Intracranial complications of frontal sinusitis.
Frontal sinus infections can spread to the intracranial space so fast that the clinical situation often becomes far advanced before a complication is recognized. Retrograde septic thrombophlebitis is the most common pathway of extension. A review of recent experiences with fulminating frontal sinusitis and its intracranial complications such as subdural empyema, brain abscess, epidural abscess, and meningitis is presented. Neurologic features of intracranial invasion are interpreted. Good results have been achieved by immediate and aggressive surgical and medical measures.
