Aim: Define the average values of the cerebral ventricles size in ultrasonography transfontanellar in premature newborns and newborns at term in Benin environment.

Patients and Methods: This is a prospective cross-sectional study of analytical aiming. It took place over a period of 6 months, from May 1st to October 31st, 2012 at the National Hospital University Centre Koutoukou Hubert Maga in neonatal units and medical scanning. It focused on 100 newborns (subjects) including 50 premature newborns and 50 newborn at term. They all met the inclusion criteria. The cranial perimeter was also measured.

Results: The average cranial perimeter in premature newborn is 31.24 ± 6.23 cm while the one of the newborn at term is 33.34 ± 4.31 cm. In cerebral ultrasonography, the average value of the lateral ventricles in premature newborns is 2.43 ± 2.13 mm to the right side and 2.39 ± 2.03 mm to the left side while in newborns at term, the average value of the lateral ventricles is 1.81 ± 1.52 mm to the right side and 2.02 ± 1.33 mm to the left. As for The 3rd ventricle, it measures on average 3.62 ± 3.50 mm in premature newborns and 2.32 ± 2.56 mm in newborns at term.

Conclusion: there was a significant statistically difference between the ventricles size in premature newborns and newborns at term.
