Mean age of the 38 patients was 25.53\(\pm\)4.08 years (range, 20 to 37 years), and there were 7 men (18.4%) and 31 women (81.6%).
The average nasal tip projection ratio was 0.85 ± 0.14 preoperatively and 0.97 ± 0.15 postoperatively (p<0.001). The average nasolabial angle was 90.79±9.33 preoperatively and 95.09±9.57 postoperatively (p<0.001), and these changes in nasal tip projection ratio and nasolabial angle were significant. Mean preoperative nasal tip location ratio was 1.89 ± 0.20, and mean postoperative nasal tip location ratio was 1.79± 0.20 (p<0.001). Mean nasal length was 2.27±0.30cmpreoperatively and 2.39±0.32cmpostoperatively (p = 0.002), and these changes in preoperative and postoperative nasal tip projection and nasal tip location ratios were also significant. Moreover, mean preoperative and postoperative nasal tip locations were also significantly different, which means nasal tips did not rotate cephalad after surgery. No revision surgery was required and no direct complication associated with the columellar strut graft occurred. Detailed results are provided in Tables 1 and 2.
