This blocks include side and type of the first surgery which was extracted from the table in line before: Right side and Three-corner flap, right side and envelope flap, left side and three-corner flap, and left side and envelope flap. These data would be given in 4 sealed pockets to the surgeon and surgeon would pick one of them. After that, surgeon will operate patient according to the selected data. Every 4 patient must undergo surgery according to one of these pockets.The other flap on the other side would be operated according to the picked pockets.
