Summary
The endoscopic endonasal approach is a viable surgical option for selected intraorbital tumors, offering improved vision and tumor removal. This minimally invasive technique shows promise for both intraconal and extraconal orbital lesions.
Area of Science:
- Neurosurgery
- Ophthalmology
- Endoscopic Surgery
Background:
- Intraorbital tumors present surgical challenges.
- Traditional surgical methods have limitations.
- Endoscopic endonasal approaches offer a novel corridor.
Purpose of the Study:
- To evaluate the feasibility and outcomes of the endoscopic endonasal approach for intraorbital tumors.
- To assess the safety and efficacy of this minimally invasive technique.
Main Methods:
- Retrospective review of 6 consecutive intraorbital tumors treated between April 2018 and October 2020.
- Endoscopic endonasal resection was performed.
- Cadaveric dissection and literature review informed the intraconal approach.
Main Results:
- Five tumors were intraconal, one extraconcal; pathologies included schwannomas, meningioma, and others.
- Gross total resection was achieved in 5 out of 6 patients.
- Postoperative visual improvement occurred in all 4 patients with preoperative deterioration; transient oculomotor nerve palsy in one.
Conclusions:
- The endoscopic endonasal intraconal approach is suitable for selected intraorbital tumors.
- This technique is effective for medial and beyond medial extraconal and intraconal tumors.
- The approach offers good oncological and functional outcomes with minimal complications.
