based on what you now about the maxillary sinus, why would significant impact to maxilla create a more difficult situation for healing than would a fracture to a long bone?

due to the maxillary sinus, there isnt much bone in the wall of maxilla. Long bones are thicker and easier to set. The healing of maxilla is like trying to put an eggshell back together.

forms cranial roof and part of lateral walls -Bordered by 4 sutures - coronal, sagittal, lambdoid and squamous

frontal bone

forms forehead, part of cranial roof, and roof of orbit

foramen ovale
