Under normal circumstances earwax should be pale yellow with no special smell, but clinically some patients, for example, because of their personal constitution, can also lead to the appearance of other smells. Some patients, for example, often eat large, oily, greasy, body sebaceous glands secrete very vigorously, and due to the presence of sebaceous glands and cerumen glands in the ear canal, the patient’s ear canal sebaceous glands secrete a lot of oily substances, and cerumen mixed together, resulting in the patient’s earwax The patient’s earwax has a special oily aroma. This can be observed clinically, but if it is itchy or painful, it should be cleaned up promptly because earwax containing too much oil can easily be oxidized to black in the air, which can easily induce inflammation of the ear canal and lead to ear pain and other related discomfort. This kind of earwax is not easily discharged clinically on its own and can easily block the ear canal, leading to hearing loss and other discomforts.
