My wife is scheduled for surgery with in intention to completely remove an arachnoid cyst from the posterior fossa. The cyst is a little larger than a golf ball and lies in the right hemisphere. The generic literature given indicates a ? shaped line of incision taking a complete side of the hair away; but this is literature is for a tumor that is more mid-line. My question is in relation to the location and shape the incision for a posterior fossa. She is aware that her hair will be shaved for the operation next week, and she wants to go to the hair dresser in order to have her hair grow back with some symmetry (not wanting to style the remains of her hair directly afterwards). Will the incision still take this much hair to be shaved, and will it still be on the side, or will it be more rearward facing?
