i had a c5-6 anterior fusion with donor bone and plate and screws in may 2006 after the surgery i also had a numb chin unfortulatly my surgen screwed
up and i had to get a posterior revision surgery this past april this doc was wonderful even though the surgery was very painful much worst then going though the front i am now very good and going back to work next month, my job entitles alot of heavy lifting but i healed enough to go back anyway after this last surgery i had no chin numbness. the doc had to clean up the other doctors mess and in doing so had to more the plate off the nerve which the other doc didn't do right, so if this is the kind of surgery you had it is possible that the plate is on a nerve . hope this helped and good luck to you deb
