You have an impressive deformity. In order to answer your question I would like to see what the back of the ear and the scalp behind the ear looks like. If those areas are unpigmented, the pigmented skin can bevremoved (checked for cancer), and te ear cartilage burried under the normal skin r a few weeks allowing to adhere to the cartage. Once this happens the ear is lifted with its new pink skin and the back less visible portion of the scalp is covered with a skn graft. That not being possible the skin in front of th ear may be expanded gadfly with balloons and transferred in similar fashion a few weeks later. Toronto as many great Plastc surgeons. You may even try the Hospital for Sick Children which has a world wide reputation in our field.
Good luck
