Summary
This study details endoscopic extended transsphenoidal approach anatomy, revealing distinct visual characteristics compared to microscopy. Precise landmarks are crucial for navigating the central skull base effectively.
Area of Science:
- Neurosurgery
- Anatomy
- Endoscopic Surgery
Background:
- The extended transsphenoidal approach is vital for accessing the central skull base.
- Understanding endoscopic anatomy is critical for surgical success.
Purpose of the Study:
- To delineate pertinent anatomical data for the extended transsphenoidal approach using endoscopy.
- To investigate anatomical characteristics and methods under endoscopic visualization.
Main Methods:
- Dissection, observation, measurement, and photography of 25 adult cadaver heads.
- Focus on neural and vascular structures and anatomical landmarks relevant to the endoscopic extended transsphenoidal approach.
Main Results:
- Endoscopic bilateral approach provides excellent exposure of the sphenoidal sinus posterior and lateral walls.
- Endoscopy enhances illumination, magnification, and provides 2D images, though image distortion is possible.
- Defined vertical compartments (midline, paramedian, lateral) and nasal cavity landmarks aid surgical navigation.
Conclusions:
- Endoscopic visualization of anatomical characteristics differs from microscopic views.
- The endoscopic extended transsphenoidal approach offers expanded vision and exposure for central skull base surgery.
