Fully Endoscopic Supraorbital Approach for Anterior Cranial Base Meningiomas.

Area of Science:

• Neurosurgery
• Minimally Invasive Surgery
• Endoscopic Techniques

Background:

• Anterior cranial base meningiomas, including those of the tuberculum sellae, planum sphenoidale, and olfactory groove, are primarily treated with surgical excision.
• The supraorbital keyhole approach, using microscopic or endoscope-assisted techniques, has become a common minimally invasive option.
• Rigid endoscopes enhance visualization in small surgical exposures, offering advantages over microscopic views in brain surgery.

Purpose of the Study:

• To elaborate on the surgical technique and nuances of the fully endoscopic supraorbital approach for anterior cranial base meningiomas.
• To present a detailed account of a specific minimally invasive surgical technique.

Main Methods:

• Analysis of clinical data, imaging, operative charts, and videos from a prospective database of endoscopic procedures.
• Review of pertinent scientific literature on endoscopic cranial surgery.

Main Results:

• Formulation of the surgical technique for the fully endoscopic supraorbital approach to anterior cranial base meningiomas.
• Demonstration of the technique's application in treating these specific tumors.

Conclusions:

• The fully endoscopic supraorbital approach presents numerous advantages compared to conventional methods.
• This technique is proven to be feasible, efficient, and minimally invasive, yielding excellent outcomes in clinical practice.
