A very deep piercing that passes beneath the collarbone, and therefore enters the body cavity. These are highly prone to rejection as the collarbone placement is a high movement area. Also, because of the depth of the piercing—going deep under the collarbone and through a large amount of flesh and muscle—healing is difficult. With all the movement in the area the fistula cannot heal properly, and will hurt far worse than a hip piercing.

A deep chest piercing is a long piercing that passes under the skin of the chest and may be several inches long.

An eyeball implant, or extraocular implant, is a cosmetic implant involving a tiny piece of decorative jewelry which is implanted within the superficial, interpalpebral conjunctiva of the human eye (the covering of the white of the eye, in the area that is normally visible between the eyelids). Such implants are illegal in the United States.

A flesh staple is a type of piercing jewelry or implant in which the middle rather than the end of the jewelry is exposed when worn. The jewelry resembles a staple, the ends of which pierce the skin and hold the item in place.

A flesh plate works on the same principle, but has a different shape, resembling a flat plate rather than a staple.

Flesh pocketing resembles flesh stapling, but instead of staple-like geometry, small "pockets" under the skin hold the ends of the jewelry in place. Pocketing has a lower rate of success than stapling.
