A sudden loss of hearing is considered an ENT emergency. The most important part of the treatment is to be evaluated by an ENT specialist as soon as possible. The ear must be examined and an audiogram must be performed in order to determine the cause of the sudden change in hearing.
Many times, the cause of the sudden change in hearing can be easily identified and treated. Common causes include a wax impaction, an ear infection or a foreign body in the ear. This is called a conductive hearing loss.
