Medical surgery leagues.
Medical plastic surgery league is a group of medical students interested in plastic surgery and a professional volunteer in the area willing to share and produce knowledge. Students define their direction, and are coordinated by an board certified plastic surgeon. Students should be aware that the league is an opportunity to learn, to seek knowledge, to develop clinical and scientific reasoning, and stimulate its interaction with the community. It means strengthening and enhancement of expertise in different levels of learning. Even if they do not become plastic surgeons, students build skills that can be adapted to other conditions and situations in the future.
