What is a foreign body in the external auditory canal? Theoretically, a foreign body in the external auditory canal is a foreign body in the external auditory canal. Common clinical foreign bodies in the external auditory canal include beans, stones, glass beads, small insects, etc. The Monkey King’s hiding of the golden rod, which is the size of an embroidery needle, in the external auditory canal can be said to be the only foreign body of its kind. Whether a foreign body in the external auditory canal causes clinical symptoms varies according to the nature of the foreign body and the duration of its retention. Small, nonirritating, nonbiological foreign bodies can remain in the external auditory canal for long periods of time without clinical symptoms, as was probably the case with the Monkey King’s Golden Cudgel. Insect-like animal foreign bodies can cause severe earache due to crawling and commotion, and can even make the patient panic. I have seen a patient, because the cockroach climbed into the external ear canal, the patient pain unbearable, one hand over the ear, “ah, ah” screaming ran to the hospital for treatment. A 6-year-old boy playing in kindergarten, learning the cartoon in the Monkey King will be the Golden Cudgel into the ears of the action, naughty a soybean into the external ear canal, did not expect that he did not have the Monkey King’s magical powers, soybean into easy to take out the difficult, the “little Monkey King” how to take out of his! This “little Wukong” couldn’t get his “golden rod” out. Later, the teacher found this situation, in time to send the child into the nearby hospital. Eventually, or otolaryngologists from the boy’s external auditory canal to remove the “problem” of the soybean. This time the Monkey King also got into trouble! In the future, the television station in the broadcast of the Journey to the West theme of the program, may have to declare that “children should not”. Otorhinolaryngologist reminds, because children are more curious, parents must teach children, do not put everything into the ear, mouth. In addition, the human external auditory canal is not a vertical channel, if placed in the ear canal foreign body, you should go to the hospital in time to let the doctor to remove the foreign body. If the foreign body is not removed in time, it may stimulate inflammation of the ear canal, and in serious cases, it may cause perforation of the eardrum, which directly affects hearing. In recent years, with the progress of science and technology and the increase of employment pressure, the types of foreign bodies in the external auditory canal have also undergone radical changes, before, we are common foreign bodies are beans, stones, glass beads, small insects, etc., but not now, now the external auditory canal foreign body has been changed to a new type of high-tech invisible headphones. Invisible headset is a highly sophisticated technology products, mainly for some not easy to expose, or can not expose the headset lead or the headset itself occasions, such as news unannounced visits, stage performances, television broadcasting, government high-level on-site lectures, criminal investigation and control, the protection of important people and entertainment venues applications, its portability, concealment can completely replace all wired headset! However, with the increasingly wide circulation of the product, some students take it to cheat, mainly to deal with the national English four, six level examination. So, what is the purpose of putting invisible headphones into the external ear canal? In fact, into the external ear canal is only invisible headset micro voice prompts, receiving range between 400-3000 meters. Before entering the examination room, the first only 3 millimeters in diameter headset (miniature voice prompts) into the outer ear canal, will be like a keychain the size of the host hanging in the waist or pocket, from the appearance of very difficult to be found. After the start of the examination, the transmitter outside the examination room with a well-tuned walkie-talkie to read the answer, their ears in the “small metal block” will receive the answer over. So, where do the correct answers come from? According to sources, after the examination paper, the examination questions leaked from the examination room, candidates do listening to the question, there will be a special division of labor to do the question, make the correct answer. Therefore, as long as the use of invisible headphones, you can pass the examination, is absolutely not worth promoting. By the way, after taking the exam, the invisible headphones should be taken out. If this kind of thing is stored in the ear canal for a long time and cannot be taken out, it may stimulate inflammation of the ear canal, and can even cause perforation of the tympanic membrane and decrease in hearing, which will lead to otitis media until deafness. However, their magical powers are not as vast as the Monkey King, can only put the “golden rod” into the ear, however, can not be taken out, have no choice but to turn to the doctor for help. For foreign bodies in the external auditory canal, “prevention is more important than treatment”, as a doctor, our advice is: (1) educate children not to put small objects into the external auditory canal; (2) adults should not use matchsticks or toothpicks to dig into the ear; (3) once a foreign body occurs in the external auditory canal, you should go to the hospital immediately and ask the doctor to take it out. Do not learn from the Monkey King, put the “golden rod” in the external ear canal, he is very powerful, not afraid of anything, you can?
