Abstract
Epithelial migration plays a crucial role in maintaining the health of the ear canal and tympanic membrane. This process involves the movement of keratinocytes, and it serves to eliminate debris, prevent cerumen (earwax) buildup, and facilitates the healing of tympanic membrane damage. Keratinocytes not only acts as a physical barrier but also have immunological capabilities to protect the ear canal from contaminants. Failure of epithelial migration can lead to ceruminoliths, which are hard earwax concretions that can cause discomfort and even hearing loss. Ceruminoliths are commonly associated with factors like over production of cerumen, obstruction in the ear canal, and damage to the germinal epithelium. Diagnosis of ceruminoliths typically involves otoscopic examination and otic cytology. Management options include cerumenolytic agents, irrigation, and manual removal under vision, each with its own considerations and precautions. Treatment of the underlying cause, such as ear mite infestations, may also be necessary to prevent ceruminolith formation. This comprehensive review sheds light on the mechanisms, causes, diagnosis, and management of ceruminoliths, emphasizing the importance of ear health and the various strategies for effective removal.
