Summary
The extended frontobasal approach offers good midline exposure for skull base tumors. This technique was used in 13 patients, with gross total excision achieved in most cases.
Area of Science:
- Neurosurgery
- Skull Base Surgery
Background:
- Extensive anterior and anterolateral skull base tumors pose significant surgical challenges.
- Access to supra and parasellar regions, cavernous sinus, and sphenoclival areas requires specialized approaches.
Purpose of the Study:
- To review the operative technique, indications, and complications of the extended frontobasal approach.
- Evaluate the efficacy of the extended frontobasal approach in managing complex skull base tumors.
Main Methods:
- Retrospective review of 13 patients operated between November 1991 and August 1999.
- The extended frontobasal approach was used alone or combined with subtemporal-infratemporal or transfacial approaches.
- Tumor excision and basal repair techniques were analyzed.
Main Results:
- Gross total excision was achieved in 8 patients; partial excision was necessary for malignant tumors and a fungal granuloma.
- Combined approaches were utilized in 6 patients.
- Complications included cranial nerve paresis, endophthalmitis, CSF leak, and internal carotid artery injury.
Conclusions:
- The extended frontobasal approach provides adequate midline exposure for challenging skull base tumors.
- While effective, the approach is associated with potential complications that require careful management.

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
