Otogenic thrombosis of the lateral sinus, which has become rare since the use of antibiotics, nevertheless still poses diagnostic and therapeutic problems.

Management is then proposed in diagramatic form: the indication for surgery depending on the efficacy of antibiotic therapy and internal jugular vein ligation being required in the event of septic emboli manifest cervical signs.
