First-aid measures for ear worms are to irradiate the ear with light or to drop sesame oil into the ear, but it is best to go to the hospital immediately for professional examination. 1. Use light to irradiate the ear: most of the bugs in life have phototropic properties, when the ear accidentally into the bugs after the patient can first go to a darker place, and then use light to irradiate the ear, the bugs will be towards the light of the place to slowly move out of the ear. It is not recommended to use this method without specifying the type of bugs, such as some insects such as cockroaches, which will be backlit under this method. 2. Drop scented oil into the ear: the patient can turn his head sideways first, and his family or friends can pour the scented oil into the ear to restrict the movement of the insect; when the insect is observed to be motionless, the patient can turn his ear downward, and slightly vibrate the scented oil and the insect out of the ear together. The above two first aid measures are for use in daily life when the patient does not have professional equipment and is far away from a hospital. The best way is to go to a hospital immediately for examination and treatment. Doctors usually use a frontal scope to observe the bug. If the bug is on the outside of the ear canal, it can be removed with gun tweezers, and if it is on the inside, it can be removed under an otoscope. Patients should not use cotton swabs or ear spoons to pull out the ear after the bugs have entered the ear, so as to avoid the bugs from crawling deeper into the ear, leading to rupture of the eardrum and other serious consequences. After the ear worms into the patient should be treated in a timely manner, if there are symptoms of discomfort should be immediately sought medical treatment, so as to avoid irreversible damage.
