The auricle and the external auditory canal form what is known as the external ear.

The two structures of the outer ear are used to pick up the sound (auricle) and its transmission (external auditory canal) to the inside adjacent eardrum.

In order to be able to fulfill these functions, nature intended that there be a direct connection between the auricle and the external auditory canal.

This is important because inflammations that supposedly affect the visible auricle often have their real origin in the area of the non-visible ear canal. However, inflammation confined to the auricle can also occur.

The cause of a also that Earlobe relevant inflammation is common bacterial in nature. Because the earlobe in contrast to the auricle no cartilage possesses, this is a skin infection, the so-called Eryspiel.

You can also Chickenpox Virus cause inflammation in the area of the auricle. The infection can start again if the patient has not yet had chickenpox or if there is insufficient defense against the virus. However, it is also possible that for reactivation, i.e. to activate viruses that were previously dormant. These viruses remain in the body after having had chickenpox and can be particularly dangerous if the immune system is weak cause symptoms again. The resulting disease is then called Shingles (Zoster) designated. The shingles of the ear is called Herpes zoster oticus.

Both non-infectious causes stand the Contact eczema in the foreground. This type of inflammation can be caused by a allergic reaction, that is, a hypersensitivity reaction.
