The ear drum is where the middle ear starts. Behind the ear drum is the middle ear space, which is normally filled with air. The opening of the eustachian (you STAY shun) tube is in the middle ear space. This tube connects the middle ear space with the upper part of the throat. The tube opens and closes many times during the day. A blocked Eustachian tube prevents air from reaching the middle ear. When this happens the middle ear can fill up with the fluid that can becomes thick, like glue over time. This problem is called glue ear or otitis media with effusion. The buildup of fluid in the middle ear reduces the movement of the eardrum and ossicles, and hearing is reduced. Acute Otitis Media Inflammation +/ infection of middle ear Short + severe episode Most common children Associated with respiratory infx/ blocked sinuses or ET(allergies/ enlarge adenoids) Bacteria-S. Pneumoniae, nzae, halis Viruses-RSV, Influenzae A+B, Rhinovirus. Germs enter the middle ear through the Eustachian tube. The Eustachian tube becomes blocked, trapping fluids in the middle ear cavity. The disease may be acute, (severe, but of short duration) or chronic (recurring or lasting a long time) In the acute stage pus collects in the middle ear cavity and causes hearing loss.

Otitis media is a group of inflammatory diseases of the middle ear. One of the two main types is acute otitis media (AOM), an infection of rapid onset that usually presents with ear pain. In young children this may result in pulling at the ear, increased crying, and poor sleep. Decreased eating and a fever may also be present. The other main type is otitis media with effusion (OME), typically. The authors report a rare case of primary intracranial meningioma presenting as a middle ear mass with conductive hearing loss. The authors aim to highlight the importance of diagnosing a middle ear mass, which although rare, may have a substantial impact on ongoing patient management. Diseases of external ear 1.
