Accumulation of fluid in the cavity of the middle ear, causing impaired hearing. Persistent glue ear is most common in children. It is often accompanied by enlarged adenoids and frequently occurs with viral respiratory tract infections, such as the common cold. Usually both ears are affected. The lining of the middle ear becomes overactive, producing large amounts of sticky fluid, and the eustachian tube becomes blocked so that the fluid cannot drain away. The accumulated fluid interferes with the movement of the delicate bones of the middle ear. Glue ear is sometimes first detected by hearing tests. Examination with an otoscope can confirm the diagnosis. In mild cases, the condition often clears up without specific treatment. If the condition persists, it may be necessary to insert grommets, which allow air into the middle ear and encourage fluid to drain. Adenoidectomy may also be required.
