Sie tritt vorwiegend bei \u00e4lteren, immunsupprimierten Patient:innen \u2013\u00a0v.\u00a0a. mit Diabetes mellitus\u00a0\u2013 auf. Die Erkrankung kann in eine Osteomyelitis der Sch\u00e4delbasis \u00fcbergehen, ggf. mit schwerwiegenden Komplikationen wie Hirnnervenparesen, Meningitiden oder Sinusvenenthrombosen.

Die therapeutische Basis bildet eine gezielte systemische antimikrobielle Behandlung \u00fcber mehrere Wochen. In komplizierten Verl\u00e4ufen kann eine chirurgische Intervention erforderlich sein.
