Ear piercing
Pierced ears have had one or more holes or "piercings" created in the earlobes or the cartilage portion of the external ears for the wearing of earrings. Piercings become permanent when the tract around the starter earring epithelializes during the healing period following the initial piercing, and are sometimes mischaracterised as a fistula. The piercings do not form fully if the starter earrings are removed prematurely, or if earrings are not worn in the piercings for a longer period, depending on the recency with which the ear was pierced.
