Figure 3: Coronal computed tomography bone scan of skull base for week 8 ossification pattern revealed that orbital plates were completely ossified with thick medial end there was an extension of that plates over the lateral ethmoidal cells. Roof of ethmoid complex was ossified partially with very small gap between the ossified medial and lateral extensions. Vomer was ossified but did not meet perpendicular plate of the ethmoid in posterior nasal septum. Crista galli not ossified and not fused with the ethmoidal labyrinths. Cribriform plate was ossified. Ethmoidal cells were developed no extension above plane of the cribriform
