Cerumen impaction

Cerumen impaction represents the most common otologic problem encountered by physicians. It can affect up to 6% of the general population and a much higher percentage in the mentally retarded population. Cerumen is a mixture of secretory products of two glands in the external auditory canal where it serves a protective function. The external auditory canal possesses a unique anatomy and physiology that permits an efficient self-cleaning system. In most cases, a breakdown in the epithelial migration of the external auditory canal is thought to cause cerumen impaction. The management of cerumen impaction include direct removal, irrigation, and the use of cerumenolytics.
