This ear reconstruction video shows a surgery to correct microtia by Toronto Plastic surgeon, Leila Kasrai MD. Microtia means small ear, and it is a congenital abnormality which causes problems with the formation of the ear tissue. In some children, a small portion of tissue is seen where the ear would normally be found. In others, the ear lobe or hollow of the ear, may be partially formed with the rest of the ear tissue missing. The most severe form of this condition leaves almost no ear tissue visible.
