How Are Chin Reductions Performed?

I find it difficult to find plastic surgeons who have experience with this type of procedure. Chin augmentation seems more common than reduction itself.

I'd like to know what was done to this patient, because it is really semiliar to me. The patient photos- http://www.facesplus.com/before-after/facial-procedures/chin-reduction/
