Anterior Cranial Fossa Traumas: Clinical Value, Surgical Indications, and Results—A Retrospective Study on a Series of 223 Patients

Abstract

Objective Frontobasal fractures are relatively common traumas but surgical indications are still discussed. The authors report their results on patients showing anterior cranial fossa fractures; clinical data, surgical indications, and results are reported and critically analyzed.

Methods From 1991 to 2010, 223 patients were admitted in our institution with diagnosis of anterior cranial fossa fracture. Fractures were classified as type A—fracture of the anterior wall of the frontal sinus; type B—fracture of the posterior wall of the frontal sinus; and type C—frontobasal traumas without involvement of the frontal sinus. All patients entered a follow-up program consisting in periodic controls.

Results A total of 105 patients were conservatively treated, while 118 patients underwent surgical intervention. The presence of pneumocephalus (p < 0.0001) and rhinoliquorrhea (p = 0.001) were the factors influencing the surgical indication. In the fractures of group B with signs of pneumocephalus and or rhinoliquorrhea, full sinus cranialization represents the variable mainly influencing the outcome (p < 0.001).

Conclusion Patients with frontobasal traumas should be carefully evaluated to choose the best treatment option. Clinical and radiological data suggest that patients with frontobasal fractures with massive pneumocephalus and/or rhinoliquorrhea should be always surgically treated.
