There is no such thing as a medical term as earwax impaction, which may refer to cerumen embolism and can be softened with 5% sodium bicarbonate solution.
There are ceruminous glands in the skin of the external auditory canal that can secrete cerumen, which can usually be discharged by chewing.
If the cerumen accumulates more, evaporates after a long time, is hard and blocks the ear canal, which can lead to stuffy, blocked ears and hearing loss, etc., it can be soaked in 5% sodium bicarbonate solution to soften the cerumen, and then sucked out with negative pressure suction.
