There are various nasal measurement parameters for rhinoplasty, so it is difficult for surgeons to decide which measurements to place more emphasis on. Among many, we searched for measurements that are significantly altered after the augmentation rhinoplasty with nasal tip plasty to figure out which measurements are most required in preoperative preparation. From January, 2006 to July, 2008, a total of 85 patients underwent augmentation rhinoplasty with nasal tip plasty and 40 were selected for comparative analysis of preoperative and postoperative photographs. Among many measurement factors reflecting changes of a face and a nose, we measured and compared following parameters, 1) nasofrontal angle, 2) nasofacial angle, 3) nasolabial angle, 4) nasal tip angle, 5) columella-lobular angle, 6) nasal length to tip projection, 7) alar slope angle, 8) nostril axis angle, 9) lobule-to-nostril ratio before and after operations. The result was analyzed using paired t-test. The measurement parameters most significantly altered after augmentation rhinoplasty with nasal tip plasty were the increase in nasolabial angle, the decrease in nasofacial angle, and the decrease in nostril axis angle. Therefore, surgeons should place more emphasis on these parameters in preoperative planning and postoperative evaluation.
