  1. Volume: 1, volume < 20 cm3; 2, volume between 20 and 50 cm3; 3, volume > 50 cm3
  2. Arterial involvement: involvement of any artery was given one point, and an additional point was given for each of the following features: completely encircling (360°) the artery, involving more than one artery, and narrowing the lumen of the artery
  3. Cavernous sinus involvement: 0, tumor without cavernous sinus involvement; 2, tumor with cavernous sinus involvement
  4. Bone invasion: 0, tumor without bone invasion; 1, tumor with bone invasion
