[A case report of epidural abscess caused by acute frontal sinusitis].

Epidural epidural abscess is usually secondary to acute frontal sinusitis and osteomyelitis of the frontal bone. Nose-derived intracranial connplications are less common than otogenic ones, and infections caused by nasal and sinus trauma, foreign bodies and surgery are more common than those caused by inflammation alone. The frontal lobe abscess caused by frontal sinusitis is more common in brain abscess with nasal intracranial complications.
