What are common changes in the ear canal due to aging?

As individuals age, it is common for the ear canal to undergo various changes. Skin dryness and itchiness are prevalent symptoms. This is primarily due to a decrease in the production of natural oils in the skin, which can lead to drier skin overall, including in the delicate skin of the ear canal. The lack of moisture can make the skin more prone to irritation and discomfort, which manifests as itchiness.

The skin in the ear canal can also become thinner and less elastic with age, further contributing to these sensations. It is essential for hearing instrument specialists to recognize and address these changes when fitting hearing aids or providing care, as they can affect the overall comfort and effectiveness of hearing devices.

While the other options also reflect various characteristics associated with hearing and the ear canal, they do not specifically highlight the common changes brought on by aging as effectively as the change in skin condition does. For instance, earwax may become drier and harder rather than softer, and aging does not typically lead to an extended ear canal length nor heightened sensitivity to sound as a direct consequence of aging.
