A new nose, grown by surgeons on Xiaolian's forehead, is pictured before being transplanted to replace the original nose, which is infected and deformed, at a hospital in Fuzhou, Fujian province, China, September 24, 2013. Xiaolian, 22, neglected his nasal trauma following a traffic accident on August, 2012. After several months, the infection had corroded the cartilage of the nose, making it impossible for surgeons to fix it leaving no alternative but to grow a new nose for replacement. The new nose is grown by placing a skin tissue expander onto Xiaolian's forehead, cutting it into the shape of a nose and planting a cartilage taken from his ribs. The surgeons said that the new nose is in good shape and the transplant surgery could be performed soon.REUTERS/Stringer
