With a bug in the ear, patients are advised to go to the ENT department of the hospital in time. Removed by a professional doctor, patients should not dig themselves to avoid damage to the skin of the external ear canal or pushing the foreign body deeper. After the foreign body is removed, the outer ear canal should be kept dry and clean to prevent infection. Patients who have worms in their ears should not dig them out by themselves, and are advised to go directly to the hospital to have them removed. If it is an insect crawling or fluttering in the external ear canal, the doctor will first use non-irritating oil drops into the external ear canal to make the insect stick and not move in the ear canal before removing it. Insects entering the ear may lead to infection of the external ear canal. If the external ear canal is infected, you can follow the doctor’s instructions to use penicillin, cefazolin, piperacillin, and other medications for anti-infection treatment. At the same time, keep the external ear canal dry and clean.
