When patients have a situation where earwax is pushed deeper, they can no longer blindly clean out the ear canal on their own, and they need to seek medical help in a timely manner at the hospital. Patients are often in the ear canal to form clumps of cerumen embolism, and even this cerumen clumps hard texture, difficult to be successfully cleaned out directly. When the patient goes to the hospital for treatment, the doctor can remove the cerumen by using specialized tools such as tweezers or cerumen hooks. If the cerumen mass is relatively large or even hard, it is often necessary to use phenol-glycerin ear drops, sodium bicarbonate solution, etc., to first soften and dilute the cerumen mass, and then further use suction and other tools to remove the cerumen mass to avoid causing damage to the ear canal or even the eardrum.
