I've seen pressue to cheek wounds done bimanually.
The PA gloved up, put two 4X4 in buccal area inside mouth, held in place with two fingers, and used other hand to hold a couple 4X4's to outside of wound. Sat pt up, leaning head forward a little. It was a through wound from a razor blade, no mandib or maxillary fx, pt was alert oriented. Once bleeding was greatly slowed, replaced the inside pads, reinforced the outside pads, and massively taped them.
WATCH OUT for airway troubles in facial wounds, face trauma is alarming but not the easiest avenue to kill someone...until they inhale a gauze sponge or blood.
The one I could never figure out was the triangular bandage for fx mandib. Good luck breathing, especially if you can't swallow, or ther'e interior bleeding.
