Abstract:
Anterior skull base meningiomas often cause visual decline by compressing the optic apparatus. The authors present a tuberculum sellae meningioma with optic canal involvement treated via an endoscopic endonasal approach (EEA). Early devascularization, stepwise detachment, and sharp dissection preserved surrounding neurovascular structures and perforating arteries. Optic canal drilling enabled complete removal, and multilayer reconstruction ensured watertight closure. Gross-total resection was achieved without complications. Visual acuity improved from 0.7 to 1.2, with resolution of visual field defect. This case highlights the EEA as a standard technique for optimal visual outcomes in anterior skull base meningiomas with optic canal involvement.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
