Aeronautical otitis media is actually acute otitis media, which is also called aeronautical otitis media because of the exact cause of the flight. The main reason for aviation otitis media is that during the flight at high altitude, the pressure inside and outside the tympanic membrane is balanced, but it is smaller than the atmospheric pressure on the ground. However, in some cases, when the lack of ventilation in the eustachian tube lasts for a longer period of time, the negative pressure in the tympanic chamber lasts for a longer period of time, which can easily cause edema and exudation of the mucous membrane in the eustachian tube and aggravate the lack of ventilation in the eustachian tube, resulting in the symptoms of acute otitis media. The early manifestations of aviation otitis media may only have symptoms such as ear stuffiness, ear swelling and hearing loss, but when aggravated, there are symptoms of ear pain or even severe pain, and the symptoms of ear pain will be alleviated when pus flows out of the tympanic chamber after the tympanic membrane is perforated. If the treatment is not timely, it can become chronic otitis media. In the course of the disease, there can be an interruption in the recovery process at any time due to timely treatment. The symptoms of secretory otitis media may appear when the ear is stuffy and swollen in the early stages and hearing loss is not treated in a timely manner, but the duration of secretory otitis media varies from person to person. When the pus does not heal, it can lead to chronic middle ear mastoiditis, which is not easily cured and can cause ongoing hearing damage. In a few cases, the secretion of otitis media will cause the tympanic glue ear for a long time, making it difficult to recover hearing.
