Here is a question that has troubled ENT doctors for a long time: why do cockroaches and mosquitoes like to get into the ears in the middle of the night?
Do you know the answer?
Cockroaches like the taste of volatile fatty acids. In addition to fermented foods such as bread, beer, and cheese, this chemical is released, and human earwax also emits the smell of volatile fatty acids. The outer ear canal is narrow, warm and humid, and it also exudes a seductive fatty acid scent. At night, the human body often maintains a fixed posture, so cockroaches come in.
After the cockroach enters the external ear canal, many people will pluck it with their hands, dig with an ear spoon, and want to clip it out with a clip. In fact, these methods often drive them deeper into the ear canal. Our external auditory canal is a dead end, with the tympanic membrane blocking the external auditory canal and middle ear cavity. If the worms are rushed, they will not only scratch the skin of the external auditory canal and cause inflammation of the external auditory canal, but they may also break the eardrum and further cause otitis media.
Traditional headlamps often take multiple attempts to remove objects under direct vision, which can lead to external auditory canal injury and objects move deeper, making it difficult to remove objects. Compared with traditional methods, the diagnosis and treatment of external auditory meatus under the ear endoscope has obvious advantages, not only can clearly distinguish the type and shape of foreign bodies, but also you can observe the adjacent relationship between the object and the external auditory meatus and tympanic membrane, it assess the degree of damage to the external auditory meatus and tympanic membrane, observe the movement of objects in real time and adjust the use of the instrument, and it can be taken out at one time.You can add ear endoscope to your home medicine kit.
(1) External ear canal irrigation method: The external ear canal is rinsed with a warm 0.9% sodium chloride solution. However, it must be avoided in the following cases:
Patients who damage the tympanic membrane and cause perforation of the tympanic membrane, patients with vegetative foreign bodies in the external auditory canal are prone to swelling with water, and patients with multi-angled sharp foreign bodies, quicklime and other chemical reactions with water.
(2) Direct clamping method: Use a hook to pick up objects, or directly use knee-shaped forceps to clamp the objects in the patient's external ear canal. However, for pediatric patients who cannot cooperate with diagnosis and treatment or the surface of the object is too smooth, do not use this method to avoid pushing the object deep into the patient's external ear canal.
(3) Negative pressure suction method: For this method, the suction device used in the comprehensive treatment of otolaryngology in the hospital is generally selected, and the appropriate diameter of the suction tube is correctly selected according to the shape and size of the object in the patient's external ear canal.
In short, only through reasonable and correct diagnostic and treatment measures, the object in the external ear canal can be removed smoothly without causing damage. Ear otoscope is a very convenient and practical medical product. We recommend that you keep it at home.
