    Background:

    • Interactive computer-based simulation is increasingly used for craniofacial surgical planning.
    • Current limitations include subjective visualization without objective measurement, impacting spatial accuracy.
    • Objective evaluation methods are crucial for validating simulation fidelity.

    Purpose of the Study:

    • To investigate error sources in craniofacial surgical simulation evaluation.
    • To objectively compare simulation accuracy against post-operative outcomes.
    • To establish validated methods for assessing surgical simulation fidelity.

    Main Methods:

    • Quantified linear and angular measurement errors.
    • Assessed surface match accuracy using voxels and degrees.

    Related Experiment Videos

  • Evaluated Boolean subtraction method accuracy.
  • Applied validated methods to compare pre-operative simulations with post-operative results.

    • Main Results:

    • Linear and angular measurement errors were within +/- 1 mm and 1 degree.
    • Surface match errors were up to 3 voxels and 4 degrees.
    • Boolean subtraction methods demonstrated 93-99% accuracy.
    • The simulation method accurately depicted surgical outcomes.

    Conclusions:

    • Validated testing methods confirm the accuracy of the craniofacial surgical simulation used.
    • Further patient studies are needed for statistical significance.
    • Validated simulation can aid pre-operative planning, post-operative assessment, and surgical technique evaluation.
