fülzsír

Fülzsír, scientifically known as cerumen, is a natural secretion found in the ear canal of humans and many other mammals. It is produced by sebaceous glands and ceruminous glands located in the outer third of the ear canal. The primary function of fülzsír is to protect the ear. It traps dust, dirt, and other foreign particles, preventing them from reaching the eardrum. Fülzsír also contains antibacterial and antifungal properties, which help to ward off infections. Its waxy texture lubricates the ear canal, preventing dryness and irritation.

The color and consistency of fülzsír can vary significantly among individuals, ranging from light yellow and dry to dark brown and sticky. This variation is largely determined by genetics. While fülzsír plays a vital protective role, excessive buildup can lead to impaction, causing symptoms such as hearing loss, tinnitus (ringing in the ears), dizziness, and earache.

The ear canal has a natural self-cleaning mechanism. Chewing and jaw movements help to move old fülzsír from the deeper parts of the ear canal outwards, where it dries and falls out or is washed away. For most people, regular cleaning is unnecessary and can even be harmful. Inserting cotton swabs or other objects into the ear canal can push fülzsír deeper, leading to impaction, or cause injury to the ear canal or eardrum. If there are concerns about fülzsír buildup, it is recommended to consult a healthcare professional for safe removal methods.
