Pneumocephalus and neurosurgery in rotary aircrew.

BACKGROUND: Pneumocephalus secondary to trauma or tumors can have varied symptom severity. It is important to recognize and quantify pneumocephalus for medical evacuation and treatment. This case presents current recommendations for travel in the literature and how they are applicable in returning to flying duties after neurosurgical interventions. CASE REPORT: This is the case of a Naval aircrew member who developed an osteoma and subsequently periorbital emphysema and pneumocephalus. This required medical evacuation from a remote territory, a team surgical approach, and later testing to allow him to return to flight duties in rotary aircraft. DISCUSSION: A search of the literature did not reveal any previous cases of civilian or military flight crew having returned to flying duties after pneumocephalus or neurosurgery. Barometric chamber testing was performed post-operatively to provide clearance. Literature review revealed mixed advice on when one can safely fly commercially after neurosurgery and may be applicable in a case series of medical evacuation or future clearance in returning to flight duties.
