Accuracy of the execution of the genioplasty
Achtergrond van het onderzoek
In this study, we investigate whether or not the accuracy of genioplastic surgery improves with the use of patient specific cutting/positioning guides.
The positional changes of the chin segment are nowadays planned using 3D computer technique. Compared to the older 2D planning the complexity of the planning has increased dramatically. To transfer the 3D computer plan to the patient during the surgery patient specific guides are frequently used. It is not known if these guides actually improve the accuracy.
Doel van het onderzoek
Application of patient-specific guides will improve the accuracy of the execution of the genioplasty
Onderzoeksopzet
Before surgery: preoperative (CB)CT scan
Surgery: surgery time
After surgery: postoperative (CB)CT scan
Onderzoeksproduct en/of interventie
Execution of genioplastic surgery with patient-specific cutting and repositioning guides versus conventional method (without guides)
