Tension pneumocephalus: a case following otologic surgery.

Asymptomatic pneumocephalus associated with cerebrospinal fluid drainage through a dural defect following extensive skull base surgery is not uncommon. Its occurrence following otologic surgery, however, is rare. Tension pneumocephalus, if not recognized, can rapidly lead to death due to increased intracranial pressure. A case of tension pneumocephalus is presented to demonstrate its clinical features and surgical management. The pathophysiology, diagnosis, and management of tension pneumocephalus are reviewed.
