Putting drops in the ear is a common treatment in otolaryngology. They are often used after external ear disease, middle ear disease or ear surgery. But with such a small ear hole, how do you get the medication into the ear to effectively treat the disease? First of all, we need to know four anatomical structures: the auricle, the ear screen, the external ear canal, and the tympanic membrane. There is a small bump in front of the ear called the ear screen, and the hole in the middle of the ear is the opening of the external auditory canal, which is closed by the eardrum. To simplify it, the external auditory canal is a tube that is open at one end (the auricular end) and closed at the other (the tympanic end). First, find a comfortable position, lie on your side or tilt your head sideways, in any case, let your ears face upwards! Then, aim at the opening of the external ear canal and put the medication in. Be careful not to let the mouth of the medication bottle come into contact with the outer ear canal, as this will contaminate the medication. Remember to keep the medication warm before you put the drops in, otherwise the medication will be too cold and the vestibular system will be stimulated and people will get dizzy if the drops are put into the ear. After the drops, you should rub the ear screen because if you don’t rub the ear screen, it will look like this: There are still air bubbles in the innermost part of the external ear canal, so it doesn’t play a therapeutic role. After rubbing the ear screen, it looks like this: After rubbing the ear screen, lie on your side for 5 to 10 minutes and let your ears take a comfortable bath. Then get up and do what you need to do. When you get up, the outer ear canal will turn from vertical to horizontal, and some of the medication will flow out of the outer ear canal, which is normal.
