Stretched piercings are probably as old as piercing itself. All modern extension methods have been used by indigenous cultures.
For enlarging a piercing there are various methods of different origins and for different purposes. The simple stretch the stitch channel is usually gradually every several weeks made millimeter steps to loosen the fabric and not on further enlargement tear. The expanded branch channel forms after removing the jewelry, but again after some time and to minimize the risk of tearing. The cutting of the channel, however, is painful and can only by another surgical procedure can be reversed.
Most stretching methods left no wound and properly conducted enlargements must not heal then, but just need a "rest period" before being further expanded. The extent permitted by elasticity and texture, body piercings can be brought to very large diameters. The greater and longer the piercing has been stretched, the smaller the diameter dimension after removal of the jewelry, which is also on the age and individual tissues of the carrier-dependent. Than average policy is said that the ear holes were stretched to eight to ten millimeters regress after removal of jewelry mostly whole again. Quickly expanded to include minor channels usually as slowly stretched channels. Excessive or improperly stretched piercings can cause irreparable damage. This can lead to scarring. Scar tissue is difficult to stretch. With larger diameters, both the jewelry and the branch canal to be cleaned regularly, as it can lead to increased Talgablagerung and odors.
