Summary
The endoscopic endonasal approach (EEA) offers a minimally invasive path to the ventral skull base, enabling complex tumor removal with fewer risks. This technique minimizes brain retraction and enhances visualization for improved patient outcomes.
Area of Science:
- Neurosurgery
- Otolaryngology
- Minimally Invasive Surgery
Background:
- The endoscopic endonasal approach (EEA) has advanced beyond pituitary and sinonasal surgery.
- It is now widely used for ventral skull base pathologies, demonstrating significant efficacy and benefits.
Purpose of the Study:
- To review the evolution and application of the EEA in complex skull base procedures.
- To highlight the advantages and challenges associated with advanced endoscopic skull base surgery.
Main Methods:
- Literature review of case series and reports on EEA for ventral skull base surgery.
- Analysis of the technical challenges, learning curve, and reconstructive needs.
- Evaluation of the benefits and risks compared to traditional open approaches.
Main Results:
- EEA allows for complex, maximally invasive procedures via a minimally invasive corridor.
- Benefits include avoidance of neurovascular retraction, improved visualization, and direct tumor access.
- Challenges involve a steep learning curve, narrow corridor navigation, reconstruction complexities, and a higher risk of cerebrospinal fluid leaks.
Conclusions:
- Despite challenges, the EEA provides a significant advantage for accessing midline tumors by minimizing manipulation of displaced neurovascular structures.
- The approach offers improved visualization and a direct corridor, reducing potential injury to critical structures.
