In order to evaluate the changes before and after secondary operations in the patients with cleft lip objectively using full face photographs, the author analyzed results of improvement on nasal width and mouth width and asymmetry of nostril. 1. The ration of asymmetry of thenostril is changed from average 1.24 preoperatively to average 1.08 postoperaively : 61.2% is improved postoperatively. 2. The ratio of nasal width compared with intermedial canthal distance is changed from average 1.15 preoperatively to average 1.10 postoperatively : 3.8% is reduced posteroperatively. 3. The ratio of mouth width compared with intermedial canthal distance is changed from average 1.08 preoperatively to average 1.03 postoperathvely : 4.1% is reduced posteroperatively.
