Ceruminous deafness, also known as conductive hearing loss, is a condition that occurs when there is a blockage or buildup of cerumen, commonly referred to as earwax, in the ear canal. This obstruction can lead to muffled sounds or difficulty hearing altogether. Synonyms for ceruminous deafness include conductive hearing impairment, earwax blockage-induced hearing loss, and cerumen-related hearing difficulties. Regardless of the term used, it is vital to recognize and address ceruminous deafness promptly. Seeking medical attention from an audiologist or an otolaryngologist can help in the removal of cerumen and restore normal hearing abilities.
