(1) Avoid noise and strong sound stimulation Strong sound can cause violent movements of the eardrum, which may affect the stability of the artificial auditory bone if it is implanted. (2) Keep away from changes in air pressure Large changes in ambient air pressure will affect the difference in air pressure between the inner and outer tympanic membrane, and the tympanic membrane will move accordingly with the change in air pressure, which in turn will affect the activity of the hearing bone. For example, when blowing up a balloon with high internal pressure, the balloon will expand outward, but when the balloon is deflated, it will shrink back. (3) Avoid contaminating the external ear canal with dirty water Do not go swimming in rivers or wild lakes. The water quality in these places cannot be guaranteed and may contain more pathogenic bacteria (enemy strong). In addition, when the water enters the ear, it dilutes the cerumen and reduces the acidity of the environment inside the ear (I weak), it may cause local inflammation. (4) Don’t pull out your own ears The cerumen (earworms, earwax) secreted inside your ears is acidic, has antibacterial properties, has a protective effect, and the ears have a self-cleaning function that allows them to gradually discharge these things outward on their own. If you feel that your ears are blocked and suspect that they are blocked, then you should go to the hospital and check with an electric otoscope, otolaryngoscope or rigid endoscope to see if there is cerumen blockage, foreign body retention or secretion retention? Then treat the symptoms. In the case of patients with radicular mastoid, it is even more important to visit the hospital regularly to clean the scabs to avoid affecting hearing or forming local infections.
