A masculine chin tends to be taller, wider and has more of a square shape, while a feminine chin tends to be shorter, narrower and more rounded. Many people think feminine chins are V-shaped, but on average, they are actually U-shaped.
Men’s chins also protrude forwards a little more than women’s, but I don’t think that chin projection is as important as the size and shape of the chin when it comes to gender recognition.
1. Height and Shape:
Chin corners can usually be removed by burring and/or cutting the bone.
If the chin needs to be reduced in height, most surgeons will cut a section of bone off the bottom, but some still use an older technique where they remove a horizontal section of bone from the middle of the chin and then close the gap.
One reason sometimes given for using the older technique is that you don’t have to detach the muscles from the chin bone in order to shorten it because they remain attached to the lower section that you are no working on, but that also means you can only change the height of the chin and not the shape of the lower section, and in most FFS cases, you need to change the shape too.
2. Receding Chin:
A receding chin is not really a masculinity or a femininity – it is mainly a beauty issue, and that means it’s down to your personal taste whether or not you like it, but if you are having a feminising genioplasty, you can take advantage of the incisions to have the chin moved forwards at the same time.
There are 2 ways of moving the chin forwards. One is to move the chin bone itself. This is called a “sliding genioplasty”. The advantage with this technique is that it doesn’t involve implants, but if it is not done properly, it can leave an indented area on either side of the jaw behind the chin. The other technique is to add an implant. This is simpler, but there are potential complications associated with implants – for example they can slip, they can become spontaneously infected even years after they were put in, and they can wear down the bone they are sitting on. For those reasons, I usually recommend a sliding genioplasty rather than an implant.
An added benefit of moving the chin forwards is that it tightens up the soft tissues under the chin, and that helps to prevent any slackness in the tissues caused by chin or jaw reduction.
Sometimes the issue is not a receding chin, but an underdeveloped lower jaw, when the jaw itself has failed to bring the chin forwards enough. However, on this page I am only talking about a situation where the jaw is normal, but the chin itself lacks projection.
3. Projected Chin:
Some people have a chin that projects forwards much more than average. As with a receded chin, this is more of a beauty issue than a femininity issue, but it is possible to remove bone from the front of the chin, or slide the chin backwards in a sliding genioplasty to reduce the chin projection. One downside of reducing chin projection is that it can cause more slackness in the soft tissues, so I don’t generally recommend it unless the chin projection is severe enough to have an obviously detrimental effect.
4. Fat Under the Chin:
There is a pocket of fat under the chin called the “submental fat pad”. It’s not a femininity issue and everyone has one, but it can vary a lot from person to person, with some people naturally having more fat in this area than others.
The most common cause of a very large submental fat pad is being overweight, and in that case, the ideal solution is to lose weight. However, weight loss is not always possible, and some people have an excess of fat here despite not being overweight. In those cases, liposuction under the chin is a way of reducing it.
5. Slack Soft Tissue Under the Chin:
A similar problem to fat under the chin is excess skin under the chin, and again, it’s not really a femininity issue – it’s usually something you develop with age. The only way to fix it is with a neck lift. However, it is important to have any lifting done several months after chin and/or jaw surgery, and not before or during.
6. V-Line chin surgery:
V-line chin surgery involves taking a vertical section of bone out of the centre of the chin, then bringing the sides together to close the gap. The idea is to narrow the chin strongly and give it a V shape. Many people think this is a particularly powerful technique that allows for greater changes than other techniques, however, you can achieve the same result by removing bone from either side – basically, it’s the position of the nerves that limits the amount of change, rather than the particular technique.
Also, it’s important to understand that typical feminine chins are U-shaped rather than V-shaped.
7. Labio-mental fold reduction:
The “labio-mental fold” is the horizontal crease between the chin and the bottom lip. If you feel that yours is too deep, you can have it reduced. This can be done with an injectable filler or even by adding a small bone graft during chin surgery in some cases. This is a cosmetic treatment and has no particular effect on femininity.
