The treatment of hardened earwax is that the hardened cerumen can be softened first, and then the hardened cerumen can be removed or rinsed out of the external auditory canal using saline solution after softening. Earwax is also called cerumen, cerumen clumps are relatively common in clinical practice. If the cerumen clumps are large, cerumen embolism will be formed in the external auditory canal, and the treatment can be softened by using sodium bicarbonate solution or liquid paraffin drops to soften the cerumen clumps, about 4~6 times a day for 4~5 days, and basically the cerumen clumps can be softened. If the softened cerumen is in solid form, it can be gently removed with small tweezers or an ear scoop; if the softened cerumen has turned into liquid form, then the outer ear canal can be flushed out with saline to flush out the cerumen in the outer ear canal. If the symptoms of cerumen hardening into lumps appear, please seek medical treatment promptly and standardize the treatment.
