Patients with a history of nasal procedures or cleft lip surgery were excluded. Group 1 received a cinch that passes through the anterior nasal spine, and Group 2 involves only soft tissues. A descriptive analysis was performed, and the normality of variables was assessed using the Shapiro\u2013Wilk test. The repeated measures ANOVA test was then used to evaluate changes over time between the two groups. When the assumption of sphericity was violated, the Mauchly\u2019s test, Greenhouse\u2013Geisser, Huynh\u2013Feldt, and Lower-Bound tests were used to correct for it. Between- and within-subjects effects were analyzed using Type III sums of squares.
