Sodium bicarbonate and phenol ear drops are often used to soften ear wax. Earwax is a substance secreted by the cerumen glands in the external ear canal and is relatively soft and easy to remove in normal conditions. However, in some patients, the cerumen glands are more vigorous and secrete more earwax, which can easily accumulate in the external ear canal and form a very hard ear stare for a long time, which needs to be softened with drops. After softening, you can go to the hospital for external ear canal rinsing or remove the earwax with a suction device. It is not recommended to pull out your own ear at home to avoid damaging the external ear canal and eardrum. Some people have sticky earwax that does not come out easily. This is called oily earwax and needs to be softened with phenol ear drops. Phenol ear drops also have anti-inflammatory and pain-relieving effects for tympanitis and acute otitis media, but should not be used if the eardrum is perforated to prevent burning of the middle ear tympanic chamber mucosa and causing congestion and edema in the tympanic chamber. Since too much earwax can cause embolism and symptoms such as tinnitus, ear congestion and ear pain, you need to go to the hospital for cleaning in time.
