This study introduces a new computer-aided design (CAD) workflow for creating 3D surgical models in resource-limited settings. These 3D models enhance patient consent, education, and surgical planning for complex cases.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Biomedical Engineering
  • Medical Imaging

Background:

  • Resource-limited surgical settings present unique challenges for complex procedures.
  • Access to advanced surgical planning tools is often limited in outreach programs.
  • Traditional methods for surgical planning may not adequately address complex anatomical reconstructions.

Purpose of the Study:

  • To describe a novel workflow for in-house computer-aided design (CAD) and 3D model production.
  • To evaluate the utility of patient-specific 3D models in a resource-limited surgical outreach setting.
  • To assess the impact of 3D models on patient consent, surgical education, and planning.

Main Methods:

  • Utilized preoperative computed tomography (CT) imaging obtained locally in Haiti.

  • Developed an in-house computer-aided design (CAD) workflow.
  • Produced rapid-prototyped 3-dimensional (3D) mandibular models for patients with ameloblastomas.

    • Main Results:

    • Successfully implemented a novel CAD workflow in a resource-limited environment.
    • Generated patient-specific 3D mandibular models from local CT scans.
    • Demonstrated the use of 3D models for patient consent, surgical education, and planning.

    Conclusions:

    • In-house CAD and 3D modeling offer a viable solution for surgical planning in resource-limited settings.
    • 3D models significantly aid in patient consent and surgical education for complex cases.
    • This workflow has the potential to improve complex surgical outcomes through enhanced planning and anatomical reconstruction.
