Reconstruction Pinna is a surgical procedure performed to treat underdeveloped ear at birth and loss of normal ear due to trauma, disease, or an accident. The procedure is performed in two stages that are about 6-12 months apart. Stage 1 of Pinna Reconstruction involves creating a skin pocket at the site of the ear by reshaping the available tissue and thinning the skin to mimic the ear skin. Stage 2 involves putting the new ear in position so it sticks out from the head like a normal ear. This is achieved by lifting it into place with a piece of cartilage behind it to support its position.
