Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - Mastoiditis is an infection or inflammation of the mastoid air cells often resulting from extension of purulent OM with progressive destruction and coalescence of air cells. Medial sinus wall erosion can cause cavernous sinus thrombosis, facial nerve palsy, meningitis, brain abscess, and sepsis.
