Summary
The endoscopic endonasal approach (EEA) provides a safe and effective method for accessing medial intraconal space (MIS) orbital lesions. This minimally invasive technique yields favorable outcomes with reduced postoperative complications for orbital tumor management.
Area of Science:
- Neurosurgery
- Ophthalmology
- Otolaryngology
Background:
- Orbital intraconal space lesions are rare and pose management challenges.
- Endoscopic endonasal approach (EEA) techniques for medial intraconal space (MIS) tumors are not well-documented.
Purpose of the Study:
- To evaluate the safety and efficacy of the EEA for managing isolated intraconal orbital lesions.
- To characterize operative techniques and outcomes for EEA in the MIS.
Main Methods:
- Retrospective review of 20 patients (2014-2021) with MIS lesions managed via EEA.
- Lesions included cavernous hemangioma, schwannoma, lymphoma, inflammatory pseudotumor, fungal sinusitis, and metastatic disease.
- Access via endonasal corridor; two-surgeon technique for dissection; biopsy or resection performed.
Main Results:
- Gross total resection achieved in 90% of benign lesions; 100% diagnostic yield for biopsies.
- 80% of patients had returned visual acuity; 90% resolved diplopia within 3 months.
- No orbital reconstruction needed; mean follow-up of 15 months.
Conclusions:
- EEA is a safe and effective surgical option for MIS intraconal orbital lesions.
- The technique offers favorable outcomes with minimal postoperative morbidity.
