RT Journal Article SR Electronic T1 Effective but uncommon treatment of a spontaneous otogenic epidural pneumocephalus JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e228245 DO 10.1136/bcr-2018-228245 VO 12 IS 4 A1 Veit-Maria Hofmann A1 Annett Pudszuhn A1 Stefan Markus Niehues YR 2019 UL http://casereports.bmj.com/content/12/4/e228245.abstract AB We describe an uncommon treatment for epidural pneumocephalus and an effective but uncommon treatment option. Complete and permanent relief was achieved in a young patient using a tympanostomy tube to eliminate excessive positive air pressure in the mastoid bone that was the cause of spontaneous pneumocephalus. The patient showed no recurrence and absence of clinical symptoms at outpatient follow-up. Post-traumatic, infectious or spontaneous pneumocephalus may require an active, usually surgical approach. Treatment with a tympanostomy tube can be an alternative in suitable patients.
