BASAL roof of the ethmoid cells or in the cribriform plate are frequently associated with an overlying tear in the dura mater which often leads to abscess of the brain or to meningitis. Reliable criteria of a torn dura overlying such a fracture following a closed injury of the head are: early meningitis, cerebrospinal rhinorrhea or intracranial aerocele. Signs suggestive of such a tear following a blow to the head are: complete anosmia in either nostril, a profuse nosebleed or a roentgenogram demonstrating a fracture in the anterior fossa. In cases of penetrating wounds of the skull, study of the external wounds, together with roentgenographic demonstration of the missile and its trailing bone fragments, will indicate whether there is a dural defect in the dangerous portion of the anterior fossa. The reasons for formal repair of the dura in this region have been presented by Calvert1 and Cairns.2 However, the
