Quantitative Analysis of Optic Canal Superior Wall Decompression in Endoscopic Endonasal Resection of Tuberculum Sellae Meningiomas

Key Points

• This analysis investigates how optic canal superior wall decompression impacts visual outcomes in the surgical removal of meningiomas.
• Quantitative analysis of optic canal superior wall decompression during surgery
• Assessment of tumor complexity and size
• Evaluation of visual improvement post-surgery
• Wider optic canal superior wall decompression correlates with greater odds of visual improvement
• The effect remained significant after adjusting for tumor size
• Adequate decompression supports safer surgical dissection
