Some patients feel ear pain after surgery. They originally thought that it was the post-operative recovery period, when the wound was healing and pain from the wound was inevitable. However, after a period of time, there is still ear pain and ear congestion. Chronic suppurative otitis media often damages the eardrum, so the first problem addressed by surgery is repairing the eardrum. But in fact, for some patients whose eustachian tube is also not functioning well, just repairing the eardrum is far from enough. The eustachian tube is an important channel for balancing the pressure inside and outside the tympanic chamber. If the eustachian tube is still unable to regulate the pressure inside and outside the tympanic chamber after surgery, the pressure outside the tympanic chamber will be greater than the pressure inside the tympanic chamber, creating a relative negative pressure in the middle ear, which will cause ear pain and stuffiness. Of course, inflammation in the middle ear that has not been adequately cleared may also cause ear pain. So what can be done to promote the recovery of eustachian tube function after surgery? There are two ways, the first is to pinch and puff the nose, and the second is to blow up a balloon. Basically, patients can do it at home. Moreover, in order to protect the eardrum after surgery, special attention should be paid to blowing the nose. If both nostrils hold the air together to blow the nose, it will create a huge air pressure in the nasopharynx, and in case of dysfunction of the eustachian tube, the huge air pressure will reach the middle ear through the eustachian tube. This causes great pressure on the eardrum, which is still in the process of repair, thus affecting the repair of the eardrum, and in addition, it may lead to the displacement of the implanted auditory bone. Therefore, when blowing your nose after surgery, you should do it one nostril at a time to prevent huge pressure on the middle ear. Similarly, the same applies to sneezing, which should be done with an open mouth. Not only that, the airplane takeoff and landing process also has a great impact on the eustachian tube, and it is generally not recommended to fly within one month after surgery. In terms of diet, try to eat soft food and keep bowel movement smooth to prevent dry stools. Do not smoke and drink after surgery, as tobacco and alcohol have a great impact on the recovery of the eustachian tube. It is also important to avoid upper respiratory tract infections so that nasopharyngeal secretions do not block the pharyngeal opening of the eustachian tube.
