title: The subcranial approach for fronto-orbital and anteroposterior skull-base tumors.
abstract: We describe 78 patients with fronto-orbital and sphenoethmoidal tumors surgically treated with the subcranial approach. This approach was developed by us in 1978 primarily for the treatment of skull-base trauma and craniofacial anomalies. Since 1980, we have extended the indications to include tumor resections. This extended anterior exposure of the anterior fossa skull base, including the sphenoidal and clival planes, enables an en bloc tumor removal obviating the transfrontal approach or lateral rhinotomy. In contrast with the conventional transcranial approach, the anterior subcranial approach provides an extended exposure of these locations, avoiding frontal lobe retraction. Reduction of complications, such as recurrent cerebrospinal fluid leaks, postoperative brain edema, damage to cranial nerves, and infection plus decreased hospitalization, are the major advantages of this procedure.
