Benjamin reported visual improvement in 73%, stable vision in 20%, and deterioration in 7% of patients
[31]
who had visual loss before surgery. Pamir et al. also reported improvements in visual function in the
majority of 43 patients with anterior clinoidal meningiomas with a mean tumor diameter of 3.35 cm,
including 16 patients with tumors larger than 4 cm in diameter. Among 26 patients who had preoperative
visual deficits, 84.6% improved and 15.4% remained stable. The Russell and Pamir teams used an intradural
approach. In our series, there were no deaths, in comparison with 5%-15.4% mortality in some recent series.
