Otogenic lateral sinus thrombosis in children: A review of 7 cases.

Otogenic lateral sinus thrombosis (LST) is a rare but serious intracranial complication of acute or chronic otitis media. Reported mortality rates have ranged from 8 to 25%; the pediatric mortality rate might be as low as 5%. Controversy still exists over the medical and surgical management of this condition. We conducted a retrospective chart review of 7 cases of pediatric otogenic LST that were treated at our institution over a period of 8 years. We hypothesized that good outcomes in very sick patients can be achieved by aggressively managing the mastoid cavity and without the need for a thrombectomy. Our study group was made up of 4 boys and 3 girls, aged 6 to 15 years (mean: 11.1). All patients received intravenous antibiotics and underwent mastoidectomy with unroofing of the sigmoid sinus and placement of a tympanostomy tube. Sinus exploration with thrombectomy was not performed in any patient. Anticoagulation was used perioperatively in 5 patients (71%) without complication. All patients recovered well without major sequelae, which supports our hypothesis. We also describe the case of a patient with multiple concomitant intracranial comorbidities associated with this rare condition.
