Frontobasilar blast injuries: access and treatment.

Blast injuries involving the frontobasilar region and orbit can present difficult evaluation and treatment challenges. This article presents the surgical treatment of four patients presenting with blast-type injuries involving the central periorbital region and anterior skull base. Three of these were the result of close-range gunshot wounds, and one was caused by an avulsive penetrating tree branch injury during a motor vehicle accident. All four patients underwent frontal craniotomy for exposure to repair significant intracranial injuries. Following intracranial repair of dural and brain injuries, anterior cranial fossa reconstruction was performed. In two of these patients, elective supraorbital osteotomies were performed to allow improved access to the posterior aspect of the anterior skull base. The healing period of all four patients has been without complications relative to the anterior fossa injuries.
