The doctor that did my surgery specializes in neck and head cancer. Because cancer sucks enough, he likes to leave no visible scar. I do not know how he does it but the net result is a scar with two tiny knots at each end. To remove, they cut the knots at each end and pull on one side. It leaves a hair thin line of discoloration rather than your typical Frankenstein thick scar with staples or stitch lines.
