[Subdural empyema and cerebritis as a sequela of dentogenous suppurative pansinusitis].

BACKGROUND

Complications and local extension of dentogenous and paranasal sinus infections most often involve the periorbit and frontal cranium. Because of the widespread use of antibiotics, intracranial extension of maxillofacial sinusitis is rarely seen today. Nevertheless, the clinician must be aware of the potential for these complications, because late recognition of this condition and delay in treatment can increase morbidity and mortality rates.

CASE REPORT: A case report of sinogenic intracranial complications is presented, with sinogenic empyema, cerebritis, and subdural empyema. The mechanisms and potential for intracranial spread of infection from the frontal, sphenoid, and ethmoid sinuses are discussed. The management of complications is outlined, including the use of computed tomography and the role of surgical drainage.
