Fever and a new severe headache after a sinus, dental, orbital, ear, or mid face infection should not be treated as uncomplicated local infection when eye findings are developing.
Fever and a new severe headache after a sinus, dental, orbital, ear, or mid-face infection should not be treated as uncomplicated local infection when eye findings are developing. Cavernous sinus thrombosis (CST) is usually a septic clot in one of the paired dural sinuses at the skull base. Venous obstruction and inflammation impair orbital drainage and affect the cranial nerves that control eye movement. Because the two sinuses communicate, disease can cross to the opposite side quickly. Arrange urgent venographic imaging and specialist management while antimicrobial therapy is prepared.
