Ear knots do not have to be removed. The so-called ear knots, commonly known as earwax, or cerumen of the external auditory canal in ear, nose and throat clinics, are a gradual accumulation of ceruminous gland secretions, necrotic epithelium, and metabolic products on the skin of the external auditory canal, and may be more likely to contribute to the problem, especially if one has the habit of pulling out one’s ears repeatedly. If the size of the ear knot is small, it will not produce obvious clinical symptoms. If the knot is large and blocks more than 1/2 of the ear canal, it can produce clinical symptoms of tinnitus, ear stuffiness and hearing impairment. If it swells with moisture after bathing or swimming in water, it may produce painful symptoms and further worsen the ear stuffiness. It is not necessary to remove the ear knot, and if the patient cannot cooperate well, it can also not be removed. At most, there will be tinnitus, ear stuffiness and hearing impairment, and there will be no other serious consequences.
