Summary
Understanding anatomical variations is crucial for safe endoscopic endonasal surgery. This study details key skeletal, vascular, and neural variations encountered during nasal, sphenoid, and sellar approaches, offering a preoperative checklist.
Area of Science:
- Neurosurgery
- Anatomy
- Endoscopic Surgery
Background:
- Safe and efficient surgery relies on anatomical knowledge.
- The endoscopic endonasal approach is a preferred surgical route for accessing sellar pathologies.
Purpose of the Study:
- To describe anatomical variations encountered during endoscopic endonasal surgery.
- To provide a preoperative checklist for surgeons.
Main Methods:
- Review of skeletal, vascular, and neural anatomy relevant to the endoscopic endonasal approach.
- Description of variations encountered during nasal, sphenoid, and sellar phases.
Main Results:
- Detailed description of potential anatomical variations.
- Identification of critical structures and their variations.
- Provision of a comprehensive preoperative checklist.
Conclusions:
- Familiarity with anatomical variations is essential for successful endoscopic endonasal surgery.
- The preoperative checklist aids in surgical planning and safety.
