If there is a strange ringing in the ear when chewing, it may be caused by active cerumen in the external ear canal striking the eardrum. Under normal circumstances, there is scattered cerumen in the external ear canal, and the movement of the temporomandibular joint during chewing and speaking can cause cerumen to be discharged gradually from the deep part of the external ear canal outward. If the cerumen has a certain degree of mobility, it can strike the eardrum and produce a strange sound. At this point, a combination of endoscopy is required to make a definitive diagnosis. If this is the type of disease described, you can try to use an aspirator to suck it out. For larger masses or those that are closer to the eardrum and cause significant pain when removed, you can use sodium bicarbonate to soak it several times and then rinse it with saline. Usually, it is not recommended to use cotton swabs to dig the ears, which very easily leads to the formation of cerumen embolism after the cerumen outside the external ear canal accumulates inward for a longer period of time, causing strange noises, hearing loss, tinnitus, and even vertigo.
