What can happen if cerumen builds up in the ear canal?

When cerumen, commonly known as earwax, builds up in the ear canal, it can lead to conductive hearing loss. This occurs because the excessive accumulation of cerumen can obstruct sound waves from properly reaching the eardrum. When sound waves are impeded, they cannot effectively transmit vibrations to the inner ear, resulting in a reduction of sound perception and clarity.

Conductive hearing loss is characterized by a decrease in sound intensity and can occur as a result of physical obstruction, infection, or fluid in the ear. In the case of cerumen buildup, the degree of hearing loss can vary depending on the amount of earwax present and the extent to which it blocks the ear canal. Proper cleaning and management of cerumen can help alleviate this condition and restore normal hearing function. This understanding highlights the importance of maintaining ear health and monitoring for signs of excessive earwax buildup.
