• The middle ear consists of the eardrum (tympanic membrane) and an air-filled chamber containing a chain of three bones (ossicles) that connect the eardrum to the inner ear (see Middle Ear). The middle ear acts as an amplifier of sound, whereas the inner ear acts as a transducer, changing mechanical sound waves into an electrical signal that is sent to the brain via the nerve of hearing (statoacoustic nerve).
    Middle and inner ear disorders cause many of the same symptoms, and a disorder of the middle ear may cause an inner ear disorder and vice versa.
    Middle ear disorders may occur because of

    Infection (such as acute otitis media, chronic suppurative otitis media, myringitis, or mastoiditis)
    Blockage of the eustachian tube (which connects the middle ear and the back of the nose)
    Injury (such as eardrum perforation, barotrauma, or objects in the ear)

    Doctors base the diagnosis on people
