Selective amygdalohippocampectomy is an effective treatment option for mesial temporal lobe epilepsy associated with hippocampal sclerosis.
Methods To describe and emphasize potential pitfalls during selective amygdalohippocampectomy via a modified navigated temporobasal approach, in cases, where temporal basal veins hinder the required elevation of the temporal lobe.
Conclusions Selective amygdalohippocampectomy via navigated temporobasal approach is a safe procedure that can reduce the rate of visual field deficits by avoiding damage of optic radiation. The option of a small subpial corticotomy of the inferior temporal gyrus allows sufficient elevation of the temporal lobe in cases with difficult basal venous anatomy.
