Objective: A survey-based study was designed to assess opinions related to transsphenoidal endoscopy, to evaluate the current global attitudes of neurosurgeons regarding the use of this procedure, and to solicit basic data from key institutions worldwide, with the advantage that large series of cases become available for analysis.
Methods: A web-based multi-item questionnaire was distributed to the surgical departments of 393 neurosurgical centers by means of an invitation e-mail. The questionnaire was composed of 2 sections: section 1 focused on the surgical technique for pituitary adenomas (standard technique), and section 2 concentrated on surgery for skull base tumors (extended technique).
This presentation is intended as a synopsis of the development of instrumentation in neurosurgery, with information about current status, evolution, and needs. Surgical instruments have been manufactured since the dawn of prehistory. Rough trephines for performing round craniotomies were discovered in Neolithic sites in many places.

Methods: Eighteen patients with lateral sphenoid wing meningiomas and tumor extension into the lateral or superolateral compartments of the orbital cavity were treated by microsurgical lateral orbitotomy and resection of the sphenoid wing without craniotomy. The approach consisted of a linear skin incision along the upper eyelid crease extending to 2 cm from the canthal angle and resection of the lateral orbital rim, lateral orbital wall, and infiltrated sphenoid wing.
Object: The extended transnasal approach, a recent surgical advancements for the ventral skull base, allows excellent midline access to and visibility of the anterior cranial fossa, which was previously thought to be approachable only via a transcranial route. The extended transnasal approach allows early decompression of the optic canals, obviates the need for brain retraction, and reduces neurovascular manipulation.
Methods: Between 2004 and 2007, 11 consecutive patients underwent transnasal resection of anterior cranial fossa meningiomas--4 olfactory groove (OGM) and 7 tuberculum sellae (TSM) meningiomas.
We present an overview of the history, development, technological advancements, current application, and future trends of cranial endoscopy. Neuroendoscopy provides a safe and effective management modality for the treatment of a variety of intracranial disorders, either tumoral or non-tumoral, congenital, developmental, and degenerative, and its knowledge, indications, and limits are fundamental for the armamentarium of the modern neurosurgeon.

Recently, the indications for the transsphenoidal technique, traditionally proposed only for the treatment of intrasellar lesions, have been extended to include lesions located in the supra- and parasellar areas and, among them, tuberculum sellae meningiomas. We describe the surgical technique for the purely endoscopic endonasal variant of the extended transsphenoidal "low route" to tuberculum sellae meningiomas.

Material And Methods: Sixty patients with spheno-orbital meningiomas operated upon between 1983 and 2003 were reviewed.
