Oral and maxillofacial surgery Mentoplasty Genioplasty Aesthetics Clinical trials


Introduction: In the context of oral and maxillofacial surgery, orthognathic surgery (OS) is used to improve the patient's facial appearance and to correct maxillary and mandibular deformities resulting from malocclusions, disease, or trauma. Objective: It was carried out a concise systematic review of the main clinical approaches to genioplasty (genioplasty), as well as the results of more current clinical studies, to show the state of the art of this surgery. Methods: The rules of the Systematic Review-PRISMA Platform were followed. The research was carried out from February 2022 to May 2022 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 108 articles were found. In total, 68 articles were fully evaluated and 23 were included and evaluated in this study. And of the total of 23 articles, only 09 articles were developed as the main clinical results. A total of 16 articles were excluded because they did not meet the GRADE classification, and 45 were excluded because they were at risk of bias. Mentoplasty represents one of the most common auxiliary procedures and may be associated with corrective surgery for dentofacial dysmorphisms. However, care must be taken with mental nerve injuries, asymmetries, and intraoperative bleeding are the main immediate complications of mentoplasty, and to minimize these risks, the ultrasonic piezoelectric osteotomy with the selective cutting of the mineralized structure stands out. Furthermore, one-piece mentoplasty based on a three-dimensional impression model proved to be very successful for the natural modeling of the mandible. Also, it has been shown that the use of piezotomes is advantageous in mentoplasty surgery compared to traditional surgical instruments. In the context of hylotherapy, the results of the study indicate slightly less residual edema at 18°C temperature on the 30th postoperative day. Finally, in orthognathic surgery, a fibrinolytic shutdown is significantly amplified by tranexamic acid.
