Popis: | Background Control and maintenance of nasal tip position are critical in rhinoplasty. Two frequent methods of exerting tip control are columellar strut and caudal septal extension graft. However, no quantitative data exist comparing the two methods over time. The purpose of this study was to analyze maintenance of tip projection and rotation following either columellar strut or septal extension graft. Methods A retrospective cohort study of patients undergoing rhinoplasty was reviewed. Three-dimensional photogrammetric evaluation of patients with either columellar strut or septal extension graft to increase tip projection was performed. Anthropometric points were analyzed in a blinded fashion. Outcome variables were tip projection, nasal length, the Goode ratio, and tip rotation. Results were stratified based on technique and compared statistically. Results One hundred six patients were included. Overall, 66 percent were female, with an average age of 34.5 years. A columellar strut was used in 42 percent of cases (n = 45), and a septal extension graft was used in 57 percent (n = 61). Analysis showed greater maintenance of tip rotation over time with the septal extension graft compared with the columellar strut [-1.01 percent change (p = not significant versus -5.08 percent change (p = 0.009)]. Tip projection, nasal length, and the Goode ratio decreased over time for both groups, but the differences were not statistically different. Conclusions Nasal tip projection and rotation appear to decrease from the immediate postoperative position. In this study, both septal extension graft and columellar strut exhibit similar changes in tip projection with time; however, septal extension graft is better able to preserve tip rotation compared with the columellar strut.
