Hair falling into the ear is more common in otology clinics, mainly causing itchy ears or irritation of the eardrum when the hair moves, resulting in a clattering or booming sound that causes ear discomfort and affects work and study. Because the hair is small, if it falls into the ear, it will stick to a certain location in the external ear canal and is not easy to remove. It is recommended to take it out at the hospital’s ear clinic, using tweezers under the direct view of the frontal mirror or tweezing it out under the in-ear mirror. If the hair is attached to the eardrum, do not use tweezers because there is a very high possibility of injury to the eardrum. The hair should be sucked out with a negative pressure suction device under the frontoscope or endoscope, or the external ear canal should be flushed out with saline, which will not hurt the tympanic membrane and will not cause tympanitis or tympanic membrane perforation.
