Normally, there are no bugs in the ears. However, in summer, when it is hot, some people may sleep on the ground or in a tent when they go out for fun, and it is especially easy for crawling bugs or small flying insects to get into the ears. Sometimes patients can feel bugs crawling in their ears, or the sound of wings fluttering. The patient will have pain inside the ear that is more pronounced, and there will also be tinnitus, so it is important to visit the hospital in a timely manner. The doctor can apply alcohol or ether drops in the ear canal to first stop the worm from moving, and then remove the worm directly under the endoscope. Patients must pay attention to protect their ears, try not to sleep on the ground, pay attention to the sanitary environment at home, and sleep with earplugs in their ears when they go out to avoid unnecessary problems caused by worms in the ears.
