Left untreated, cerumen impaction in the ear can lead to consequences such as hearing loss, infection of the external ear canal, and cholesteatoma of the external ear canal due to the increasing accumulation of cerumen. Cerumen, commonly known as earwax, is normally discharged naturally with the movement of our head. However, in some patients, due to congenital hereditary factors, cerumen is oily and difficult to be removed. As more and more cerumen accumulates in the ear canal, it will block the ear canal, which is called cerumen impaction. Cerumen impaction over time will lead to symptoms of ear stuffiness and blockage and hearing loss. It may also compress the tympanic membrane and irritate the skin of the external auditory canal, leading to infection of the skin of the external auditory canal causing otitis externa, and cholesteatoma of the external auditory canal when abnormal keratinization and proliferation of the compressed skin of the external auditory canal occurs. Patients with cerumen embolism should consult the ENT department in a timely manner to dispose of the cerumen embolism and possible symptoms and diseases under the guidance of a physician.
