Question: What is the "halo" and why is it necessary? Rev.03/03
Answer: The "halo" is a device which is secured to the head during the pre-surgical MRI and then is reapplied for the procedure. It is to ensure that there is no movement during the diagnostic testing and surgery. This is done by placing the halo over the head and securing it with 4 screws. For some people this is the most uncomfortable part of the operation.
With the halo's help coded information is fed to the computer and permits the accurate placement of the electrodes by the surgeon.
When I had my halo put on, I was wide-awake. The surgeon took time to discuss my fears, and this part did scare me - more than the surgery. He explained what he'd do; it was similar to getting shots in your mouth before a dental procedure. The first one stung, then nothing. He gave several shots per area but I only felt the first one. He deadened each of the four areas. Four stings, and it was over. The surgical nurse stood behind me and massaged my shoulders the entire time, which really helped. Nothing beats the human touch for comfort.
I think I was mostly nervous about scarring from the halo, and there are NO scars from that!
