Problems involving the middle part of the ear include otitis media and otitis media with effusion.
This is a build up of fluid in the middle part of the ear which can block the movement of the ear drum and reduce the level of hearing. Hearing loss may range from mild to severe, and may even vary from day to day, making it difficult to identify. There is generally no pain, however there may be a feeling of fullness in the ear. Sounds, if heard, may be muffled or distorted. It is not always easy for a doctor to detect when looking into an ear.
