What is it important for me to ask my neurosurgeon before having temporal lobe surgery for epilepsy?

RBA. In general, whenever you speak to a surgeon, always ask for 3 things: 1. Risks (what are the most common risks of the surgery) 2. Benefits (why do you need the surgery) 3. Alternatives (are there any alternatives surgeries or medications to the procedure being suggested).
Functional MRI. Ask if there is a role for any functional mri, as it may show eloquent brain regions ahead of surgery. Also, awake craniotomy may be considered in some cases. Your neurosurgeon may need neither for a standard amygdalo-hippocampectomy for mesial temporal sclerosis.
