Ear knots should be clinically referred to as cerumen. The exact way to get it out needs to be determined by the size and extent of the cerumen. If the cerumen is shallow and not much, you can clean it out by yourself using an ear scoop or cotton swab. If the cerumen is deep, large and clogging the external ear canal, you will need to use medication to soften it thoroughly before going to the hospital to clean it out.
The skin of the external auditory canal contains ceruminous glands, which have the function of secreting cerumen. Under normal circumstances, cerumen is in a dynamic equilibrium and has a protective effect on the external auditory canal, maintaining a slightly acidic environment to resist microbial attack.
1. If the amount of cerumen is shallow and small, you can use an ear scoop or cotton swab to remove it. Avoid digging too deep and damaging the tympanic membrane during the cleaning process.
2. If the cerumen is deep, large, hard and blocking the outer ear canal, medication is needed to soften it completely. 5% sodium bicarbonate can be used to soften the cerumen. After softening, the cerumen should be flushed out with warm saline, or cleaned under the direct vision of an otoscope with a cerumen hook or a suction device.
