15 patients with maxillofacial trauma who underwent surgical repair at San Francisco VA Medical Center
Procedure: Surgical repair of maxillofacial trauma
Patients will undergo whatever needed surgical repair of maxillofacial trauma that is necessary. Records such as CT imaging and plaster models of the jaws will be utilized in the standard way to plan and carry out the surgery. The CT scan will also be used within the visuohaptic computational environment to develop and evaluate the user interface. The amount of time taken to work up and plan surgery using standard surgical practice and using the computational platform will be compared. Real surgical outcome will be compared to the simulated outcome using the proposed software tool.
The proposed tool will allow surgeons from different specialties to simulate, plan and iterate on complex procedures based on individual patient data in 3-D from a CT scan. The software will allow surgeons to both see and feel the results of their interventions - for example, the quality of the bite or bone alignment of a reconstructed jaw following severe trauma - before the actual surgery, leading to better planning, fewer errors, shortened surgery time and improved outcomes for the patients. The purpose of this study is the evaluation of a visuohaptic planning system for mandibular trauma surgery that is based on interactive manipulation of CT data.
