Information regarding Surgery

Hi, I am 25 years old, I have partial complex seizures, and I was reason diagnose with Mesial Temporal Lobe Epilepsy. I have been taken medicine since I was about 13 years old. I have been on a least 4 different medicines and the medicines are not working for me. I was referred to a to specialist at Washington University in Saint Louis, and I under took some testing. I had to take a pet scan, MRI, and was put on EEG monitoring so they could find where my seizures was coming from. Every thing match to left temporal lobe and all the test match the same spot in which the seizures were coming from. The doctors think I an excellent candidate for surgery with a 60-80 percent chance of not having seizures. I am now at the stage of making a serious decision on what choice I should make regarding my seizures. I could have left temporal lobe surgery, try to find another medicine (which have a ten percent chance of controlling or preventing less seizures), or they could insert some thing like a pace maker kind of thing in my chest to send electros to the brain (which have a ten percent chance of controlling or preventing less seizures), or have a strict diet to follow to prevent or control the seizures.
