The article is partly a tribute to Dr. Paul Tessier who trained Dr. Ousterhout and mostly a description of techniques use to masculinize the face. So far, the author has only performed facial masculinization on six men, but he has performed some of the individual techniques involved many times.
The article discusses the various techniques used and some of the possible complications. There are good before and after photos – the person is posed the same way. I can easily see the differences in the faces. The faces are more masculine after surgery, but they were also clearly men’s faces before surgery.
Chin masculinization has sometimes resulted in facial numbness that is usually temporary, but there have been cases where it was not. The author says he has reduced this problem over time.
As in most of this research, the study is written by the person who performed the operations and might therefore be biased in favor of the work.
