fülnyílás

Fülnyílás, often translated as ear opening, refers to the external aperture of the ear canal. In anatomical terms, this is the meatus acusticus externus, the visible part of the outer ear that leads into the middle ear. The primary function of the fülnyílás is to collect sound waves and direct them towards the tympanic membrane, commonly known as the eardrum. Its shape and structure play a role in sound localization and filtering out certain frequencies.

The fülnyílás is lined with skin that contains specialized glands producing cerumen, or earwax. Earwax serves protective functions, trapping dust, debris, and microorganisms, and also helps to moisturize the ear canal. While the fülnyílás is a natural and essential part of the auditory system, it can be susceptible to various issues. Blockages, often caused by excessive earwax accumulation, can impair hearing and lead to discomfort. Infections, such as otitis externa (swimmer's ear), can also affect the fülnyílás and surrounding tissues, causing pain, inflammation, and discharge. Maintaining cleanliness by gently wiping the outer part of the fülnyílás with a soft cloth is generally recommended, while avoiding the insertion of sharp objects into the ear canal to prevent injury and impaction of earwax.
