Administering drops to the ear is a common treatment in otolaryngology. They are often used during recovery from external ear disease, middle ear disease, or ear surgery. But with such a small ear hole, there are some tips on how to get the medication into the ear to its full effect. First of all, we need to know the four anatomical structures: the auricle, the ear screen, the external auditory canal, and the tympanic membrane. There is a small bump in the front of the ear called the ear screen, and the hole in the middle of the ear is the external auditory canal, which is closed by the eardrum. To simplify it, the normal 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 the ear drops at the opening of the outer ear canal and put them in. Be careful not to let the mouth of the 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 if the drops are put into the ear, and people may get dizzy. After the drops, you should rub the ear screen because if you don’t rub the ear screen, there will still be air bubbles in the innermost part of the external ear canal, which will not have a therapeutic effect. After rubbing the ear screen, lie on your side for 5 to 10 minutes to give your ears 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 in the outer ear canal will flow out, which is a normal phenomenon.
