ABSTRACT We report the morbidity and mortality associated with fractures of the clivus and discuss management approaches specific to this unique diagnostic entity.
We performed a boolean search of our electronic medical record database to identify patients with fractures of the clivus that were diagnosed using computed tomography of the head. A retrospective imaging and chart analysis was completed to further characterize the fractures and to analyze outcomes.
Between January 1999 and December 2007, 41 patients were identified with fractures of the clivus. We found a 0.21% overall incidence among all head-injured patients presenting to our institution and a 2.3% incidence among those patients with a cranial fracture. Ten of 41 patients (24.4%) died, and neurological and vascular complications associated with central cranial base fractures were observed in 19 of 41 patients (46%). Furthermore, associated cranial fractures remote from the central cranial base and associated intracranial hemorrhages were observed in 40 of 41 (97.6%) and 33 of 41 (80.5%) patients, respectively. In terms of outcomes, 26 of 41 patients (63.5%) had a Glasgow Coma Scale score of 12 or greater at the time of discharge from the hospital.
We demonstrate a lower than previously reported mortality rate in patients with clival fractures. Nevertheless, as a result of location, fractures of the clivus were frequently associated with a high rate of complications and neurological sequelae.

    ABSTRACT: Basilar skull fractures are a relatively frequent occurrence in significant head trauma, and their detection is important, as even linear nondisplaced fractures can be associated with critical complications. The management of skull base fractures depends on the location and extent of these associated complications. This article reviews skull base anatomy; morphology of the common fracture patterns within the anterior, central, and posterior skull base; associated complications; imaging findings; and possible pitfalls in imaging of skull base trauma.

    ABSTRACT: Fractures of the clivus and traumatic diastases of the clival synchondroses are rare in the pediatric population. The incidence, outcome, and biomechanics associated with these fractures have been difficult to ascertain secondary to the lack of literature pertaining to their occurrence. A Boolean search of the electronic medical record database at the Children's Hospital of Pittsburgh, University of Pittsburgh Medical Center, was performed to identify patients with fractures of the clivus that were diagnosed using CT of the head. A retrospective review of the chart and radiographic imaging was then performed to assess data regarding patient demographics, mechanism of injury, and skull and brain parenchymal injuries, as well as outcomes. Between May 2002 and November 2007, 16 patients with fractures of the clivus were identified. The mean age of these patients was 9 years (range 1-16 years). Eleven (68.8%) of the 16 patients had an associated traumatic diastasis of the central skull base. Five (31.3%) of the 16 patients died. However, of the 11 patients who survived, all had a good outcome with a Glasgow Outcome Scale score of 4 or 5 at the time of discharge. The incidence of clival fractures among patients with head injuries was 0.33%. Clival fractures occur with a similar incidence in both the pediatric and adult trauma population. Outcome is not correlated directly with the extent of clival fracture, but rather with the presenting Glasgow Coma Scale score and concomitant brain parenchymal injuries. The identification of traumatic diastases in patients with clival fractures suggests that static loading forces are a significant factor in the biomechanics producing these types of fractures.

    ABSTRACT: LeFort I osteotomy is a standard technique for the surgical correction of dentofacial deformities. Despite its low morbidity, it can lead to various complications at the base of the skull. We report the case of a fractured clivus as an unusual complication.
