There are three types of ear blockage in children: First, there is a foreign body in the child’s ear, a small toy or food that is accidentally stuffed into the ear while playing, which can be removed by a doctor at the hospital to avoid damaging the eardrum and not affecting the child’s hearing. It is best to use sodium bicarbonate ear drops to soften the earwax before going to the hospital to have it cleaned out. If your child has otitis externa or purulent otitis media, it is often necessary to use antibiotic drops such as levofloxacin ear drops in the ear, and it is best to take oral antibiotics to reduce inflammation.
