Hearing is the second most important sense organ after vision. The hearing organ enables cognition, communication with others and perception of the beauty – to hear the singing of birds and the sound of rain, to get acquainted with the street musicians’ performances and enjoy the world music masterpieces. Hearing helps us navigate the surrounding space and warns us of danger. There are many interesting facts on this sense organ in the world. For example, in some insects, such as crickets and grasshoppers, the hearing organs are located on the front legs; elephants have the ability to perceive sounds not only with their ears but also with their trunk and columnar legs – this is how they learn about the approach of an enemy or a herd of relatives. Human ears can grow throughout life, and the right ear is “exploited” four times more often than the left. The laryngoscope, a special tool for examining the larynx, was not invented by an ENT doctor but by a musician, Manuel Garcia, even though it was first used thanks to a doctor and scientist from Budapest, Jan Cermak, in medical practice. It is him who is regarded as the founder of modern otorhinolaryngology, the science that studies the ear, throat and nose diseases.
