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.

This study aims to verify that the craniofacial plastic surgery robot with piezosurgery is more accurate and safer than traditional operations in genioplasty. This study chose data from the Digital Plastic Surgery of Plastic Surgery Hospital in the Chinese Academy of Medical Sciences and Peking Union Medical College. The CT data of the patient's skull were reconstructed in the software, and the authors designed the measurement index.

Introduction: Mental nerve injuries with neurosensory deficits, asymmetries, and intra-operative bleeding are the main immediate complications of genioplasty. Following a recent systematic review, three-dimensional (3D)-printed cutting guide could improve the predictability and accuracy of this surgical technique avoiding postoperative asymmetries. Furthermore, anatomical structures in the surgical area (mental nerve and teeth roots) are better protected, reducing the morbidity and providing safer results.

Introduction: A retrospective clinical study was performed regarding the minimally invasive-guided genioplasty technique (MIGG technique) described in a previous clinical note. The aims of this clinical study were to study the incidence of immediate complications with this technique compared with a control group using a nonminimally genioplasty technique, to validate the accuracy of the three-dimensional (3D) printed cutting guide, and to evaluate the duration of the surgery and the satisfaction of the surgeons with this technique.
Materials And Methods: One controlled group, including 56 patients, operated with a classical genioplasty and one group, including 24 patients operated with the MIGG technique.

Background: The chin is the most prominent and median sector of the lower third of the face giving harmony to nose and lips. The authors present the application of piezoelectric scalpel for the correction of different chin deformities. The distinctive characteristics of this device allow the authors to avoid or reduce the immediate genioplasty complications.
