What the heck is otitis media?

Inflamation mid/ear: Otitis media is a broad term that includes various forms of inflamation of the middle ear. That space is like a cave in the skull, with the ear drum on one wall, a drain tube (eustacion tube) in the floor ; another wall composed by the skull ; the ear nerve. The walls make mucous which normally drains but can be trapped. Germs can feed on the trapped mucous ; cause infection.
