Description
Summary:•Protruding ear can causes low self-esteem, leading patients to undergone otoplasty.•Otoplasty with or without conchal preservation significantly reduce the deformity.•Careful analysis of the auricular deformity to choose the best surgical technique.•Eclectic technique with conchal remaining suture is effective for ear correction.•No significant difference between otoplasty with and without conchal preservation. Prominent ear abnormalities affect 5% of the population. A prospective, double-blind study of patients who underwent otoplasty procedures to correct these abnormalities was conducted to compare two surgical techniques. They diverge by the preservation or not of conchal cartilage. The two techniques were compared by measuring the cephalo-auricular and scapho-conchal angles. Measurements were performed in pre and 6-months post-operative periods using alginate molding. Twenty patients were randomly assigned to two groups (with and without cartilage preservation) with 10 participants each. Student’s t-test, Covariance Analysis Model (ANCOVA), and non-parametric Mann–Whitney were used in the statistical analyses. A significant reduction in the average of the cephalo-auricular and scapho-conchal angles was observed in both surgical procedures (p
