A Case of Endoscopic Transethmoidal Drainage of Subdural Abscess Originated from Dental Infection / 대한이비인후과학회지

ABSTRACT

Subdural empyema is fulminating purulent infection that develops between the dura and the arachnoid membranes. It is rare but one of the most immediate of neurosurgical emergencies, hence the importance of proper diagnosis and early intervention. Most subdural empyema complicated in the ENT field originate from sinonasal or otologic infections rather than dental infections. In our case of 64-years-old male, who was admitted with headache and fever, the diagnosed subdural empyema originated from odontogenic parapharyngeal abscess. We report that the case was successfully managed after urgent surgical drainage by endoscopic transethmoidal approach with long term intravenous antibiotics.
