,...

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
