1)      CAVERNOUS SINUS THROMBOSIS

Spreading of maxillary infections can cause carvenous sinus thrombosis. It is a very life threatening situation  whereby blood blot is formed in the cavernous sinus. (Cavernous sinus is a small cavity at the base of brain that contains arteries, veins, and nerves)
