Alcohol drops are not allowed in the ears, and there is no practical significance to alcohol drops. The dangers of alcohol drops are as follows: 1. They may cause irritation to the deep part of the ear canal and the surface of the eardrum, causing painful sensations and other uncomfortable symptoms; 2. Some patients may themselves have long-term chronic purulent otitis media and have a perforated state of the eardrum for a long time, and alcohol drops are prone to enter the middle ear cavity directly, causing strong irritation to the middle ear mucosa and triggering severe pain. If the patient has some greasy cerumen secretions in the ear canal, you can use alcohol swabs to clean the ear canal appropriately, which can have a degreasing effect and can clean the ear canal relatively clean, but it is generally not necessary to put alcohol drops into the ear.
