These are some photos from real people who have been through the surgery.

The scar a week after surgery.

One week following the second surgery, four weeks after the first surgery.

Both these pictures are taken a year after surgery - after a hair cut!!! i wear my hair short - I always have - the scar is still noticeable but this does not concern me because I cannot see it!

One week after surgery - the blue stitches indicate where the patient had a spinal leak following surgery.

This is the same patient three weeks after her surgery.

As you can see this patient had more hair shaved, and staples used. This shows how different surgeons differ in their approach to this surgery.
