Objective:
The aim of this study was to characterize the normal ultrasonographic growth of the fetal superior sinus sagittalis (SSS) throughout gestation.
Patients And Methods:
In a prospective cross-sectional study, measurements of the fetal sinus sagittalis were obtained in patients undergoing elective fetal anatomical surveys or fetal growth scan at between 16.6 and 34.7 weeks of gestation. Special attention was given to the SSS of the fetal brain. On the coronal plane, the SSS may be easily identified immediately below the frontal bone, and anterior to the fetal head parenchyma.
Results:
206 fetuses were scanned. A regression line of the SSS was created throughout gestation and a first-degree correlation was found between gestational age (GA) and the SSS height (r = 0.418; p < 0.0001; SSS = -0.015 + 0.0178 × GA). Normal values were established for different gestational weeks.
Conclusion:
We provide ultrasonographic dimensions of the fetal SSS across pregnancy. This data potentially allows for prenatal diagnosis of abnormal appearance of the SSS.

Cranial 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,...
Cranial 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...
