  1. Arachnoid cysts were classified according to the Galassi classification system (for temporal cysts only) [26]. The postoperative neuroimaging outcome group (NOG) and clinical outcome group (COG) were classified according to the system used by Helland and Wester [23]. E, epilepsy; COG, clinical outcome group; D, dyscognition; H, headache; L, left side; NOG, neuroimaging outcome group; R, right side; V, vertigo/dizziness.
