Is my chin implant too big? Should I consider removal? (Photos)

They are appealing: quick surgery, cheap, outpatient management and veeery easy technical for the surgeon, even the less skilled and experienced can do them, however they have very bad downsides, in practical terms they have short duration due to pain, displacement, visibility, mobility, weird gestures, failing to achive goals, etc, and I mean this about silicone, medmore and any other material used for them.

You have microgenia, this is small bone developtment at the chin, therefore you need chin augmentation with bone supply (iliac grafting); not a case for sliding genioplasty giving there's nothing to slide, it is primery deficit of bone substance.

True that such a revision genioplasty is tricky, complex and need lots of experience and talent, among other goals the mentalis nerves have to be spared (routine maneouver) and the mentalis tendon be reattached to the bone surface via trans-osseous drilling (also routine).

In females, large implants often give the chin a wider appearance and can look masculine. The amount of projection is fine but less width would be more feminine. In cases similar to yours, I remove the implant and perform a sliding genioplasty. This allows me to center the natural chin and keep the same width as before the implant. In addition, all the natural muscle reattach so that lip movement remains normal.
