[This list contains text that some may not consider family friendly] Many of us have had piercing in the ears and probably quite a number of us have piercing in other less common parts of the body, but there are some people who have outright bizarre piercing and other body modifications. It was certainly not an easy task to find “safe” pictures for this list - but I have done my best!
Human branding is the process in which a mark, usually a symbol or ornamental pattern, is burned into the skin of a living person, with the intention that the resulting scar makes it permanent. This is performed using a hot or cold iron. It therefore uses the physical techniques of livestock branding on a human.
A subdermal implant refers to a kind of body jewelry that is placed underneath the skin, therefore allowing the body to heal over the implant and creating a raised design. Many people who have these implants use them in conjunction with other types of body modification to create a desired, dramatic effect.
Most people can stretch to at least 2ga (1/4″) and still have the tissue return to normal when they remove the jewelry, but there really are no guarantees. Don’t stretch your ears unless you are certain you’ll be okay with it forever. Once the elastic limit of the skin has been passed, or a large amount of additional tissue has been built up, the hole will not close again completely. A person who is either obsessed with stretching their piercings, or with showing off their many stretched piercings, is known as a “Gauge Queen”. Some wear this term with pride, others use it derisively.
Tongue bifurcation, or tongue splitting, is a type of body modification in which the tongue is cut centrally from its tip part of the way towards its base, forking the end. In most cases, the split is created through scalpeling or surgical laser. Self modifiers often choose to achieve a split by gradually tightening nylon bindings inserted through an existing tongue piercing over a long period of time. This method is long, arduous, and requires a high pain tolerance.
Tooth filing is a form of body modification in which people file their natural teeth to create a desired look or shape.
Also called corset training and waist training, this is the practice of wearing a tightly-laced corset to achieve extreme modifications to the figure and posture and experience the sensations of a very tight corset. Those who practice tightlacing are called tightlacers. Some tightlacers call the corsets they wear training corsets.
This is the practice of permanently inserting small beads made of various materials beneath the skin of the genitals–of the labia, or of the shaft or foreskin of the penis. As well as being an aesthetic practice, this is usually intended to enhance the sexual pleasure of partners during vaginal or anal intercourse. The practice seems to have been fairly common across world cultures and is still done today. You can see a VERY Not Safe For Work image here.
Eyeball tattooing has been around for a long time; in the 19th century it was commonly used to correct cosmetic defects in blind eyes. The procedure can be performed with traditional tattoo needle or a syringe. The eye is simply held open while the pigment, which is the exact same type used in a regular tattoo, is injected into the eyeball.
The process of anal stretching is a lot like earlobe stretching, except you don’t wear the “jewelry” around the clock. Like stretching a piercing, it involves slow and increasingly larger play over an extended period of time. The image above is for “tools” to aid in this modification.
The implantation of jewelry in the outer layer of the eye, this is one I must admit I had not heard of. Apparently first done in the Netherlands, it has come to the US. According to Dr. Christopher Rapuano, a corneal surgeon at Philadelphia’s Wills Eye Hospital, “You can think of it as crazy. I mean this is invasive surgery where you are cutting the surface layer of the eye open to put a little piece of jewelry in. The first time I read about this I said, ‘Oh, my God, who is doing this?’” The safety of this procedure will have to prove itself over time, since it hasn’t been performed on many people, but the possibility for infection and complications is definitely there.
James Sooy and Oliver Gibson have come up with Pierced Glasses - the most minimalist eyewear since the Pince-nez was invented in the 1840’s. I would not have believed this one if I had not seen it with my own bespectacled eyes.
Notable omissions: penis splitting (try finding a SFW image for that!)

10大不可思议的身体改造
（这张列表中可能存在某些不受家庭欢迎的内容）我们中的之中很多人都打有耳洞，也许很大一部分人还在身体不常见的地方穿了孔，但是有些人在穿孔和对身体改造方面的举动却是极其怪异的。虽然给这张列表配上一些适宜的图片绝对不是一件简单的事情，但是我已经尽我所能了。
人类烙印是指在人体的皮肤上灼烧出一个印记，或是一个点缀图案，这样结痂后，伤口便能使图案永久的留在皮肤上了。一般我们会选用炙热的铁块或是极度冰冷的铁块。因此在烙印时，我们就像给牲畜烙印一样给人烙印。
皮下植入是指将可以佩戴在身体上的珠宝首饰植入皮下，当伤口愈合时，使其成为身体的一部分并形成凸起的图案。为了达到一个期望中奇特的效果，很多人在皮下植入的同时还会进行其他身体改造。
很多人将自己的耳垂扩张到2毫米（1/4"），但是当他们脱下饰品的时候，肌肉组织还可以恢复原样，当然世事无绝对。除非你永远都不介意，否则不要去扩张你的耳垂。一旦皮肤失去了弹性，亦或是生成了更多的肌肉组织，那洞就永远都不会闭合了。如果一个人疯狂迷恋扩张又或是喜欢炫耀他们身上的穿孔，这样的人都被称为"Gauge Queen " 。有些人觉得这个称号是种荣誉，而另些人则相反。
舌头分歧，或者舌头分裂术是身体改造的一种，就是从舌尖开始，沿中间朝舌根方向将舌头切开。大多数的案例中，都是用解剖刀或是外科激光来实现切割的。但是也有人选择自己完成这个过程，他们先在舌头上穿孔，再用一根尼龙绳子穿过这个孔并逐渐收紧，这是一段很漫长艰辛的过程，需要很强大的毅力。
牙齿打磨也是一种身体改造，人们将牙齿磨成他们期望的样子和形状。
有时也称为塑腹训练或是腰部训练，这需要通过穿塑身衣来感觉塑身衣的紧致并达到极致的身体改造。塑腰的人被称为tightlacers，他们所穿的塑身衣就是训练塑身衣。
穿珠是指将不同材质的小珠子永久得嵌入阴茎或是外阴的皮肤里，又或者是男性生殖器的主要部分和包皮下。这不仅是一种美化，在性交或是肛交的时候更能增加彼此的快感。这项身体改造在全世界都是已经广为流传，并直到今天还有人在做这样的改造。点击这里有更多图片。
眼球文身已经流传了很长时间了，早在19世纪，还曾被用来改善化妆品会弄瞎眼睛的缺点。整个过程可以用针或是注射器完成。颜料也是一般纹身的颜料，在将颜料注射进眼球时，眼睛始终保持张开状态。
肛门扩张就如同耳垂扩张一样，唯一不同的是你不用整天带着饰品。像扩张一个穿孔一样，整个过程很慢，要经过一段很长的时间才能变得更大。上图就是此项改造的工具。
这就是指将饰品植入眼睛的外圈部分，我不得不承认我从前对此是闻所未闻的。它起源于荷兰，现在显然已驻足美国。根据费城Wills眼科医院的眼膜医生Christopher Rapuano说，“这真的很疯狂。我是说这是一项很有侵略性的手术，切开眼球的表面，再将小饰品植入。当我第一次听说的时候，我说‘天啊，谁会接受这个？’”。由于还没有很多人接受这样的手术，只有让时间来证明它的安全性了，但是感染和并发症的可能性还是存在的。
James Sooy 和 Oliver Gibson 提出了眼镜植入，这是自从1840年 Pince-nez 的诞生后最小的眼镜了，要不是我亲眼看到，我简直不敢相信。
