Which ear condition is characterized by the accumulation of wax?

Cerumen impaction is characterized by the accumulation of ear wax (cerumen) in the ear canal, which can obstruct the passage of sound and may lead to various symptoms, including hearing loss, discomfort, or a feeling of fullness in the ear. Overproduction of cerumen or barriers to its normal drainage can lead to this condition. The wax can become hard and lodged in the ear canal, requiring removal for relief and to prevent complications.

In contrast, otitis media involves inflammation or infection of the middle ear, often resulting in fluid build-up, but does not specifically refer to wax accumulation. Cholesteatoma is an abnormal skin growth that can occur in the middle ear and is not directly related to wax accumulation. Tympanic dysfunction typically refers to problems with the tympanic membrane (eardrum) or its function rather than wax issues. Therefore, cerumen impaction specifically pertains to the excess wax situation described in the question.
