Resumen
Introducción

El entrenamiento en la disección de los senos paranasales y la base de cráneo es esencial para el conocimiento anatómico y la correcta aplicación de las técnicas quirúrgicas. La visualización tridimensional de la anatomía endoscópica de la base de cráneo mejora la orientación espacial y permite la percepción de profundidad.

Objetivo

Mostrar la anatomía endoscópica de la base de cráneo basándose en la técnica tridimensional.

Métodos

Realizamos disección endoscópica endonasal en especímenes cadavéricos fijados con formol y con la técnica de Thiel, ambos con inyección intravascular de colorantes. Los abordajes fueron realizados con endoscopios convencionales 2D. Posteriormente aplicamos la técnica 3D anaglífica para ilustrar las figuras en 3D.

Resultados

Se ilustran las más importantes estructuras y referencias anatómicas de la región selar desde la perspectiva endonasal endoscópica en 3D.

Conclusión

La base del cráneo está compuesta por complejas estructuras óseas y neurovasculares. La experiencia con la disección en cadáver es crucial para comprender la anatomía y desarrollar habilidades quirúrgicas. La visualización 3D representa una útil herramienta para comprender la anatomía de la base de cráneo.

Abstract
Introduction

Training in dissection of the paranasal sinuses and the skull base is essential for anatomical understanding and correct surgical techniques. Three-dimensional (3D) visualisation of endoscopic skull base anatomy increases spatial orientation and allows depth perception.

Objective

To show endoscopic skull base anatomy based on the 3D technique.

Methods

We performed endoscopic dissection in cadaveric specimens fixed with formalin and with the Thiel technique, both prepared using intravascular injection of coloured material. Endonasal approaches were performed with conventional 2D endoscopes. Then we applied the 3D anaglyph technique to illustrate the pictures in 3D.

Results

The most important anatomical structures and landmarks of the sellar region under endonasal endoscopic vision are illustrated in 3D images.

Conclusion

The skull base consists of complex bony and neurovascular structures. Experience with cadaver dissection is essential to understand complex anatomy and develop surgical skills. A 3D view constitutes a useful tool for understanding skull base anatomy.
