Accuracy and Security Analysis of a Cranio-Maxillofacial Plastic Surgery Robot Equipped With Piezosurgery in Genioplasty

Abstract

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. The surgical plan was designed as an ideal scheme (control group). Patients underwent traditional surgery according to the preoperative surgery plan (clinical group). Guided by surgical navigation, the osteotomy was operated on patients' same size plaster model using the surgery robot equipped with a piezosurgery (robot group). At last, the accuracy was calculated by CT data. There was no significant difference between the robotic group and control groups in the postoperative measurement index (P < 0.05). There was no significant difference between the robotic group and the control group (P > 0.05) in the line of osteotomy, but there was a significant difference between the clinical group and the control group in the line of the osteotomy.

Oroantral Communications: Clinical Efficacy of a Double-layered Technique With/Without the Palatal Connective Tissue Flap: A Superiority, Single-center, University-based Randomized Clinical Trial

“…To compensate for the risk of OAC relapse after surgery, the use of double-layered techniques has been suggested, with the characteristic increase in wound vascularization and stability. [10][11][12] This study sought to evaluate the combination of a buccal trapezoid flap with a pedicle palatal connective tissue rotational flap against the classic buccal sliding flap.…”
