Changes in elastic properties of the nasal tip using Columellar strut graft versus tongue-in-groove method over one year after rhinoplasty

摘要

Introduction In this study, we decided to investigate the changes in elasticity of the nasal tip using Columellar strut graft versus toung in groove method over a year after rhinoplasty. Materials and methods In this before-after randomized clinical trial study, 44 candidates for rhinoplasty were enrolled Columellar strut graft group (n = 22) and toung in groove group (n = 22). Also 22 patients who referred to ENT clinic without any previous rhinoplasty and without any decision for it during the next year, considered as control group. One group underwent columellar strut graft and the other one underwent tongue in groove rhinoplasty and in control group participants received no intervention. Nasolabial angle and elasticity of the nasal tip were recorded and compared before the surgery, immediately after the surgery, 3 months and one year after the surgery. Result There was no significant difference between the mean elasticity of the nose and the nasolabial angle before the surgery, immediately after the surgery and 3 months after the surgery between the groups. However, there was significant differences in the mean elasticity of the nose and the nasolabial angle between the groups one year after the surgery (P value < 0.05). Pearson correlation coefficient test showed a significant correlation between nasal tip elasticity 3 months and 1 year after rhinoplasty (P = 0.032, r = 0.459) and nasolabial angle 3 months and 1 year after rhinoplasty (P = 0.045, r = 0.431). Conclusion According to the results, it can be concluded that the both the Columellar strut graft and toung in groove methods improve elastic properties of the nasal tip and nasolabial angle after rhinoplasty compare to the control group.
