Eligibility Criteria
You may qualify if:
- \. Adult patients aged 18 years or older. 2. Patients with radiologically confirmed skull base lesions (based on MRI ± CT) involving the anterior, middle, or posterior skull base.
- \. Patients undergoing lesion resection using the extended endoscopic endonasal approach (EEEA).
- \. Lesions amenable to endoscopic endonasal access, including: Pituitary adenomas with extrasellar extension Craniopharyngiomas Skull base meningiomas Chordomas and other midline skull base lesions 5. Availability of complete preoperative assessment, including: Clinical evaluation Neuro-ophthalmological assessment (when applicable) Radiological imaging 6. Availability of detailed intraoperative data, including surgical approach and intraoperative findings.
- \. Availability of early postoperative MRI (within 72 hours to 3 months) to assess the extent of resection.
- \. Patients with adequate postoperative follow-up (minimum 3 months) for evaluation of outcomes and complications.
You may not qualify if:
- \. Patients aged less than 18 years. 2. Patients who underwent transcranial approaches. 3. Lesions not primarily involving the skull base or not suitable for endoscopic endonasal access.
- \. Patients with incomplete clinical, radiological, or operative data. 5. Absence of early postoperative MRI, making assessment of the extent of resection unreliable.
- \. Patients with insufficient follow-up (less than 3 months). 7. Cases managed by biopsy only without attempted lesion resection. 8. Patients with severe comorbidities significantly affecting surgical outcome (e.g., advanced systemic disease), if they introduce bias in outcome assessment.
