Data were presented as mean ± standard deviation for each group. P-values were calculated by one-way repeated measures ANOVA test. *Post-hoc analysis was performed by Bonferroni method. Statistical significant threshold was defined as p < 0.05. Last = Last follow-up, N = Number; Post = Postoperative; Pre = Preoperative.
