The aim of this study was to compare the postoperative complications during genioplasty using piezosurgery devices or traditional rotating drills. Forty patients underwent genioplasty to solve their chin anomalies. This study showed that, using piezosurgery, pain and swelling were reduced compared to the traditional technique in the immediate postoperative period of healing (within 15 days). Paresthesia was observed in all patients up to 15th postoperative day, independently of the used surgical technique, but at the sixth postoperative month it was completely absent.
