목적: Recently, sculpturing of projected and sharp nasal tips as is usual in Caucasians has been of great concern in Asian rhinoplasty. However, tip surgery in Asians should be performed in a different way from tip surgery for Caucasians due to anatomical differences. It is commonly required to have a significant tip projection based on a strong tip support. The authors designed a novel method of an endonasal extended columellar strut (EECS) to project the nasal tip significantly while avoiding hard fixation, and this study aimed to evaluate the usefulness of the EECS in Asians. 방법:A retrospective study was performed on 40 patients who underwent EECS from March 2012 to August 2014. Photographs taken preoperatively and postoperatively were analyzed. The tip projection, the ratio of the length of the infratip lobule to the total length of the tip, and a columellar labial angle change were measured. Overall, surgical outcomes were rated into three grades (excellent, good, and fair) by two experienced rhinoplasty surgeons. All patients were asked to rate their cosmetic satisfaction with a visual analogue scale (VAS, 10 points). 결과:Of the 40 patients, 23 were male and 17 were female, and the age ranged from 17 to 55 years (mean age, 28.4 years). Postoperative nasal tip projection significantly increased from 24.2 mm to 26.7 mm (p< 0.01). The ratio of the length of the infratip lobule to the total length of the tip mildly increased from 0.45 to 046 in males and remained unchanged at 0.48 in females. The columellar labial angle significantly increased from 86.9 mellar labial angle Surgical outcomes were rated by two experienced surgeons as excellent (40%), good (42%), and fair (18%). Subjectively, patients graded their satisfaction approximately 8.7 on the visual analogue scale. 결론:This novel EECS technique enables satisfactory tip projection in Asians while maintaining a natural ratio of infratip lobule to total length of tip while leaving no external scar.
