The external ear consists of the external auditory canal, also known as the external acoustic meatus, and the auricle. The external ear canal extends from the auricle to the lateral surface of the eardrum. A characteristic S-shaped structure, it is responsible for collecting sound waves and conveying them to the eardrum.
One of the most important functions of the ear canal is to filter out harmful particles. Together with the auricle, it detects sound waves and directs them towards the tympanic membrane. The external auditory meatus, however, does not allow humans to hear certain frequencies, such as infrasound and ultrasound, but only frequencies between 20 Hz and 20,000 Hz.
Among the pathologies of the external auditory canal, the earwax plug, caused by an excessive accumulation of secretion from the ceruminous glands, is the most common. In addition, ear canal dermatitis can cause itching, peeling, and erythema of the skin surrounding the ear canal. Contact eczema can also affect the ear canal, causing itching. The external acoustic meatus can be affected by bacterial infections as well, so it's crucial to keep it clean.
Inflammation, which often causes hearing loss, can be prevented by cleaning the ears thoroughly. But how do you do it? The removal of earwax buildup can be facilitated by a variety of treatments. Among them are ear sprays, syringe washing, drops for ear wax, and aspiration procedures for ear wax. Take the time to clean your ears regularly to keep them healthy.
