OBJECTIVES With the advent of microdebriders and image guidance systems, endoscope-assisted surgery is now more widely used for the treatment of tumors involving the base of the skull. The aim of this study was to analyze the clinical features of tumors involving the anterior skull base and to evaluate the treatment outcomes according to the surgical approach, which included the traditional cra...

Three patients are described; in two of them initial plain skull films at an outside institution were interpreted as demonstrating an anterior clinoid meningioma. Evaluation of these films along with further study of the skull base with complex motion tomography demonstrated a separate and well corticated bony structure posterior and superior to each anterior clinoid in all three cases. After r...

Endoscopic endonasal surgery has become a standard procedure for functional treatment of benign pathologies. Materials and improved surgeon skills have allowed the number of indications for this approach to increase. We describe some of the main pathologies, including malignancies, that can be treated endoscopically, focussing on the orbital and skull base pathologies. The orbital indications d...

BACKGROUND Anterior and posterior ethmoid arteries supply the paranasal sinuses, septum, and lateral nasal wall. Precise identification of these arteries is important during anterior skull base procedures, endoscopic sinus surgery, and ligation of ethmoid arteries for epistaxis refractory to standard treatment. There is controversy in the literature regarding the prevalence of supernumerary eth...

We report a case of a 52-year-old man who presented with iatrogenic bilateral nasoethmoidal meningoencephaloceles following endoscopic nasal surgery performed in a neighboring country 8 years ago. Imaging studies, including computed tomography and magnetic resonance imaging of the paranasal sinuses and anterior skull base, demonstrated bilateral meningoencephaloceles and a suspicious intracrani...
