Otogenic intracranial complications originate in the course of acute or chronic middle ear inflammations. Inflammatory changes in the middle ear and the pneumatic system participate in their origin. The infection spreads directly along vascular canals as well as via bone erosion. The most frequent etiological agents include Streptococcus pneumoniae, Haemophilus influenze and Pseudomonas aeruginosa. The TES symptoms may be local as well as metastatic. The treatment is either conservative (high doses of antibiotics, anticoagulation therapy and supportive treatment) of a radical therapy – ligation of internal jugular vein, uncovering of the sinus and removal of thrombus.
