title: Tension pneumocephalus after endoscopic sinus surgery: case report of repair and management in absence of obvious skull base defect.
abstract: Tension pneumocephalus is a rare complication of functional endoscopic sinus surgery that may lead to rapid neurologic deterioration. Patients typically display symptoms within hours after the operation, and computed tomography reveals the presence of a skull base defect. We report a unique case of subacute tension pneumocephalus with no obvious skull base defect, which was associated with a pupil-involving third-nerve palsy. We discuss management of this complication and preventive measures for avoiding pneumocephalus after functional endoscopic sinus surgery.
