non-penetrating head injuries associated with skull base fractures can lead to the development of pneumocephalus upon airs ingress, which leads its course in the subarachnoid space. intracerebral air accumulation is rare and ensuses when a paranasal sinus fracture is associated with a ensues when a paranasal sinus fracture is associated with a nearby parenchymal contusion. a 25-year old man is ...

several lesions (inflammatory, neoplastic and congenital) can involve in the skull base. the role of imaging is to detect the location and extension of lesion, determine mass and mass like lesions, differentiate benign from malignant tumors, detect invasion to adjacent structures and make decision in surgical planning. skull base divides to anterior, middle and posterior cranial fossa and some ...

The skull base is one of the most complex anatomical regions and forms the floor of the cranial cavity. Skull base surgery involves open, microscopic, and endoscopic approaches to the anterior, middle, or posterior cranial fossa. A multispecialty team approach is essential in treating patients with skull base lesions. Traditionally, rhinologists are involved in providing access to anterior skul...

BACKGROUND AND PURPOSE Interpretation of CT of the anterior skull base in children depends on knowledge of the pattern and chronology of ossification. The purpose of this study was to ascertain the age at which the anterior cranial fossa is fully ossified as assessed on CT examinations. MATERIALS AND METHODS This was a retrospective review of 127 CT examinations of children ranging from 1 day...

A modifi ed subcranial approach based upon the procedure fi rst described by Joram Raveh is a viable alternative to standard craniofacial resection for treating pathology of the anterior skull base. It is basically an extradural approach providing wide exposure to the anterior skull base with minimal brain retraction; thus decreasing signifi cantly the morbidity. We present here two cases of a ...
