Neuronavigation-Guided Endoscopic Endonasal Drainage of Pediatric Anterior Cranial Base Epidural and Subdural Empyema

In children, epidural and/or subdural intracranial empyema can complicate frontal sinusitis or pansinusitis. The standard transcranial approach used to treat epidural or subdural empyema has many drawbacks, but these can be avoided with an endoscopic expanded endonasal approach (EEA). To support the feasibility and advantages of this approach, we report the successful drainage through endoscopic EEA of a bifrontal empyema caused by an intracranial extension of pansinusitis. Our case and the ones previously reported in the literature establish well that endoscopic EEA offers several advantages over the standard craniotomy. Hence, EEA should be considered as an alternative to the transcranial approach when surgically draining anterior skull base empyema resulting from pansinusitis in children.
