Summary
Microscopic endonasal optic nerve decompression offers a minimally invasive approach for vision restoration in trauma and tumor cases. This technique shows promising results, improving vision in over half of traumatic cases and the majority of tumor cases.
Area of Science:
- Neurosurgery
- Ophthalmology
- Skull Base Surgery
Background:
- Optic nerve decompression is gaining clinical interest.
- Standardized treatment protocols for optic nerve insults are lacking.
- Minimally invasive techniques are sought to reduce operative trauma.
Purpose of the Study:
- To report outcomes of microscopic endonasal transethmoid-sphenoid optic nerve decompression.
- To evaluate the efficacy in traumatic and tumor-related optic nerve compression.
- To compare the technique's invasiveness with traditional methods.
Main Methods:
- Retrospective study of 24 unilateral trauma cases and 11 unilateral skull base tumor patients.
- Microscopic endonasal transethmoid-sphenoid approach for optic nerve decompression.
- Analysis of preoperative and postoperative visual acuities.
Main Results:
- Tumor patients: 82% (9/11) showed vision improvement, with 5 complete recoveries.
- Trauma patients: 54% (13/24) improved vision, 4 regaining normal/near-normal vision.
- Preoperative vision was generally worse in trauma patients compared to tumor patients.
Conclusions:
- Microscopic endonasal optic nerve decompression is effective for vision recovery in selected cases.
- The transethmoid-sphenoid approach is minimally invasive, avoiding skin incisions and craniotomy.
- This technique reduces operative trauma to surrounding nasal structures.
