ObjectiveSubdural empyema is a collected cranioencephalic suppuration between arachnoid and dura meninge space. Subdural empyema occurring after sinusitis is an uncommon but serious complication of paranasal sinus infections. The purpose of this study is to aware the clinician about this condition. MATERIAL ET METHOD: Four young male children had been admitted with expressed fronto-ethmoid sinusitis. The intracranial infection was confirmed by computed tomography scan of brain and sinus. Both drainage of the sinus and intracranial suppuration was performed at the same time surgical procedure and antibiotics administered during 4 weeks.ResultsThe subdural empyema was localized in the right temporoparietal region in 1 case, in the frontal lobe in the others cases. In 1 case, the frontal subdural empyema was associated with an inerhemispherique collection. One patient underwent a second drainage. Immediate post-operative outcomes were temporally complicated with convulsions and focal neurological deficit, in 1 case. This symptoms had regressed spontaneously. There was no case of death. The functional prognosis was bad, marked by lost vision in 2 cases, which was bilateral in 1 case.ConclusionA high index of suspicion of intracranial extension of sinus infection must recommended neuroradiological investigations. When suppurative collection is confirmed, an appropriated management of the infection between otorhinolaryngologists and neurosurgeons is necessary.
