The ears and eyes, like the eyes, get information from the outside world through sound so that they can communicate with the outside world. If the ears are badly affected by hearing loss, the world will be a silent world for him. The ear lesions are good, but most of them can be detected and prevented at an early stage. Children are more prone to otitis media than adults, which is related to the development of the ear and eustachian tube in children, such as sinusitis or rhinitis in children, i.e., nasal congestion, runny nose and snoring symptoms, which can lead to otitis media in children. In adults, secretory otitis media is often associated with changes in air pressure, such as during airplane landings and takeoffs, and can also be caused by diving. If you have otitis media with secretion, you should go to an otolaryngologist. Sudden deafness has many causes and symptoms, such as hearing loss, tinnitus or vertigo, but treatment should be timely and generally as soon as possible after the onset of the disease.
