I've repaired worse ones than that. I use foam-safe cyanocacrylate glue. I put the glue on and put the two parts together. When I'm happy with the fit, I give a quick spray with the activator while I hold it, which sets it in seconds, then on to the next piece of the jigsaw. Sometimes, there's a piece missing, no matter how careful I am to pick up all the pieces after the crash, so I cut a clean shape in the area of the missing piece, then make a piece to fit out of the eps packaging that came with my last TV.
