Ear injuries sustained in bite or knife injuries often result in a partial amputation of the ear. Serious road traffic accidents can result in the loss of the entire ear. Major burns can also cause terrible injury to the ear. More minor deformity can result from infected piercings, particularly when the ear is pierced through the cartilage of its upper pole. Piercings can also split an earlobe and earlobe expanders can result in deformity that can only be corrected with surgery.
Surgery follows the principles of reconstruction for microtia, with establishment of a resilient ear framework and coverage with a thin soft tissue envelope, being prerequisites to a high quality reconstruction.
