Abstract
Purpose: To evaluate our surgical outcomes by comparing our surgical plan to the outcome of the surgery and evaluate our efficacy using Virtual Surgical Planning and Medical Modeling software. Our aim is to determine the quality and validity of Virtual Surgical Planning when comparing pre-surgical plans with post-surgical outcomes. Patients and Methods: A cohort study was conducted for patients who underwent orthognathic surgery at a single institution. Utilizing virtual plans and models, select points for the virtual plans were compared and superimposed with that of the actual surgical movements. The primary predictor variable were the pre-surgical virtual plans of movements; the outcome variable consisted of the actual post-surgical movements. Statistical analysis was computed via IBM SPSS Version 25 software utilizing a paired t-test assuming equal variance with alpha (p<0.05). The sample of patients included those who had pre-operative and post-operative cone beam computed tomography scans, a virtual surgical plan, CAD/CAM splints, and LeFort I osteotomy and bilateral sagittal split osteotomy.Results: The study consisted of ten patients between the ages of 18-51 years old. Pre and post surgical plans were superimposed and four points of measurement were compared along 3 dimensional planes. There were no statistical significant associations between the virtually planned and post surgical planned values.Conclusion: Our results suggest that the use of virtual surgical planning in orthognathic surgery yields favorable and accurate surgical outcomes regarding rotational movements with minor degrees of discrepancies.
Highlights
Orthognathic surgery is a procedure commonly performed to correct dentofacial deformities and malocclusion
Outcome data was assessed by calculating accuracy using Box and Whisker plots of the superimposed scans determining difference planned to post-operative
We utilized 3-dimensional imaging to collect data points of hard tissue landmarks from cone-beam computed tomography (CBCT) scans that were taken within one week following the surgical operation
Summary
Orthognathic surgery is a procedure commonly performed to correct dentofacial deformities and malocclusion. The goal of any pre-surgical work-up is to minimize error in order for the actual surgery to yield favorable results. More surgeons are utilizing Virtual Surgical Planning (VSP) as opposed to hand tracing the surgical treatment objective and stone models. This is because VSP potentially minimizes time, cost, and human error that can arise when performing preliminary work-ups [3,5,6,7]. Our null hypothesis is that there is no statistical significance for those who received orthognathic surgery when comparing surgical outcomes with the pre-surgical virtual plans
