Earwax is clinically known as cerumen, and a lot of earwax may be related to excessive secretion of ceruminous glands in the external auditory canal and disorders of drainage. 1. Excessive secretion of ceruminous glands: If one suffers from otitis externa or a foreign body enters the ear, it may lead to increased secretion of ceruminous glands in the external auditory canal, and cerumen embolism is likely to occur after the increased secretion of cerumen. 2. Obstruction of cerumen discharge: under normal circumstances, cerumen may be discharged out of the ear along with speaking or chewing, but if there is narrowing of the external auditory canal or obstruction of foreign objects, it may lead to cerumen discharge being affected, and then cerumen impaction may occur. 3. Other factors: If excessive cerumen is found in the elderly population, it may be related to the decline in the motor function of the jaw joints, muscle relaxation, etc., because these changes will affect the discharge of cerumen, resulting in more cerumen. If there is excessive cerumen, it can be removed directly via cerumen hooks or ear foreign body pliers; or take warm saline rinsing to discharge; if necessary, via 5% sodium bicarbonate dabbing the ear to soften the cerumen, warm saline rinsing, or suction via suction.
