PIERCING GUNS CAN CAUSE SIGNIFICANT TISSUE DAMAGE.
Though slightly pointy in appearance, most ear piercing studs are quite dull. Piercings must therefore be accomplished by using excessive pressure over a larger surface area in order to force the metal shaft through the skin. The effect on the body is more like a crush injury than a piercing and causes similar tissue damage. Medically, this is referred to as “blunt force trauma.” At the least, it can result in significant pain and swelling for the client, at the most in scarring and potentially increased incidence of auricular chondritis, a severe tissue disfigurement.
Occasionally the intense pressure and speed of the gun’s spring-loaded mechanism is not sufficient to force the blunt jewelry through the flesh. In these cases, the earring stud may become lodged part way through the client’s ear. The gun operator, who may not be trained to deal with this possibility, has two options. S/he can remove the jewelry and repierce the ear, risking contamination of the gun and surrounding environment by blood flow from the original wound. Alternately, the operator can attempt to manually force the stud through the client’s flesh, causing excessive trauma to the client and risking a needlestick-type injury for the operator. How often such gun malfunction occurs has not been documented by manufacturers, but some gun operators report that it is frequent.
When used on structural tissue such as cartilage, more serious complications such as auricular chondritis, shattered cartilage and excessive scarring are common. Gun piercings can result in the separation of subcutaneous fascia from cartilage tissue, creating spaces in which fluids collect. This can lead to both temporary swelling and permanent lumps of tissue at or near the piercing site. These range from mildly annoying to grossly disfiguring, and some require surgery to correct. Incidence can be minimized by having the piercing performed with a sharp surgical needle, which slides smoothly through the tissue and causes less tissue separation. A trained piercer will also use a post-piercing pressure technique that minimizes hypertrophic scar formation.
Cartilage has less blood flow than lobe tissue and a correspondingly longer healing time. Therefore infections in this area are much more common and can be much more destructive. The use of non-sterile piercing equipment and insufficient aftercare has been associated with increased incidence of auricular chondritis, a severe and disfiguring infection in cartilage tissue. This can result in deformity and collapse of structural ear tissue, requiring antibiotic therapy and extensive reconstructive surgery to correct. Again, medical literature has documented many such cases and is available on request.
THE LENGTH AND DESIGN OF GUN STUDS IS INAPPROPRIATE FOR HEALING PIERCINGS.
Ear piercing studs are too short for some earlobes and most cartilage. Initially, the pressure of the gun’s mechanism is sufficient to force the pieces to lock over the tissue. However, once they are locked on, the compressed tissue cannot return to its normal state, is constricted and further irritated. At the least, the diminished air and blood circulation in the compressed tissue can lead to prolonged healing, minor complications and scarring. More disturbingly, the pressure of such tight jewelry can result in additional swelling and impaction. Both piercers and medical personnel have seen stud gun jewelry completely embedded in ear lobes and cartilage (as well as navels, nostrils and lips), even when pierced “properly” with a gun. This may require the jewelry to be cut out surgically, particularly in cases where one or both sides of the gun stud have disappeared completely beneath the surface of the skin. Such consequences are minimal when jewelry is custom fit to the client, allows sufficient room for swelling, and is installed with a needle piercing technique which creates less trauma and swelling.
Jewelry that fits too closely also increases the risk of infection because it does not allow for thorough cleaning. During normal healing, body fluids containing cellular discharge and other products of the healing process are excreted from the piercing. But with inappropriate jewelry, they can become trapped around the hole. The fluid coagulates, becoming sticky and trapping bacteria against the skin. Unless thoroughly and frequently removed, this becomes an invitation to secondary infection. The design of the “butterfly” clasp of most gun studs can exacerbate this problem. Again, these consequences can be avoided with implant-grade jewelry that is designed for ease of cleaning and long-term wear.
