Background: One of the most important stages in rhinoplasty is the control of nasal tip rotation. Different techniques have been proposed to achieve this goal. We aimed to compare the effects of two methods of Septocolumellar Suture (SCS) and Lateral Crural Overlay (LCO) on nasal tip rotation by measuring of Columella-Labial angle.
Methods: In a single-blinded clinical trial, 148 patients were selected among the patients who were candidates for rhinoplasty in Sina Hospital in Tehran, Iran 2024. The patients were randomly divided into two groups (each group contained 74 subjects). The patients in the first group were operated on using LCO technique, and the patients in the second group were operated on using SCS technique. Columella-Labial angle of the samples were evaluated using the photographs of the samples before and six months after surgery. The obtained results were compared using SPSS software and t-paired and Mann-Whitney statistical tests.
Results: The mean Columella-Labial angle in both groups was more than that before surgery (P<0.001). The mean Columella-Labial angle before surgery in the SCS group were higher than that in LCO group and this difference was significant (P<0.001). The Columella-Labial angle difference was also significant between the two groups after surgery (P = 0.005), and Columella-Labial angle in LCO group was higher than that in SCS group (P <0.001).
Conclusion: LCO technique increase Columella-Labial angle more than SCS technique. Therefore, it is recommended that LCO technique to be used in patients with who need greater Columella-Labial angle change.
