Endoscopic sinus surgery for a tension pneumocephalus after severe cranio-facial trauma

Tension pneumocephalus is a rare form of pneumocephalus in which the air is under pressure; it is generally due to communication between the atmosphere and the intracranial cavity, and is an infrequent (0.88%) complication of cranial trauma. Tension pneumocephalus causes an increase in intracranial pressure with deterioration of the neurological situation and requires emergency treatment. Endoscopic surgery of the paranasal sinuses, which is generally applied in the diagnosis and treatment of fistulas with cerebrospinal fluid leakage, was here used to treat a case of pneumocephalus due to cranio-ethmoidal communication, in a patient we had treated previously for severe cranio-facial trauma.
