Microtia is a term referring to a significantly malformed, poorly developed external ear. While it is relatively uncommon, it appears to be more prevalent in Central and South America than in North America. Both genetic and environmental factors are thought to play a role in the development of the anomaly, though a specific genetic marker has not been found. The severity of microtia can vary from case to case.
It can take three to four separate surgical procedures over a coarse of a year or longer to complete the transformation. The first stage is the longest and probably most complicated. It involves creating the auricular framework with rib cartilage. The second stage, lobule (earlobe) transposition is performed at least two months after the first stage. The third stage involves elevating the auricular framework which was created in stage one. The fourth stage involves constructing the tragus. The outcome from these procedures are remarkable and the smiles on the individual face’s say it all.
