ClinConnect Summary

This clinical trial is looking at a new way to help patients better understand how they might look after undergoing orthognathic surgery, which is a procedure to correct jaw and facial bone problems. The researchers want to see if a computer program can accurately predict the changes to a patient's face after surgery. This program uses advanced imaging technology to create a 3D model that simulates what the surgical results will likely look like. By comparing these simulations to actual results from scans taken six months after the surgery, the team hopes to provide patients with a clearer idea of what to expect in terms of their appearance post-surgery.

To participate in the study, you need to be over 18 years old and scheduled for certain types of jaw surgery. You should also be able to understand French and give your consent to be part of the study. Participants will undergo their usual surgical procedures and will receive a pre- and post-operative scan to help evaluate the accuracy of the program’s predictions. This study is not yet recruiting participants, but it's a great opportunity for those who want to have a better understanding of their surgical outcomes.
