title: Subdural empyema and unilateral pansinusitis due to a tooth infection.
abstract: Paranasal sinus infections are very common. Dental infections, tumours and anatomical malformations can cause unilateral sinusitis. Most cases can be treated without complications. However, rare life-threatening intracranial complications can occur. Generally, an intracranial complication progresses rapidly and can cause meningismus, focal neurological disorders, loss of consciousness and seizures. In such cases, an emergency craniotomy and concurrent sinus surgery are required. This article presents a 16-year-old patient with pansinusitis and subdural empyema that developed after a dental abscess.
