Earwax formation of hard lumps in young children belongs to cerumen embolism, and the hard lumps are relatively small, so they can be removed directly with the external ear canal foreign body pliers; if the hard lumps of earwax are large, they need to be softened first before removal. It should be treated by a doctor in time. Hard lumps of earwax in young children can cause serious blockage of the ear canal. As the ear canal is deeper and narrower, it can cause damage to the ear canal if not handled carefully. In severe cases, it can also lead to tympanic membrane damage and perforation. Therefore, do not remove the hard lumps at home when you find them. If the volume of hard lumpy earwax in the ear canal is relatively small or flat, it can be removed directly by a medical professional with an external ear canal foreign body forceps under a light source. If the earwax in the ear canal accumulates into larger clumps and fits tightly around the ear canal, it is very difficult to remove directly. It is necessary to use 5% sodium bicarbonate to soften the cerumen first, and then use warm saline to rinse it after softening, or apply special tools such as suction to clean it out. When earwax forms hard lumps in young children, parents should bring their children to the otorhinolaryngology department of regular hospitals in a timely manner and have them operated by specialized doctors.
