Earwax is the secretion of the cerumen gland in the cartilage of the external ear canal. From a medical point of view, it protects the skin of the external ear canal, absorbs dust and foreign objects, and prevents small insects from entering the deep part of the external ear canal. The cerumen can be discharged by itself through chewing and opening the mouth. If cerumen is secreted excessively or is obstructed from being discharged, it can accumulate in the external ear canal as a mass or become a hard lump, which is called cerumen embolism. When cerumen embolism is formed, it can affect hearing or induce inflammation, and is one of the common diseases in otolaryngology. If cerumen is blocking the ear canal, you should go to the ENT department of the hospital and let the doctor deal with it, otherwise it can cause hearing loss, ear pain, tinnitus, etc. Parents should never take an ear-pulling spoon, a small card or something like that and pull out the ear of your child on your own, children are active and accidents can easily happen. If the cerumen is hard and not easy to remove, or if the cerumen is closely embedded with the external ear canal and the patient has obvious pain during the removal process, you can first use 5% to 10% sodium bicarbonate solution to drip the ear 3 to 5 times a day and leave the affected ear upward for 5 to 10 minutes after each drip for 3 to 4 consecutive days to soften, then go to an ear, nose and throat specialist clinic and use an attractor to remove the softened cerumen. If the inner wall of the ear canal is congested after cleaning, you can take some anti-inflammatory drugs orally to treat the symptoms. If cerumen induces inflammation, you should first actively reduce inflammation and remove the plug as soon as possible to prevent poor drainage and inward spread of inflammation.
