If it is a movable insect foreign body, use oil to drop it into the ear, and then remove it with tweezers by adhering to the insect, and if it is a spherical foreign body, such as a glass ball, it is often used to remove it by right-angled curved hooks or suction tubes. 1. Active insect foreign bodies: because most insects can not crawl backwards or rotate in the external auditory canal, resulting in uninterrupted crawling towards the eardrum, so it is appropriate to use oil, ethanol and other drops into the ear, or ether-soaked cotton balls placed in the external auditory canal for a few minutes, the insect will be adhered to, anesthetized or killed, and then removed with tweezers or rinsed and discharged. 2. Hard spherical foreign bodies: for example, glass balls, beads, etc. may be difficult to remove because they are not easy to grasp, and it is common to use a right-angled hook to cross the foreign body or use a large straw to suck the foreign body to take it out. If the foreign body is large and tightly embedded in the deep part of the external auditory canal, it needs to be taken out under local anesthesia or general anesthesia. There are other types of foreign bodies in the ear, the removal method is also different, regardless of which type of foreign body, the foreign body into the ear must be dealt with in a regular hospital, do not operate on your own, so as not to cause greater damage.
