Abstract

Osteo-meningeal breaches of the anterior floor of the skull base are a solution of continuity between the meningeal and underneath bony structures. They can be primary or secondary, usually post traumatic or iatrogenic. The main clinical manifestations are rhino-liquorrhea and recurrent meningitis. Radiological investigations are highly contributory by exposing the defect and assessing the herniated content. Optimal treatment depends on the breach parameters and the consequent hernia. Surgery, when indicated, consists on the exposure of the defect and its clogging using different grafts. Endoscopic endonasal approach remains the most currently practiced regarding its aesthetic benefit and conclusive results.
