Sir,Bilateral extradural hematoma (EDH) is an uncommon consequence of closed head injury and the reported incidence ranges from 2 to 25%. Bilateral frontal EDH with coronal suture diastases is rarely reported. This report presents four cases of venous EDH where sinus is lacerated due to coronal suture diastases. All the patients had cranial scalp flap with craniotomy extending to either side of midline. The source of bleeding was found to be due to laceration of superior sagittal sinus.
