Uncomplicated Wide Oblique Clivus Fracture, the First Case to be Included in the List of Classification; Report of the Case and Review of Literature

Sheno-occipital diastasis happens more frequently in children and is accompanied with neural and vascular injuries leading to a high rate of mortality. we present a rare type of clival fracture in a 21 years old man who could survive without any deficit even though the fracture extended widely from left asterion to the right orbit accompanied by widespread damage of the skull base air sinuses in 3d ct scan. to the best knowledge of the authors, neither this type of fracture, nor the clinical presentation, has been reported in relevant literature.
