I was hit pretty hard with a wrench on what i think is my zygomatic bone no fracture but now i have issues with my sinuses. possible the hit is cause?

Depends: This is hard to answer without a full history and physical and reviewing your chart. If you had a CT scan it may not have shown a zygomatic fracture, but you may have had fractures of the maxillary sinus wall. Typically these don't require repair and may sometimes not even be mentioned to the patient. If thats the case, then yes the two could be related. I would review your previous records.

Maybe (not) . . .: What sinus issues are you suffering from? Perhaps, it's just coincidental. Sinus congestion is common result of allergies & pollen exposure, not to mention myriad cold viruses. See your Family Doc or ENT if no improvement w/OTC antihistamines & decongestants (assuming that you're bothered by allergies & congestion). If double vision or increase pain, then see ENT & Ophth immediately.
