 The head was put in a 3-pin Mayfield headholder with one pin in the forehead and two pins in the back to be able to put the patient with the right-hand side down and the left-hand side up since on the right-hand side, she did not have a bone flap which complicated matters a little bit, so we had to use a 3-pin Mayfield headholder.
